To prevent air pollution and ecological damage, protect and improve the environment, promote the construction of ecological civilization, and promote sustainable economic and social development, Nanjing, Jiangsu Province to develop and launch the "Nanjing Atmospheric Pollution Prevention Act," played on May 1, 2019 official implementation.
1, the implementation of energy consumption and total coal consumption control and intensity control system. City of total energy consumption and coal consumption control administrative department with the relevant departments in accordance with provincial and municipal energy conservation requirements, the preparation of periodic control energy consumption and total coal consumption embodiment, the Municipal People's Government for approval.
2, high-pollution fuel combustion zone ban prohibits the sale, burning polluting fuels; prohibit new or expanded high-polluting fuel burning facilities; has been completed, should stop using within the prescribed period the Municipal People's Government, or switching to natural gas , liquefied petroleum gas, electricity and other clean energy.
4, petrochemical enterprises should strengthen the recovery of combustible gases. Flaring device should be used to deal with emergencies, not as a daily air pollution treatment facilities.
5, to encourage the production, use, or free of volatile organic compounds less volatile organic content of the feedstock and products. Surface coating, packaging, printing, furniture manufacturing and other industries should use low VOC content of products. Petrochemical and other organic solvent, the company should improve the production process, a low content of volatile organic materials and products.
6, resulting in production and business activities of volatile organic waste gas should be carried out in a confined space or equipment, and the installation of, use of pollution control facilities. Shipbuilding and other production and business activities can not be carried out in a confined space, and building (structure) building routine maintenance of live animals, roads, bridges, etc., should take effective measures to reduce emissions of volatile organic compounds.
Problematic fired coke oven boiler (1) Henan small boiler gas boiler should be noted, by the Henan coal into gas boiler, i.e. the original becomes a negative pressure is now slightly positive pressure combustion burner, the furnace must be noted that the structure and the sealing wall problem; (2) prevent explosion of the furnace, a gas fired boiler furnace to Henan, when defective or incomplete combustion of fuel atomization gas in the furnace or heating surface of the end aggregate, fire or explosion occurs, and therefore, in appropriate sites shall boiler explosion vent means, while the control program should be added to the ignition and flame protection device of automatic control, to ensure safe operation of the boiler; (3) the selection and arrangement of the burner close to the furnace in the form of, should the flame in the furnace better fullness without forming dead air; adjacent flame of the burner to avoid mutual interference; low load flame holding in the furnace central position, offset from the center of the furnace to avoid the flame center of symmetry; unburned gas-air mixture is not in contact with the heated surface , to avoid the formation of incomplete combustion gases; hot flame to avoid high-speed heating surface erosion, in order to avoid excessive heating surface so that the wall strength of overheating. Burner arrangement also consider the gas pipe and duct arrangement, easy to operate, inspection and maintenance; (4) Mechanized layered coal-fired boiler, gas boiler to change Henan, first removing its longitudinal arch, taking into account the increase in the bottom heating surface to replace the grate, grate to prevent overheating burn; (5) gas velocity Henan convection heating surface is not limited by the gas boiler ash abrasion conditions, gas velocity can be increased properly, so the convection heat transfer heating surface coefficient increases, without increasing the heating surface of the boiler, can increase the pressure of the boiler, steam-water separation capability should be noted that at this time means the pot to ensure the quality of steam, hot air for the boiler had particularly important.
Gas-fired center coke oven boiler reminds you to shut off the fuel supply of the furnace immediately in case of quenching, close the electromagnetic valve for gas supply (oil and return), and then close the fuel supply valve for the operation of burners. Operate quickly so as not to cause a vicious risk when fuel continues or resumes supply. At the same time, find out the causes of boiler quenching, remove the found faults, and make preparations for restarting.
Environmental coke oven boilers using different fuels What are the advantages first to show that environmentally friendly boiler is a more general concept. It is not classified according to the fuel used, but to a variety of standard boiler flue gas emissions to meet state regulations. So what are environmentally friendly boiler fuel to use it? Commonly used natural gas fuel, diesel fuel, electricity, methanol and the like. Natural gas is the most important environmental protection boiler, its fuel natural gas is a clean energy, combustion products discharged after treatment safety. Natural gas boiler maintenance costs of environmental protection is very low compared to the energy efficiency of is very high, such as our gas-fired thermal efficiency can reach 95%. This boiler is the government's most important eco-friendly boiler. Environmental protection boiler fuel diesel fuel use in general, because of the relatively low price of diesel, sulfur dioxide and other acidic substances produced by burning it after treatment can be safe discharge standards, supporting measures that it needs storage tanks, maintenance costs are lower thermal efficiency up to 90% or even higher. Electric heating boilers are environmentally friendly boiler, wire and cable facilities is required, it is zero pollution, low maintenance costs, but the state has requirements of energy conservation, power cuts in some places the situation may occur, especially in summer the peak period. This is also where you need particular attention. High energy-efficiency boiler hot methanol, facilities storage tank is required, but also the Government's strong support for environmental protection boiler.
