Biomass Small Wood Pellet Coal Fired Steam Boiler
Coal fired CFB boiler technology:
In view of the possible near-term benefits, ZG recently funded an assessment of coal fired power plants equipped with three different combustion systems: Kinds of coal, Circulating Fluidized Bed (CFB), and biomass fired circulating fluidized bed. The purpose of this study was to establish, through engineering analysis, the most cost-effective performance potential available through improvement in the steam conditions and combustion systems.
Boiler for Rubber industry
Rubber Vulcanizing need high temperature steam, while steam generation is produced by steam boiler. In rubber industry, steam boiler play an important role which supply high temperature steam. Steam boiler fuel can be: Rice Husk, Coal, Lignite, Washery Rejects, Char, Indian/Imported Coal, Petcoke, Pith, Wood etc. Boiler prices for steam generation in rubber industry, please contact our online service, and we need to comfirm the capacity, pressure, temperature.
What is the main difference between a coal-fired boiler and a gas-fired biomass small wood pellet coal fired steam boiler? Nominally, the obvious difference between a gas-fired steam boiler and a coal-fired boiler is that the fuel used is different. The former uses natural gas and the latter uses coal. I think the misgivings of many boiler users are why they should eliminate coal-fired boilers because many have already purchased and used coal-fired boilers. If they switch to gas-fired boilers, it will be a huge expense. Firstly, according to the development direction of China's ecological environment, coal-fired boilers will gradually be replaced by gas-fired boilers or other clean and environmentally friendly energy boilers, and gradually withdraw from the historical stage. Yes. The difference between coal-fired boiler and gas-fired steam boiler is very big, and the main reason for eliminating coal-fired boiler is environmental protection. From the fuel supply part, the gas-fired boiler only needs a pipe to connect to the boiler; the coal-fired boiler requires coal yard, coal (belt or man-made), coal transport, loading and unloading, storage and boiler loading process. It will produce dust, causing serious pollution to people's living environment. From the point of view of atmospheric emissions, the content of dust in natural gas is very small and can be negligible; the ash content of coal is high, and the ash content is about 10% and 30%, which will produce smoke after combustion. If dust removal facilities are reduced, pollutant emissions will be reduced. It will increase; if there are more dust removal facilities, the corresponding costs will increase, which is not a long-term solution. In addition, the sulfur content of natural gas is also very small, coal-fired boiler dust removal, desulfurization and nitrogen removal can be obtained, gas-fired boilers only need to consider the problem of nitrogen removal. From the point of view of other waste emissions, natural gas is basically free of other pollutants, especially urban gas. In the case of coal, coal yards, especially small boilers built mainly in the open air, will produce coal slurry water during the rainy season, seeping into groundwater or sinks. When entering the surface water, the burning ashes are transported to produce dust. Of course, there's a difference in other ways. Different. For small-sized boilers, gas-fired boilers are more energy-saving than coal-fired boilers, with simple equipment flow, small footprint, low operating and maintenance costs, and so on. These are the main differences between coal-fired boilers and gas-fired steam boilers, and the significance of eliminating coal-fired boilers. It can be seen that the use of gas-fired boilers is the general trend of the whole society.
After years of efforts, the overall governance of Beijing's total coal consumption has achieved initial results. By the end of 2017, all of the total coal consumption of 4.85 million tons, accounting for only 5.6% of the city's total coal consumption, coal-fired completed three years ahead of "Thirteen Five" energy development plan period proposed control in less than five million tons The goal.
By 2013 to 2017 for five consecutive years to promote the work Yajian coal, Beijing successfully completed the first phase of the "Yajian based" Yajian coal work, go to "run mainly to protect", established clean energy use long-term mechanism to combat second phase coal-fired rebound. Beijing's total coal consumption in the future will be long-term control in less than 4.2 million tons, coal is mainly used for urban hazardous waste incineration, energy and protect the city safe operation of remote mountain villages Beijing winter heating three aspects.
As of last heating season, heating central heating proportion of clean energy in Beijing has reached 98%, in addition to parts of Pinggu and Yanqing, Miyun three zones as well as six coal-fired heating boiler room, other regions have achieved heating boilers no Coal.
This year, Beijing will complete the rural village 450 villages, the villagers coal public spaces and 53,000 square meters of agricultural facilities Zizhong change clean energy work, and strive to complete the Yanqing east of central heating central heating fuel in pre-season coal boiler clean energy transformation, in an orderly coal-fired heating center south of Yanqing, Pinggu Riverside, Xinggu, Miyun Taishi Tuen urban and non-built-up areas boiler clean energy transformation.
In addition, this year, Beijing Yanshan Petrochemical Industries will start coal-fired facilities clean energy transformation, and continue to consolidate six districts of the city, the southern plains "No Coal" results have been achieved on the area of clean energy transformation, embargo, ban, ban save bulk coal, to prevent rebound.
Speed up the construction of clean energy facilities, Beijing will work to enhance the rural town of Plains gas pipeline network construction, improve rural consumption of clean energy supply security capacity, promote Plains natural gas pipeline "through town." In the gas network facilities are relatively weak areas, speed up the liquefied natural gas, compressed natural gas supply facilities, increase the supply capacity of natural gas distribution in rural areas. At the same time, we continue to promote the 2018 "from coal to gas," "coal to electricity" supporting gas engineering and construction of power transmission project, to meet the full 2018-- coal to clean energy by 2019 energy demand for the heating season.
