1. 85T/H bituminous coal/anthracite/lignite fired CFB boiler: The boiler is a new kind mixed fuel boiler with high efficiency and low pollution, it adopts circulating fluidized bed combustion technology with wide range of many kinds of fuel, such as bituminous coal, anthracite, lignite and others with lower calorific value. Its combustion efficiency is as high as 95-99%, especially it can burn high sulfur-bearing fuel. By feeding limestone into the boiler, it can obviously reduce the discharge of sulfur dioxide and NOx, and reduce corrosion of sulfur on devices and pollution of flue gas. Ash residue is active enough to be used as aggregate of materials such as cement.
2. 85T/H bituminous coal/anthracite/lignite fired CFB boiler arrangement:
The boiler is a natural circulating water-tube boiler and adopts circulating combustion system formed by vortex cyclone separator. Its furnace is of membrane wall structure, its separator is of high-temperature adiabatic type. The superheater system is composed of screen, high and low temperature ones, between which two-grade vertical spray desuperheater is arranged. At the back-end surfaces, two grades of economizer, primary and secondary air preheaters are arranged.
The boiler is designed into indoor or outdoor type. If it is erected outdoor, the boiler will be redesigned with necessary rainshed. The operating floor elevation is 7.5 m and the boiler elevation is based on the zero-meter layer. The boiler steel structure is of all metal structure. When it is operated at areas where earthquake magnitude is over 7, reinforcement for the boiler steel structure is needed.

4. Company introduction: Established in 1954, Jinan Boiler Group Co., Ltd. ( Hereinafter called "JBG" ) is a large backbone company that manufactures Grade "A" power boilers and industrial boilers in China, and is also one of the leading companies for CFB boiler and biomass boilers. With the total asset value being over RMB 3 billion, JBG has 1500 employees, including 460 engineering technical staff. Located in the famous historical and cultural city -Jinan, the capital of Shandong Province, which is called "City of Springs", JBG covers an area of 320,000 square meters. Majoring in the manufacture of power boilers and industrial boilers, JBG integrates the research & design, manufacture, auxiliaries supply, installation, maintenance, alteration, power plant EPC, environmental project EPC and technology consultation.
Adhering to the business principle "dedicating clean energy, making green products, improving economic benefit and building harmonious enterprise", JBG develops the first circulating fluidized bed power boiler in China, introduces and digests the 100% biomass power boiler technology and manufactures the first 30MW biomass power boiler in China. Now, JBG has grown up to be a globally-known CFB (Circulating Fluidized Bed) boiler research base and the largest biomass fired boiler manufacture base, and JBG is one of high-tech enterprises in Shandong Provence and recognized as an experimental base by the Thermophysics Institute of China Academy of Science. JBG positively follows the low carbon economy trend and development of new energy industry and vigorously develops CFB boilers, biomass power boilers etc. for energy conservation and environmental protection. Now, JBG has developed more than 10 series and 100 types of products including CFB boilers, biomass boilers, pulverized-coal fired boilers, hot water boilers, waste heat recovery boilers, chemical recovery boilers, oil/gas fired boilers, waste incineration boilers, De-Sox & De-NOx products and pressure vessels etc.. The products are popular in China and exported to many countries, including Japan, Belgium, Singapore, Indonesia, Malaysia, Thailand, Pakistan, India, Viet Nam, Cambodia, Mongolia, Nigeria, Rwanda etc.
