Poor atomization of oil - Just as fuel-rich mixtures could allow accumulation of unburned combustibles, any inventory of a combustible fuel in the furnace can result in an explosion. Boilers are blown up every year as a result of poor atomization of oil which results in incomplete combustion and can lead to unburned oil puddling on the floor of the furnace.

Boiler Operations That Affect Efficiency (Part 2)

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).

Low Fuel Oil Temperature Effects on Boiler Operation - …

13/1/2010 · Irrespective of whether fuel oil is used for load carrying or as support for fuel in a boiler, it is very important to maintain the fuel oil temperature as the amount of unburned fuel collection over a period of time can explode the boiler or lead to air pre-heater fires. Both of this lead to a long outage of the boiler and a loss of production.
