Recently, the Shuangyashan City, thoroughly implement the first meeting of the Central and the National Finance Committee, the province's environmental protection spirit of the General Assembly to further implement the "State Council on the issuance of winning the Battle of Blue Sky's three-year action plan" to do "atmosphere ten" task finishing verification and improve air quality living environment for the residents to protect the health of the people, combined with the actual situation, the specific "Shuangyashan City 2018 air pollution control implementation plan."
"Plan" focused on job content is to carry out comprehensive improvement of coal-fired boilers, effectively reduce coal pollution. Of built-up urban area shutdown, demolition, instead of using biomass fuel boiler inspection, investigation and comprehensive urban fringe areas built-up area if there is a new violation, missing, incomplete elimination of small coal-fired boilers, to eliminate incomplete, missing, "resurgence" boiler promptly dealt with severely, and formed out of work ledger, as planned phase-out. Existing "clear" action identified 28 small coal-fired boilers, before the end of September 2018, to phase out the "cleared" of work, and in strict accordance with the requirements "a furnace" during the establishment phase out the boiler archives for future reference. Planning the construction of central heating heat source, heat accelerate network construction and transformation progress, constantly expanding area of central heating and central heating ratio; advancing coal to gas, coal to electricity and other clean energy alternatives, to promote industrial parks and industrial clusters concentrated heat source, steam source facilities.
Battle of blue sky and started "out of coal-fired boilers" special action to start the county (district) level urban built-up area of 10 steam tons / hour and coal-fired boiler, tea furnace, operating coal-fired kitchen stove and other facilities, grain storage coal drying equipment out of work. County (district) to co-ordinate well out of work, organized a special team completed a comprehensive investigation of the status quo area coal-fired boilers, establish a list out of coal-fired boilers, the production out of specific programs, and to work out the boiler out of subsidies. Before the end of the first to eliminate a large number of pollution levels, residents reacted strongly to the coal-fired facilities.
Condensing gas boiler with coal-fired boilers What are the differences? Some may have which is not very clear to distinguish condensing gas boiler with coal-fired boilers, here we look at their specific differences, 1. The circulating fluidized bed combustion coal-fired boilers are coal by crushing equipment , by the belt into the coal bin, by using multicast coal stoker wind, thrown into the furnace; circulating ash by heating, fluidized combustion process. After coal to gas and coke oven gas and purge gas mixed together by the four burners directly injected into the combustor. 2. Combustion of Coal is mainly composed of water and ash content and the elements C, H, O, N, S etc., the heat released by combustion of coal to produce SO2, SO3, NOx ash and moisture, and SO2, SO3, NOx from the flue gas into the atmosphere, polluting the environment, cause harm to humans. And the main component of coke oven gas and purge gas are CO and H2, after combustion, produce mainly CO2 and H2O, SO2 emissions from coal-fired boilers is relatively gas boiler, SO3, NOx is much less. 3. Ventilation general negative pressure combustion coal burning boiler, a combustion process with the base by the induced draft fan and the blower mating fit together to complete coal combustion process, requires a lot of air and the furnace wall due to the leakage of flue excess air ratio of up to between 2.1-2.5. Micro-condensing gas boiler combustion positive or slightly negative pressure, a small amount of wind required, air is preferably premixed with the gas within the combustor. No leakage factor positive pressure combustion furnace flue wall and running flue outlet air coefficient can be 1.05-1.2.4 fuel combustion safety explosion-fired boilers, furnace explosion hazard unlikely to occur. The condensing gas boilers in the explosive concentration limits encountered fire will explode. More dangerous. The boiler control due to coal fired boiler, material thickness, amount of the blowing, the amount of the wind, the wind mixture ratio of coal and other reasons, to be automatically adjusted according to load difficult boiler operating parameters. And condensing gas boiler is less impact on the factors may be adjusted according to the size of the burner valve load, easy to achieve automatic control.
Gas boiler market prospects of geometry: divided by fuel coal, fuel (gas), electric steam furnace. Fuel oil (heavy oil and light oil is divided) gas (divided city gas and natural gas) 0.7mw-70mw china brown coal hot water boilers that burn oil or gas fired boilers can heat the water. Development of sub-pot boiler and furnace two aspects.
Recently biomass fired CFB boiler technology is spread increase quickly in Europe.CFB boiler technology can also can be called clean coal technology,which can make industrial boiler more efficiently and environment friendly.CFB boiler can burning biomass or coal as fuel to produce steam or hot water whatever you need.
