Oil/Gas Fired Boilers

Oil / Gas Fired Boilers are the basic 3 pass internal furnace smoke tube type design in which flue gases are inside the tubes while water is outside the tubes in the shell. The combustion of oil and gas in a furnace requires atomization of the fuel. Since the fuel entering the burner in bulk amount is either in liquid or gas form, therefore it needs to be separated in fine droplets so that every last particle of the fuel could get burnt without leaving any traces. This process of separating the fluid particles is called atomization. Generally, atomization is done with the help of high-pressure fan which also provides air for the combustion of fuel. Mostly burners come with the attached fan and their assembly is known as a Monobloc Burner which means fan mounted on a burner. The 3-pass oil/gas fired boilers are most suitable for the burn fuels like heavy and light oils & gasses.

Difference between Oil Fired Boiler and Gas Fired Boilers

Oil Fired Boilers generally require Day Oil Tank to store oil and this oil is transported to a burner through oil piping and oil pump. On the other hand, High-Efficiency Gas Fired Boilers are exactly same as Oil Fired Boilers in construction and only difference is the transportation of gas to burner requires gas train which comprises of gas regulator that regulates pressure, gas strainer to remover dirt from gas while no such valves are required in oil fired boilers
