Boiler. Boilers use the heat released during combustion to heat water or produce steam for heat supply or for driving a steam turbine, gas turbines or gas engines use gaseous energy carriers for generation of electricity and mechanical power, and internal combustion engines are used in vehicles (Sims, 2002).

Boiler Operations That Affect Efficiency. (Excerpted from Steam/its generation and use, 42nd edition) In its simplest form, efficiency is the ratio of energy output to energy input, expressed as a percentage. To optimize efficiency, therefore, it is important to minimize input (fuel being a major source) and maximize output (steam production).

Natural gas is used as fuel and the composition of the gas is traced daily. • Number 2 represents combustion air feed which takes place close to the burners. Combustion air is taken from the atmosphere by forced draft fan and sent to the boiler through the preheater.

Forced draft boilers run a positive pressure from overfire, through to the stack termination. The entire system must be welded or otherwise sealed tightly to prevent flue gases from escaping. Also, the height of the vent termination must be limited (generally 15 feet from the breech) to prevent a negative draft.

when gas firing or oil burner servicing is desired. Sealing air (aspirating air) is supplied from the forced draft fan or other source at a sufficiently high pressure to allow for safe removal of the oil burner or automatic gas lighter while the boiler is in service. Figure 11

Forced draft: Draft is obtained by forcing air into the furnace by means of a fan (FD fan) and ductwork. Air is often passed through an air heater; which, as the name suggests, heats the air going into the furnace in order to increase the overall efficiency of the boiler.
