AFBC boiler is a very developing technology now these days this technology is widely used in the industrial boiler for the purpose of efficient and clean burning of coal and other fuel for steam generation. AFBC boiler is suitable for combustion of low quality fuel . In AFBC boiler fluidization bed combustion is method of burning of solids fuel

AFBC BOILER HOT/WARM STARTUP PROCEDURE the power sector boiler may be tripped due to lots of resins like plant black out (grid supply goes ), any pump , fan , drive , tube punctured or other electrically or mechanically issues .

In cfbc boiler fuel system like a very important funtion of in all process. fuel feeding have two types one is over beding system and other one is under bed system.In over bed system coal is

AFBC Boiler Working Principle: Technological collaboration with Power Systems for boilers up to 300 TPH. There are more than AFBC boilers operating worldwide which were designed as per Power System design and supplied either directly produced by their licensees. AFBC Boiler Salient Features: Low fluidizing velocity for lower wear of bed tubes.

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. Bed is where the coal or fuel spreads. Air

Afbc is air fluidized bed combustion boiler . this type of boiler the bed is having pa ( primary air nozzles) through which air passes and burn the fuel which is present on the bed . basically light density fuel is used for this type of boiler. Ef

Jan 27, 2018· Short answer : AFBC = Atmospheric (Bubbling) Fluidized Bed Combustion CFBC = Circulating Fluidized Bed Combustion Long Answer: It is just a way of burning of a fuel. for example a Travelling Grate Stoker burn the fuel in Static Mode such that fuel

afbc boiler for multifuel feeding addition that there is one cyclone is for collecting escaped coal particles and again feeding into the furnace.. Karnataka State having capacity 90 TPH at 72 Kg/cm2 at 510ºC with multifuel . lexie@zozen.com > Get A Quote >

Dec 11, 2015· Difference Between CFBC & AFBC CFBC boiler Flue gas velocity-3.7 to 4.3 m/sec Over bed feeding U beam Technology No bed coil UBC-Less than 2% Efficiency high (88%) Clinker formation chances low Tube erosion high as compared to AFBC Ash recycle (unburned heavy particle) system. Fuel consumption is less as compared to AFBC AFBC boiler Flue gas

CFBC boiler stands for circulating fluidized bed combustion boiler, the furnace is pressurised and the furnace gas is recirculated to capture the unburnt carbon, to increase the thermal efficiency of the boiler. Hence this is an improved version of AFBC. The CFBC boiler has more advantages than AFBC boiler. a. High efficiency.
