fix grate coal fired boilers
Lignite Power Plant CFB Boiler in Turkey
The size of CFB’s designed for lignite coal as primary fuel can vary in a broad range of steam capacity,from industrial to large-scale utility boilers.Additionally, many of the CFB power plant boilers designed for coal feature the well-known fuel flexibility capability adding fuels such as biomass and various types of waste which are co-fired simultaneously.
Coal-fired fix grate coal fired boilers to gas boiler advantages: China's major coal-fired boilers used to be the life of heating and industrial boilers being used. Total annual use of coal because coal-fired boilers consumed 600 million tons. According to incomplete statistics, China's total industrial coal-fired boilers is 60 million units. Visible large proportion of coal-fired boilers in China's industrial life, the breadth of coverage. The thermal efficiency of the boiler runs produced generally much lower than the gas boiler, emissions has doubled. Therefore, the transformation of coal-fired boilers to gas-fired boiler is imperative. From central to local government organs at all levels to join all the positive trend of the gas boiler of them, in order to reduce emissions, improve production efficiency to do their part.
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.
What are the common type gas steam fix grate coal fired boilers have? Common types of gas steam boiler is as follows: fuel (gas) is oil or gas as fuel, burning the fuel using a burner to heat the gas as steam carrier. Structure is generally divided into two kinds of vertical, horizontal, mainly based on these two forms of device space height. Gas based on coal as fuel, gas and steam as a heat carrier. Hand generally divided into vertical burn, horizontal cylindrical type, three kinds of gas fired horizontal plane structure, mainly based on labor intensity stoker thereby form these three points. For electric heating electric heating oil furnace, heat is generated and transmitted by the electrical heating element is immersed in the gas and steam to steam gas medium by the circulation pump to force liquid recycle gas steam, with a heat transfer to or more heating equipment, heating equipment after unloading, re-circulation pump, back to the heater, and then absorb heat, heat transferred to the device, again and again, to achieve a continuous heat transfer the temperature of the heated object rises, the heating to achieve process requirements.
