Recently, Taiyuan, Shanxi Province Environmental Protection Leading Group issued a circular on promoting the transformation of ultra-low emissions and low nitrogen transformation of biomass environmental protecting coal fired dzl boilers gas-fired boiler. Resolutely implement - the latest requirements "2018 in Beijing, Tianjin and the surrounding areas in 2019 autumn and winter tackling air pollution comprehensive management action plan" in, and further reduces boiler emissions standards.
1, 2019 until October 31, the use of boiler tail decoration efficient dust removal, desulfurization, stock device is accomplished ultra-low emission biomass boilers transformation of the necessary funds by the counties (cities, districts) and users together to solve, not the municipal finance I grant.
2, October 31, 2019 update for ultra-low emissions of nitrogen gas boilers, electric boilers biomass boilers, municipal finance one-time grant 30 yuan / square meter construction costs, in part by the lack of counties (cities, districts) and user common solutions.
Way: by transformation to replace the low NOx combustion, a flue gas recirculation device installation mode, NOx emission is less than 30 mg / m item.
NOx emission cuts ≥50%, and the concentration value of less than 30 mg / cubic meter project, to give up prize money of 30% in accordance with the transformation of investment.
3, after December 31, 2017 the new gas boiler, should meet the emission requirements on Taiyuan low NOx combustion, but does not enjoy the low NOx combustion subsidies.
Personnel and to avoid faulty gas environmental protecting coal fired dzl boiler gas boiler prone to some fault in the use of the process in order to avoid it fails, we have to understand some of the considerations when using. When using a gas boiler, we should always carry out its care and maintenance of local failure timely maintenance and replacement, make sure it is working properly. Circulation pump pressure constant, the current increases and the flow drops, deterioration of the thermally conductive fluid, the viscosity increased, should be replaced or regenerated. New heat transfer fluid as a result of decomposition of aqueous or excluded gases in the system, should immediately open the vent valve of the exhaust gas. When the current is lower than normal circulation pump, the circulation pump efficiency is decreased, the flow rate decline may be heating pipes plug fouling, and should be cleaned. Low temperature liquid phase heat carrier outlet of the furnace, for lack of heat, and the exhaust gas temperature exceeds 300 ℃, the main problem is the fouling, soot blowing should be. As low exhaust gas temperature, the main issue is burning, mainly lack of the wind. Although the pressure furnace, the blast volume is not open, the furnace temperature is low, combustion insufficient strength. We should focus on rear seal machine check furnace slag, dust, etc. whether closing the ash outlet is good, with or without cold air leakage into large. Before and after the filter differential pressure increases, the pump inlet pressure drops, the filter may be stuck, the opening of the bypass, disassemble and clean the filter. Grate stuck. The reason is often broken or grate grate fall loose pins; coal grate has stuck to metallic inclusions; arched grate; slag filter (Eagles iron) sink tip and the grate stuck. Processing method: reverse hand grate plate debris removal, replacement breaking grate after the start, then jammed as startup, stop the rotation of the reasons detailed inspection to resolve. The iron eagle sink, both sides can pull the fire door pull hook n. Grate stop turning, it may be too loose chain, and sprocket meshing well, or badly worn sprocket, and chain-linked bad; the adjustment screws on both sides to re-adjust the tension grate, if still does not work, you need to exchange sprocket.
WNS type environmental protecting coal fired dzl boiler and gas boiler SZS What's the difference? After the state has increased in recent years, efforts to manage the environment, improve air quality, all walks of life are generally boiler retrofit or replacement gas boiler became a coal-fired boiler, the implementation of coal to gas boilers in large-scale, often encounter some customers when purchasing gas boiler, except consulting WNS type boiler and gas SZS type gas boiler, which both thermal efficiency higher? Now, I give you a brief overview about the difference between the two.
Traveling grate steam environmental protecting coal fired dzl boiler which also called chain grate steam boiler, can be divided into two types according to the fuels, one is traveling grate biomass fired steam boiler and the other is traveling grate coal fired steam boiler. In Zimbabwe, there is a rich coal reserve, therefore, traveling grate coal fired steam boiler for sale in Zimbabwe is popular and has earned good reputation.
