record fluidized bed boiler

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.

The welding of important parts like the vertical and circular seams of the boiler, the tubes, the inside of boiler and the flange are all adopted automated welding processes such as submerged arc welding or gas shielded welding to ensure the welding quality. All the vertical and circular seams will be done 100% radiographic inspection.
Tube flange weld adopts robot welding.
The chain grate panel, front and rear smoke chamber panel adopts CNC plasma cutting machine to cut orderly and beautifully.

Agglomeration in fluidized beds at high temperature

Fluidized-bed conversion of solid fuels is a well-established and widely used technology. Yet, operational problems are encountered in industrial practice. One of the most important problems is the occurrence of agglomeration at high temperature, meaning that bed particles adhere to each other to form larger entities (agglomerates).

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.

Sulphur capture in circulating fluidized-bed boilers: Ca

The presence of CaS in bed ashes from a circulating fluidized bed boiler (CFBB) has been studied. The boiler was operated with an excess air ratio of 1.2 but with varying air staging and at

Computational Fluid Dynamics (CFD) for fluidized be

fluidized bed boiler design and retrofits Challenges Today the goals typically are to meet new emission limits and to replace fossil fuels by bio fuels and waste. The increasing use of low quality fuels sets high demands on the understanding and control of the furnace processes in order to ensure satisfactory operation and furnace availability.

A sulphur capture model for circulating fluidized-bed boile

It has been shown that there is a considerable size decrease of sorbent particles in a fluidized-bed boiler (FBB) (Lyngfelt and Leckner, 1991). Thus, for modelling purposes, it is inappropriate to use the added size distribution of sorbent, while a more accurate distribution can be obtained from the exiting flows.

Circulating fluidized bed - Wikiped

The circulating fluidized bed (CFB) is a developing technology for coal combustion to achieve lower emission of pollutants. By using this technology, up to 95% of pollutants[1] can be absorbed before being emitted to the atmosphere.

Circulating Fluidized Bed Boiler | CFB Boiler | GE Pow

efficient circulating fluidized bed boiler combustion and fuel flexibility Our CFB boiler technology allows for a wide range of fuels to be burned efficiently. This includes low-grade and difficult-to-burn fuels such as anthracite, lignite, petroleum coke, oil shale, discarded coal, and biomass within a wide range of mixing rates.

The circulating fluidized bed (CFB) coal-fired boiler has being rapidly developed in China since 1980s and becomes a key clean coal technology used in thermal and power generation.

3-D full-loop simulation of an industrial-scal

Three-dimensional (3-D) simulations using an Eulerian multiphase model were employed to explore flow behaviors in a full-loop industrial-scale CFB boiler with and without fluidized-bed heat exchanger (FBHE), where three solids phases were employed to roughly represent the polydisperse behavior of particles.
