The various types of industrial fuel oil are developed for the industry. They are the result of a complex combination of hydrocarbons produced by the distillation of crude oil for the production of heat in thermal plants. This fuel, of low sulphur content, can be used in heating or co-generation systems and low or medium speed engines.
The different types of existing fuel oil (N.º 3, N.º 4 ATE; Nº4 BTE and co-generation) are characterised by the different viscosities that regulate their use:
Ovens and furnaces
For use in heating of fluids and materials.
Caldeiras
Used to produce steam and hot water.
Stationary diesel engines
Can be used on existing co-generation installations and low or medium speed engines.
