What is an CFBC boiler?
Circulating Fluidized Bed Combustion(CFBC) Boiler is an environment-friendly power facility to reduce the discharge of pollutants such as nitrogen oxide and sulfur oxide by injecting air and lime at the same time for burning.
What are the major performance features of CFBC boiler?
The major performance features of the CFBC boiler (circulating fluidizing bed combustion boiler) are: a) It has a high processing capacity because of the high gas velocity through the system.
What is the principle of FBC?
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.)
What is the difference between Afbc and CFBC boiler?
AFBC means atmospheric fluidized bed combustion, where the furnace pressure is atmospheric pressure. 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.

What is fluidized bed boiler?
A bubbling fluidized bed (BFB) boiler is a boiler that can also handle fuels that are difficult to pulverize or less combustible. The fuel is introduced into a mixture of sand flowing at high temperatures, allowing the fuel to be efficiently combusted.
What is CFBC technology?
It is the boiler that uses a specific technology called ‘Circulating Fluidized Bed Combustion (CFBC)’. The high concentration of bed material along with staged air supply ensures that bulk combustion temperatures do not exceed 950°C making it environment friendly (lesser production of NOx) means of utilizing coal.

How does a fluidized bed work?
Typically, pressurized gas or liquid enters the fluidised bed vessel through numerous holes via a plate known as a distributor plate, located at the bottom of the fluidised bed. The fluid flows upward through the bed, causing the solid particles to be suspended.
Where is the economiser located in a CFBC boiler?
Economiser is located in between SSH outlet and Air Pre-heater. Feed water flows from the bottom header to the top headers through these coils. Heated water flows out from the top header to steam drum through the connecting pipe. The economiser is provided with drain valves located on the inlet header. trapped between the coils.
What is the fuel value of a CFB boiler?
Typical gross heating values of some common fuels (based upon approximately 80% fuel to steam efficiency) are listed below: • Petroleum coke = 11,500 to 15,000 BTU/lb. • Anthracite coal ≈ 14,000 BTU/lb. Petroleum coke-fired CFB boilers in Europe.
How is petroleum coke used in a boiler?
Petroleum coke can be produced in the final stages of an oil refinery by the delayed coking process [l]. Petroleum coke can be used as carbonaceous materials 121, and as a fuel in utility boilers because of its high calorific value [3, 41.
How much steam is produced per ton of bagasse?
If the fuel is bagasse then the quantity of steam in tons generated per ton of cane crushed is given by. y = x · (F%C Steam produced per ton of bagasse was found to be 2.20 tons for 23 kg/cm2 pressure and 350 °C temperatures.
