Minimum air amount and the relationship between the excess air coefficient in the dew point of the flue gas for complete combustion of the fuel required under ideal conditions, said theoretical combustion air amount, the fuel for complete combustion in the actual conditions of incomplete combustion, or the actual amount of air required amount of combustion air . Excess air coefficient = actual combustion air amount / theoretical combustion air amount. Dew point (Dewpoint), also known as the dew point temperature (Dewpointtemperature), in meteorology fixing means under pressure, gaseous water contained in the air is condensed into liquid water saturation dropped to desired temperature. At this temperature, condensed water mist floating in the air is called, while the stick is called on a solid surface exposed, hence the name dew point. Excess air and flue gas dew point relationship when there is insufficient combustion air ratio of the fuel is not sufficiently low combustion efficiency, boiler efficiency is also reduced. When the excess air, the flue gas water vapor partial pressure decreases, the dew point temperature is low, it can not lead to condensation, latent heat can not be released, and the excess air factor will take a lot of heat, so that the boiler efficiency decreases. Therefore, when an excess air ratio of 1.2 to 1.3, to achieve complete combustion in the excess air coefficient is very small, almost chemically incomplete combustion phenomenon. When the air excess factor is 1.2-1.3, both to ensure that the dew point will not be too low (the condensation effect is very significant), but will not take away the excess air ratio in the flue gas waste heat large, which can greatly enhance the thermal efficiency of the boiler .
2019 Nanyang thermal efficiency steam boiler will be a kind of innovation to change? This boiler equipment, long before that became many places to use the equipment, such equipment, mainly can be used for heating and hot water, and so on. So boiler equipment, is to become a factory which will use the equipment, but are now starting to appear a steam boiler, are some of the common equipment in the factory.
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.
