To comprehensively promote the prevention of air pollution control work, steadily enhance the quality of atmospheric environment, located in the northern part of Heilongjiang Province held a mobilization meeting Sunwu out of small coal-fired boilers to May 7.
Conference announced the "2019 Sunwu urban area out of 10 tons of steam per hour and coal-fired boiler embodiment."
To promote the elimination of built-up area of small coal-fired boiler work, the relevant departments should strictly follow the higher level requirements, the investigation to find out the use of coal-fired boilers and urban planning area of built-up areas, with their own reality, do a good job to implement; should attach great importance to raise awareness, according to the embodiment and objectives, and take various measures to actively promote the complete phase-out of coal-fired boilers small task; to actively publicize the relevant policies, regulations and requirements to the boiler owners, guided by the responsibility to implement, clear time node . To seek truth from facts, objective science, policy guidance, strict enforcement of the principle, in order to reduce air pollution, improve air quality and protect people's health as the goal, according to the classification regulation, departmental interaction, Duocuobingju, the overall advancement of the process steps to form a government command , business differentiation, market-driven, effective supervision, public participation in new air pollution control mechanisms, to promote the phase-out of coal-fired boilers built-up urban area.
Classification bottom side Henan hot water boiler fuel boiler fast small as we explain the use of hot water boiler fuel What are assembled into a notebook-type water tube furnace control panel, all of the action are stored on the smart chip, maintaining a furnace automation, intelligent, intelligence and personalization, to keep the Zidongkongzhi furnace temperature. This hot water boiler is the energy conversion facility, the type of kinetic energy of the furnace with a fuel chemical energy, electromagnetic energy, heat energy, etc. smoke, and after converting furnace, must be provided outside the output energy of steam, hot water or inorganic heat carrier. Gas boiler effect ignition system and fuel gas is ignited depending on the compound, the key member includes: an ignition transformer, electrical ignition stage, electric high-voltage cable fire. Compare Security Council this ignition system called electronic pulse ignition, such as natural gas is Zhuoyi energy-saving boiler manufacturers widely used. Its convenient and save time, as long as the finger can be pressed, and high safety factor, because life is not prone to production safety accidents death Xihuo arise, if the situation Xihuo appears, immediately turn off the control relay, off-gas loop . Computer processing furnace boiling hot water boiler part of the control panel, all functions are stored on the smart chip, maintaining the automated, intelligent and personalized furnace, furnace temperature to achieve a Zidongkongzhi. Automatically terminate the heating temperature is too high; the display font size to display the temperature, boiler water temperature straightforward. Exceeds the temperature was warmed automatic termination; display font sizes that vary depending on temperature, the furnace temperature simple. 2. boiler water temperature can provided 10 ℃ ~ 100 ℃. The furnace can not only produce bath with boiling water, boiling water can produce consumption, either to the furnace, but also to the furnace. 3. The top vents under the furnace wall, furnace in the non-pressure situation, the explosive risk-free, bare metal provisioning with over-temperature maintenance (inside the furnace when the temperature is high, heat pipe automatic termination of work to do, and came bee song alarm). Again when maintenance overtemperature (secondary circuit is automatically disconnected when the temperature exceeds 105 ℃ furnace shell), and less water to avoid air burning maintenance (water is less than when the furnace is very low amount of water in the secondary circuit of the furnace shell temperature exceeds 105 ℃ auto-off), when the water is less than the low water furnace automatically disconnect the secondary circuit, the furnace terminate work to do and came buzzer alarm) and other security Council safeguards. Much of this hot water boiler is converted from a hot water boiler is made early, it should belong to the ecological pot of water through the bad within the furnace. To ensure the safety and reliability of the coefficient of water circulating furnace, the furnace has to be a predetermined aspect ratio, and thus a large volume of such a heating furnace, the steel consumption and to enhance profits depend.
Operation of the gas boiler has what measures? Gas-fired boiler in many large factories or companies which, basically is a kind of device can see, of course, such a device is actually in the process of actually running, more or less have some of their own operating standards, from the current situation, when they run have more to do security measures. So what are run gas boiler measures at run time? (1) After a series of gas-fired boiler inspection, maintenance, basically in the process of running to them in accordance with the relevant requirements to run, there will have a lot of protection, even if they want to determine the importance of the protection of the entire work. (2) gas-fired boiler in the process of ignition, more or less likely to occur will require some regulations, such as they might meet some of the fuel, but the fuel pressure in the whole process of evaporation or mist, more or less will meet some of stroke, some extent, when the entire examination will also return to substantially a normal state, they energize the disable signal is short, when the flow rate of the whole is greater than a single second branched oil gun 0.65 kg when it should launch this gun running. (3) gas-fired boiler at the time of ignition, be sure to pay attention to look at all of the furnace temperature, the temperature inside look at the major, and the entire main steam pressure in the process of rising more or less there will be some obvious favoritism, or the case of speech do not rise, so then we should immediately go to the examination of fire tank. in addition, if found throughout the fuel into the furnace did not catch fire, it would tightly shutdown.
When the pressure of the upright steam boiler 20 ton protection small small steam boiler pressure exceeds the rated boiler steam pressure protection, the need for chain protection: is shutdown, the system stops the combustion; fire mouth can also be varied, single-stage or two-stage combustion, You can adjust the amount of oil, so the buck, to ensure the safe operation of the boiler. Fuel (gas) pressure protection and steam boiler water, as the use of multiple protection: the pressure controller typically use two pressure controller, the pressure signal converted to an electrical signal, the electromechanical converter, the function of the high pressure, or low levels of signal The electrical switching loss, external circuits or automatic control chain protection. Common pressure controller and pressure gauge, vapor pressure overpressure alarm can cut off the burner limit is reached; pressure controller adjusts single fire or dual fire burning the actual operating pressure; for large burner, the pressure may be adjusted according to the size of the size of the amount of fuel, and always maintain a stable pressure relief valve operation is the last line of defense to protect the boiler, the boiler pressure exceeds the limit, according to the set pressure relief valve design feature, the exhaust pressure relief, to ensure the normal operation of the boiler. Temperature protection temperature protection is an important procedure in the safe operation of the boiler, is particularly important for the regulation and protection of the boiler temperature steam; at the same time to regulate protective role in over-temperature hot water boilers. Conventional boiler temperature protection means is a bimetallic temperature controller.Free Chat
