cfb ash utilization boiler surfur

Large volume of combustion chamber. Large volume design can meet a variety of needs. In order to obtain low thermal load, the cfb ash utilization boiler surfur chamber with a large capacity can guarantee the full combustion of the gas or liquid fuel. the temperature can be spread evenly so as to avoid the blocking and protect the tube and the baffle.

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.

Secondly, modular cfb ash utilization boiler surfurs with a general volume is very small, fast boiler produced one ton of hot water boiler, the minimum volume of 1.2 cubic meters, demand is not high on the boiler room, basement, semi-basement, the ground can be, and the boiler room area is also very small, more suitable for the high cost of urban centers.

10tph WNS series energy-saving gas-fired steam cfb ash utilization boiler surfur for the textile industry

Changshu Hongda Textile Printing & Dyeing Co., Ltd. was founded in 1984. With strong technology strength, the company is engaged in the production and sales of cotton, rayon, ramie cotton fabrics, silk fabrics, cotton knitted fabrics, etc. As an export-oriented enterprise, the company exports products to America, Japan, Canada, Germany, Australia, Korea, the Middle East, etc. The production processes such as printing, dyeing and finishing require a large amount of steam. Therefore, a set of energy-saving and high-efficient steam boiler is very important for the textile enterprises.

Fluidized bed combustion - Wikipedia

Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels.. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials (sand, limestone etc.) through which jets of air are blown to provide the oxygen required for combustion or gasification.
