#4 fuel oil (bunker oil) is used in large stationary engines, power plants, and very large commercial boilers. No. 4 oil when burned as heating fuel may contain several contaminants including nickel and sulphur. No. 4 fuel oil is typically produced by blending distillate along with residual fuel oils such as No. 2 and No. 5.

Fuel oil components with low melting point form molten ash components and stick to the surface of boiler walls, superheaters, reheaters, and economizers. Growing deposits set a long sequence of compensation actions into gear. Heat transfer is reduced. The gas temperature needs to be raised to keep the steam quality constant.

Nov 09, 2018 · Why Use Heavy Fuel Oil? This heat energy is used in a boiler – cold water sitting in pipes is heated up until the water is boiled into steam. Besides the fuel used to power the plant, this steam is another important factor in the energy-creation process. In order to begin the actual electricity creation, this steam must turn the numerous
Read MoreNormally the heating is by way of steam produced by an oil-fired boiler and passed through coils inside the oil tank. Other ways to heat the fuel tanks are by using thermal oil. It also utilizes an oil fired boiler that heats the thermal oil, which is circulated through coils inside the tank by a pump.

heating systems in New York City. No. 4 oil is a mixture (50/50mix) of No. 2 heating oil and No. 6 residual fuel. Heavy residual oils are so viscous that they are solid at room temperature and must be kept in heated storage tanks. The distillate grades typically used in boilers include No. 2 fuel oil and No. 4 fuel oil.

Fuel oil is a fraction obtained from petroleum distillation, either as a distillate or a residue. Broadly speaking, fuel oil is any liquid petroleum product that is burned in a furnace or boiler for the generation of heat or used in an engine for the generation of power, except oils having a flash point of approximately 40 °C (104 °F) and oils burned in cotton or wool-wick

Residual fuel oil is one of the lowest-value petroleum products from a refinery. It is essentially a by-product of producing the light products that are the primary focus of a refinery. The primary end use for residual fuel oil is as a fuel in simple furnaces such as power plants and industrial boilers. It is also the primary fuel used on ocean

In April 2011, New York City (NYC) adopted a new heating oil regulation requiring owners of nearly 10,000 buildings to phase out the use of #6 and #4 heating oils. By July 2015, existing boilers must have been switched from burning #6 oil to a cleaner fuel before their current certificate to operate will be renewed.

Class D - Diesel or gas oil. Class E - Light fuel oil. Class F - Medium fuel oil. Class G - Heavy fuel oil. Oil began to challenge coal as the preferred boiler fuel in the UK during the 1950s. This came about in part from the then Ministry of Fuel and Power's sponsorship of research into improving boiler plant. The advantages of oil over coal
