Recently, Zhongshan City, Guangdong Province, the ecological environment expanded Bureau held a working high-pollution fuel combustion zone ban will promote further urge the major companies on time and quality completion of boiler rectification task. It will be mentioned in the need to deeply Publicizing the newly revised "Air Pollution Prevention Regulations of Guangdong Province" and "boiler air pollutant emission standards" and to implement the next phase of work to expand the scope of the ban on burning zone, Zhongshan City.
District policy is to implement the ban on burning blue sky, Zhongshan City, to win the Battle of the most important, relevant departments, district towns, enterprises should pay full attention and positive action in order to "limit Forced, territorial responsibility, multi-pronged approach , coordinated implementation of the "principle, should work together to create synergy, take the following measures to ensure that all targets are met within the deadline.
According to published Zhongshan City, "about expanding the scope of high-pollution fuel combustion zone ban notice" requirement, in addition to coal-fired cogeneration thermal power plant units have been built high-pollution fuel industrial equipment must be removed or completed by June 30 this year clean energy transformation, all enterprises should actively cooperate with government departments to complete the rectification task on time and quality.
According to requirements "Boiler Air Pollutants Emission Standards" (DB44 / 765-2019), and from April 1 this year, the province's start step by step implementation of the new air pollutant emission standards boiler, new boiler effective from April 1 this year, in accordance with the different regions in which, since 1 July 2019 or 1 July 2020 to implement the new standard boilers. Compared with the original standards, new standards particulate matter, sulfur dioxide, nitrogen oxides and other pollutants received strict emission limits help to further reduce the total emissions of air pollutants.
The difference between low nitrogen gas boiler with ordinary coal-fired boiler from China after the latest air pollution emission standards introduced across the country have carried out air pollution control projects, ordinary coal-fired boilers due to serious pollution faced elimination and replacement process. Low nitrogen gas boiler because of its unique low nitrogen, clean, environmental advantages, namely a push into the market has been widely welcomed. Today, fast boiler come to you talk about the difference between natural gas boilers with low nitrogen ordinary coal-fired boilers. 1, differences in emissions due to the use of ordinary coal-fired boiler fueled by coal, according to the composition of coal, which determine the more discharged flue gas after the combustion of soot, ash, sulfides, flows into the atmosphere can result in serious pollution influences. A low nitrogen gas boiler using natural gas as fuel, almost no soot and other harmful substances combustion; low nitrogen after processing, harmful substances is reduced to a negligible extent. 2, ordinary coal-fired boiler combustion technology differences are mostly fed directly into the furnace of coal combustion, incomplete combustion of coal will be an inconvenience. Low nitrogen gas combustion boiler made a change in the natural gas and oxidant gas (air) are mixed in a certain proportion of advance before entering the furnace, so that the gas will be more fully combustion, fuel efficiency is also improved. 3, differences in the safety factor by coal-fired boiler explosion occurred in recent years across the country, we can see that a lot of coal-fired boilers there are still security problems, once the risk of an accident, whether it is physical security or economic interests will suffer great losses ,The consequences could be disastrous. A low nitrogen gas boiler for safe disposal can be seen in the following points. First, fuel storage and delivery are established directly connected to the pipeline, and the pipeline have done more treatment, both the quality and safety factors have been improved. Secondly, the current low nitrogen gas boiler mostly have joined the intelligent automatic control system; it just as fast boiler, each boiler is equipped with independent research and development of intelligent control system, with matching boiler is very high, people fireman only need to follow the instructions HD display menu operation, start to finish, adjust a variety of state (water supply, output ...), outage, etc., and easy to operate but also to avoid direct contact with the staff of the boiler. In addition, low nitrogen gas boiler with a comprehensive probe detection device, connected enterprise cloud services remote monitoring system, water level, pressure, temperature and other abnormal occurrence which step will be detected immediately and begin warning to remind people immediately see the boiler status fireman . Continuous technological innovation, is providing energy saving, high-quality boiler equipment lies. Low nitrogen gas boiler after many trials and engineering applications, and achieved great results; at present, has been widely used in many industries, not only protects the environment, energy conservation, but also to control the pollution, the technology is particularly worth the continued research and development applications.
Advantages and characteristics of electrically heated boilers: 1. The high quality heat source heating system can output the hot oil up to 350 ℃ for the thermal user under normal pressure liquid phase. The heating system all adopts Japanese Fuji temperature control instrument, uses the PID self-tuning intelligent temperature control technology, the control precision can reach ±1 ℃, the accurate control temperature range; The main heating power supply adopts solid-state module contactless switching circuit, adapts to frequent switching, and does not interfere with the power supply network. It also has anti-dry burning. The hot oil cooling system can be designed according to the user's requirements to meet the production process requirements of rapid cooling after heating up. 2. Energy saving, low operation cost of heating system is liquid phase closed-circuit circulation, the difference between oil outlet temperature and return oil temperature is 20 ℃ 30 ℃, that is to say, the temperature difference can reach service temperature only by heating 20 ℃ 30 ℃. At the same time, the equipment does not need water treatment equipment and there is no steam boiler running, run, drop, leakage and other heat losses, heat utilization rate is very high, compared with steam boiler, about 50% energy saving; Less investment in equipment because the heating system is simple, no water treatment equipment and more auxiliary equipment, boiler bear low pressure, so the whole system investment is less; 4. Safety because the system only bears pump pressure, heating system explosion-free The explosion is dangerous, so it is safer; 5. The environmental protection effect of environmental protection organic heat carrier boiler system is mainly reflected in the few emissions of flue gas, no pollution and thermal pollution. Characteristics: 1, low operating pressure: liquid phase conveying heat energy, can obtain a higher working temperature under lower operating pressure, heat carrier than the saturated steam pressure of water 70 times lower, the general operating pressure of heating is ≤ 0.3MPa. 2, high heating temperature: heating furnace heating temperature up to 280 ℃; automatic control of heating temperature, high sensitivity, stable heating. 3, safe and reliable: Fangkuai specialized in R & D and production of boilers, with Perfect operation control and safety monitoring device, easy to operate, safe and reliable. 4, environmental protection design: boiler equipment is equipped with a new type of electric heating system, electricity instead of coal, saving investment, environmental protection and pollution-free, at the same time the boiler heating up fast, high thermal efficiency, high efficiency and more economical!
Industrial gas steam boiler room planning considerations: industrial gas steam boiler room Planning Considerations What? Followed by the degree of technological progress from time to time, the rapid expansion of social economy, people's requirements for industrial gas boiler room planning have become more sophisticated. Now now, in the industrial gas boiler room planning there are still many achievements in urgent need of treatment, therefore, we have to enhance the learning and use of advanced planning practices and advanced technology, from time to time suspend the development and review of industrial gas boiler room planning, the industrial gas boiler housing plan is more suitable, safe, reliable and economical. 2, selection and use of industrial gas boiler at a reasonable selection of urban planning, boiler, environmental management and other mission boiler type is dropped purification, waste power, an important part of reasonable expenses. Set the cost of the boiler is one of the essential elements of when thinking of selection. Because the characteristics of industrial gas boiler itself, the boiler room and equipment to establish a more economical, should be used in high load industrial gas furnace heat boilers in order to reduce the volume of the furnace. Due to the absence of heating surface cleaner, slagging, wear results, the smoke may use a higher speed, reduced scale of the convection heating surface, convection through the rational placement control the industrial gas boiler capacity of coal-fired boiler with a more compact structure, dimensions small, light weight, in order to decrease equipment investment; supporting auxiliary boiler optional satisfactory work. Industrial demand for gas-fired boiler is not equipped with soot blowers, dust, slag and other equipment and fuel dryer slave device, and can save and land acquisition costs placed above equipment; the use of a gas pipeline walks as boiler fuel, not only no fuel storage equipment, supply calm and without prior preparation of fuel processing equipment, greatly simplified the trivial; civil engineering boiler room investment costs and other related costs will lower; no fuel storage, can save shipping costs, place and rest force. Boiler room non-essential equipment such as leak detection equipment for the surge equipment, measurement equipment, gas. Coal, oil, gas boiler three kinds of heat load in the opposite situation, a huge volume of coal-fired boilers, additional slack style drums, Fan, Java machine, dust collector, but also with storage of coal, slag heap place, It covers an area larger. Industrial gas boilers small volume itself, and these need not be equipped with auxiliary equipment, simply set up between a host and auxiliary room, set on more messy, covering economy. Industrial gas boiler city gas source is generally taken from the intermediate pressure gas supply line, the gas pipeline laying gas sampling point to the boiler room, then according to quell's brand, type and caliber regulating device applications, scheduling outlet pressure range, by metering the put into use. Establish a set fee just gas network tariffs, pipeline fees, hot walks pipeline fee. Gas pipeline network overall cost of capital is the sum of the gas company funds charged to the user, it can be determined depending on the circumstances around the gas company. Usually adopted buried gas pipeline type, buried depth is generally about 0.8m ~ 1.0m, seamless steel pipe can be selected or PE pipes, pipe surrounding sand 15cm ~ 20cm plating, hot water pipe laying relatively simple, somewhat messy steam pipe walks . 3, industrial gas boiler room planning results in the presence of 3.1. Selection of the size of the heat load of the boiler and its expansion tend to choose the boiler capacity, the number of great links. The larger heat load, single boiler capacity should be large. The near future can be greatly increased thermal load, it is also relatively large capacity boiler can choose, it will expand the load thought. The only thought to increase the long-term thermal load, the expansion device may leave the boiler placeholder deployment end in the boiler room, or space left on the total FIG. However, in the practice of project planning, often there is a lack of expansion heat load estimates, constitute improper boiler selection, pre-operation to cause unnecessary trouble. 3.2. Gas boiler gas regulator trivial results generally used in high-pressure (less than 5kPa) and medium voltage (5 ~ 150kPa) trivial. Gas usually before entering the boiler room will arrive this requirement. Now the gas hot water boiler for school is equipped with a high level of automation subsided, a calm requires the gas pressure is lower, so before further demand into a calm pace pressure boiler manufacturers themselves generally equipped. Gas pressure regulating trivial demands reliable equipment, but on the size of the gas pipeline valve is open due to the gas pressure when scheduling the gas pressure is high or low, and tempering will cause off, start and stop frequently subsided's configuration, thereby affecting the boiler work. 3.3. Gas boiler quality results planning standard gauge, the quality can not be ensured when the gas, should be provided or dust, oil and water, respectively, and a total closed drain valve before the gas main pipe before the regulator device. Most of the oil production plant in the use of oil with anger, it is often said of moisture in the summer cold weather, moisture and light hydrocarbons and other substances containing moisture, condensation will constitute a line blockage, an initiative to quell the flame, impact Heating. 3.4. Chimney condensate results because of the high thermal efficiency of industrial gas boiler, a low exhaust gas temperature, typically 180 degrees, the boiler room planning criteria (GB50041-2008) rules industrial gas boiler room chimney should be reinforced concrete or steel chimneys chimney. Chimney will appear directly in the outdoor summer steel chimney condensate freezing results, constitute icing light rusty steel chimney, would constitute a temporary corrosion, freezing severe affect chimney smoke. 3.5. The amount of air to quell the outcome's when quell Industrial gas boiler is in the boiler room, the air between the boiler must be satisfied the requirements apply to quell the device, otherwise there will be no abundant natural gas to quell working carbon monoxide poisoning.Free Chat
