High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ and reduce heat lost.Sufficient steam storage room and heating area to generate high quality steam and high thermal power.Condenser is added to recycle the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce flue gas emission temperature and increase the thermal efficiency over 98% and save operating cost.

Environmental protection

Big combustion chamber equipped with Low emission combustion burner effectively reduce the NOx to 30mg/m3. Smoke duct and smoke outlet use internal insulation to reduce operating noise.

Combustion chamber uses full membrane water cooling wall structure and pressurized combustion without smoke mixture.

Energy conservation

Good quality alumina silicate fiber and fire clay insulation material are used and the boiler body temperature is controlled below 45℃ and greatly heat loss is reduced. Combustion chamber is designed with narrow distance tube membrane water cooling wall which has good air proof to reduce heat lost and increase boiler thermal efficiency. Internal inspection holes uses high-alumina refractory and manhole cover seal devices, solving superheat problem in this part caused by using refractory bricks.

CNC manufacturing technology

The key processing technologies such as steel plate blanking, circling, drum and tube plate drilling adopt advanced CNC machining to reduce the assembly stress and prolong the service life of the boiler.

Steel tube cutting, thread tube pressing and convection tube processing all adopt advanced CNC technology.

Automatic production line.

Fluidized bed combustion - Wikiped

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.

Comparison of Circulating Fluidized Bed Boiler an

The key differences of the CFB boiler with the universally accepted Pulverised coal firing is discussed in this article. Comparison of Circulating Fluidized Bed Boiler and Pulverized Coal Boiler. The diagrams below indicate the overall difference between the CFB boiler and the PC boiler systems.

what is afbc and cfbc boiler – CFBC Boiler Manufactur

CFB boiler is circulating fluidized bed boiler and afbc is atmospheric fluidized bed boiler. C refers to combustion process. I understand that afbc in common parlance is referred to stationary or bubbling fluidized boiler though technically it is correct to refer as stationary fluidized bed boiler.

Hamada Boil

Based on those data, and looking at the general behavior of coal and ash during combustion in bubbling fluidized bed, it is possible to define concept of the BFBC boiler, to choose main parameters and to calculate dimenssions of the furnace and capacity and dimensions of all auxiliary systems [11,12,16].

Fluidized bed combustion - COALsp

Fluidized bed combustion (FBC) is a combustion technology used in power plants. FBC plants are more flexible than combustion, which also allows more efficient heat transfer from the boiler to the apparatus used to capture the heat energy bubbling or circulating fluidized bed (BFB or CFB).

Circulating fluidized bed combustion (CFBC) - ScienceDire

History and current status of circulating fluidized bed combustion (CFBC) technology In comparison to bubbling fluidized bed (BFB) boilers, CFB boilers give lower NO x emissions burning similar fuels because of inherent differences in the contacting pattern Circulating fluidized bed (CFB) boiler process and performance.

What is the difference between an AFBC and CFBC boile

CFB boiler is circulating fluidized bed boiler and afbc is atmospheric fluidized bed boiler. C refers to combustion process. I understand that afbc in common parlance is referred to stationary or bubbling fluidized boiler though technically it is correct to refer as stationary fluidized bed boiler

How Circulating Fluidized Bed Boilers Wor

Circulating Fluidized Bed (CFB) combustion boilers gives the flexibility for combustion of a wide range of coals and alternative fuel sources. All this without compromising efficiency and with reduced emissions. This article gives a brief description of the working of a CFB boiler. At the bottom of the boiler furnace there is a bed of inert material.
