Working Principle | Boilers Guide

Like other process furnace and direct-fired heater fireboxes, boiler fireboxes have a refractory lining, burners, a convection-type section, a radiant section, fans, air flow control, a stack, and dampers. The boiler firebox is insulated to reduce the loss of heat and enhance the heat energy being transferred to the boilers internal components.

DIFFERENCE BETWEEN ID FAN AND FD FAN - Mechanical

Before discussing the difference between ID Fan and FD fan, we must understand why we require draft system. Draft system is required for basically two purpose i.e. for providing the required quantity of hot air to furnace for smooth combustion of fuel and secondly for removing the flue gases from system i.e. furnace to atmosphere after filtering dust with the help of electrostatic precipitators.

How Power Plant Boiler Works? How Combustion System in

Jan 28, 2009 · This fan takes air from the atmosphere and blows it into the furnace through air ducts. The Air Heater heats the air before it enters the Furnace. Air Heater utilises the heat of the hot flue gases that leave the boiler to heat the combustion air. Hot air improves the efficiency of combustion. The Air Heater works on the regenerative principle.

The working principle of the boiler centrifugal induced draft fan is basically the same as that of the turbo compressor, except that the gas flow rate is low and the pressure does not change much. Normally, it is not necessary to consider the change of the specific volume of the gas, that is, to treat the gas as an incompressible fluid.

These fans are located at the inlet of the boiler to push high pressure fresh air into combustion chamber, where it mixes with the fuel to produce positive pressure. The most common centrifugal fans used as FD fans are backward curved and airfoil centrifugal fans. In power plants, where coal is used as fuel for combustion, FD fans are used as
