non ferrous metal roasting waste heat boiler
Boiler parameters "ZhengDun" What is the concept: tons of steam is an engineering term, refers to a level of the heating non ferrous metal roasting waste heat boiler, with a generally T / h is represented, the amount of steam boilers represent this produced per hour.
In conventional non ferrous metal roasting waste heat boilers, the exhaust gas temperature is generally 160 ~ 250 ℃, water vapor in the flue gas is still in a superheated state, it can not be condensed into liquid water and release latent heat of vaporization. As we all know, the thermal efficiency of the boiler low calorific value fuel is calculated without considering the heat loss of latent heat of vaporization of fuel in the high heating value. Thus the thermal efficiency of the conventional boiler generally only 87% to 91%, while the condensing heat recovery boiler, the exhaust gas temperature which is reduced to 50 ~ 70 ℃, full recovery of the latent heat of condensation and sensible heat in the flue gas water vapor.
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.
5, the fuel value of the product itself
Different fuels, different burner, combustion heat will cause the output value of the last changes. The higher the value of international standards based on combustion condensing boiler, use the more energy-efficient.
