Luzhou, Sichuan issued a notice to win the Battle of Blue Sky embodiment. Program requirements, to promote ultra-low emissions to upgrade the steel and cement industries, and increase efforts to eliminate small coal-fired boilers, phasing out the whole 10 tons / hour and below the coal-fired boilers. Details are as follows.
1, to accelerate the development of clean energy. Scientific and orderly promote clean energy development and utilization of hydropower, natural gas (shale gas), wind power, solar, biomass and so on. By 2020, the city's total primary energy consumption of 12.48 million tons of standard coal, total coal consumption control in less than 6.5 million tons, accounting for the proportion of total energy consumption control in less than 42%, the newly constructed and put into operation a large municipal solid waste incineration power plants, garbage power generation capacity of 12MW, a new wind farm installed capacity of 48MW, the development of distributed PV installed capacity of 5MW, the new large biogas 5. Improve the construction of reservoirs for natural gas production and marketing system.
2, to promote the use of clean coal. Efforts to increase coal washing, coal simultaneous construction of new coal washing facilities, supporting the completion of existing coal mines coal washing facilities in accordance with points Area. Improve coal quality and use of standard industrial, commercial coal do not comply with environmental standards required by regulations of coal quality merchandise. Prohibit the circulation and use of low-grade bulk coal, bulk coal investigated and dealt with according to the law without a license behavior. Increase the civil bulk coal clean governance efforts to promote electricity instead of coal, substitution of gas for coal, to promote the use of clean coal, advanced civilian stoves, strengthen civil bulk coal management. Strengthen regulation and control coal use in autumn and winter.
3, to carry out comprehensive improvement of coal-fired boilers. Increase efforts to eliminate small coal-fired boilers. By 2020, the county level and above cities phasing out the built-up area per hour and 10 tons of steam coal-fired boilers, in principle, to a new 35 tons of steam per hour of coal-fired boilers, in principle, to other parts of the new 10 per hour tons of steam coal-fired boilers. Ambient air quality standards are not areas should further increase efforts to eliminate.
4, increase Condensing units and cogeneration units technological transformation efforts, speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate network and bulk coal fired boilers within the coverage area. In areas not have cogeneration district heating conditions, a plurality of existing coal-fired boilers of small, actively promote the implementation alternative energy.
Steam boiler water treatment equipment What is the role of the boiler itself? Core Tip: boiler water treatment of new fuel gas steam and basic purpose. Well boiler water treatment is an important element to ensure the safe and economic operation of the boiler. Due to the high combustion temperature of the oil, gas. And most of the oil, gas boilers (especially imports of fuel gas-fired boiler) small size, compact structure, higher requirements for water quality, water treatment, if done well, it will cause boiler fouling, corrosion, not only a waste of fuel and easy caused by blocked pipes, burst pipes and other accidents, causing serious boiler will be scrapped biggest economic losses. Therefore, fuel oil and natural gas boilers have to do a good job of the basics of boiler water boiler water treatment.
Increase productivity boiler system must first be optimized for verification, including the entire steam system for a complete analysis, and focus on some of the energy waste places. Via check can often find opportunities to save energy, increase productivity, and environmental protection have a positive contribution of. Check includes a steam generation, distribution, use and condensate recovery. The main steam waste requiring special attention place: exhaust gas boiler: boiler efficiency emissions system the most important indicators, the loss of energy is the most important place. Combustion air: general air enters the combustion furnace of the genus room temperature, require a lot of heating energy, i.e., the most commonly used power saving mode using a high temperature exhaust gas to preheat the combustion air of boiler, boiler efficiency can be significantly improved. The fuel / air ratio: Proper oil / gas mixture can only complete combustion, if the lack of air, combustion is incomplete, not only smoky pollution, environmental protests caused nearby residents, and easy carbonized grease gun and boiler heating tubes affect performance. If excess air is formed wasted energy, reducing boiler efficiency. Via the oxygen content of the tail gas can appropriately adjust the oil / gas ratio. Oil-fired boiler exhaust gas which content 3%, i.e., the excess air of about 15%, as the standard combustion control.
Gas-fired steam boilers are a very wide range of special equipments, widely used in food, chemical, paper, textile, construction and other industries. In the process of loading and installing a gas steam boiler, some problems must be paid attention, otherwise it may cause a certain degree of economic loss.
1. Pay attention to the following matters during the loading and unloading and handling of gas-fired boilers: the lifting capacity of the lifting equipment should match the weight of the lifting boiler. The lifting lug on the boiler with the lifting lugs that cannot be used for lifting can not be used for lifting. The length of the steel cord should be reasonably selected to avoid the scratching of the furnace due to the improper length of the steel cord. The boiler must be protected from any damage during handling and handling.
2. Reserves for maintenance space When installing boilers, ensure that there is sufficient maintenance space around the boiler.
3. Setting and precautions for the base and base of the gas steam boiler The boiler body must be installed on the basis of 100-150mm above the floor of the boiler room. It must be confirmed with the technical personnel of the boiler manufacturing company in advance and constructed according to the basic drawings. The anchor bolts must be reserved on the foundation. The foundation shall be capable of withstanding the maximum weight of the boiler and the amount of water it holds. When installing the base, you must first position it. After positioning, adjust to the same length of the two diagonals of the base, and then tighten all the fixing bolts. The installation of the base is carried out with reference to the reference line.
4, general precautions Be careful not to tilt and impact the boiler and accessories too much. No combustibles can be placed around the boiler. Do not use oil and water to smother the boiler. The boiler should normally be installed in a separate boiler room. The new gas-fired boiler room should not be connected to the house. The boiler room shall not be connected to Class A, Class B and Category C fire hazard rooms using flammable liquids. If connected to other production plants, the application firewall is separated.
5. The fire resistance grade and fire protection requirements of the boiler house building shall comply with the requirements of the Code for Fire Protection of Building Design and the Code for Fire Protection Design of High-rise Civil Buildings. The ground of the gas steam boiler room should be flat, non-flammable, no water accumulation, and the foundation load should meet the requirements. The power supply voltage of the gas steam boiler room should be stable to avoid causing the electrical components to burn out. If the voltage is unstable, it is recommended to install a voltage regulator. Ventilation equipment should be installed in the boiler room, and the boiler should be kept at room temperature below 50 °.Free Chat
