Boiler Fuel Oil

Boiler fuel oil refers to a type of liquid fuel that is used in boilers and other industrial combustion systems to generate heat. It is commonly used for heating applications in various industries, including power generation, manufacturing, and residential heating. Boiler fuel oil is a dense and viscous liquid that is derived from crude oil through a refining process.

There are several grades or types of boiler fuel oil, which are classified based on their properties and intended use. The most common types of boiler fuel oil include:

Fuel Oil No. 1 (FO1): Also known as distillate fuel oil, this is a relatively light and clean fuel used in residential heating and small industrial boilers.
Fuel Oil No. 2 (FO2): This is a slightly heavier and less refined fuel than FO1, often used in larger industrial boilers, heating systems, and diesel engines.
Fuel Oil No. 4 (FO4): This is a heavier fuel oil used in industrial boilers and power generation. It requires preheating before it can be burned efficiently.
Fuel Oil No. 5 (FO5): A heavier and less refined fuel used in larger industrial boilers and power plants. Like FO4, it also requires preheating.
Fuel Oil No. 6 (FO6): The heaviest and least refined of the fuel oils, it is used in large industrial boilers and power plants. It requires substantial preheating and handling equipment due to its high viscosity.
Boiler fuel oil is stored in tanks and typically delivered to the combustion system through a system of pumps and pipes. It is sprayed or atomized into the combustion chamber where it mixes with air and ignites, producing heat. The heat generated is used to produce steam or hot water, which is then used for various heating and industrial processes.

It's worth noting that there is a growing interest in using alternative and more environmentally friendly fuels for boilers, such as natural gas, biofuels, and electric heating, to reduce greenhouse gas emissions and environmental impact.
