Difference Between AFBC Boiler and CFBC Boiler, AFBC

AFBC is atmospheric fluidized bed combustion, where the furnace pressure is atmospheric pressure.The flue gas from the furnace goes through a cyclone and is let out to the atmosphere. As for CFBC, circulating fluidized bed combustion, the furnace is pressurized and the furnace gas is recirculated to capture the unburnt carbon, to increase the thermal efficiency of the boiler.

• Continued heating creates steam bubbles in the front tubes, which are naturally separated from the hot water in the steam drum, and are taken off. However, when the pressure in the water-tube boiler is increased, the difference between the densities of the water and saturated steam falls, consequently less circulation occurs.

What is flue Draught? - AskingLot.com

The difference between atmospheric pressure and the pressure existing in the furnace or flue gas passage of a boiler is termed as draft. Draft can also be referred to as the difference in pressure in the combustion chamber area which results in the motion of the flue gases and the air flow.

Difference Between Low- and High-Pressure Boilers | Hunker

A boiler is an appliance designed to heat water and produce energy. The heat is applied to water in an enclosed container before being distributed throughout the system. The major difference between a low-pressure and a high-pressure boiler is the amount of pressure per square inch and pounds per square inch gauge that the boiler produces.

Draft (boiler) - Wikipedia

The difference between atmospheric pressure and the pressure existing in the furnace or flue gas passage of a boiler is termed as draft. Draft can also be referred to as the difference in pressure in the combustion chamber area which results in the motion of the flue gases and the air flow.

Working of Boiler – Explanation, Parts, Working Principle

The boiler is a closed vessel, where the water is stored. Hot gases are formed by burning fuel in the furnace. These gases are made to come in contact with the water vessel, the point where the heat transfer takes place between the steam and water. Thus, the boiler's basic principle is to convert water into steam with heat energy.
