Technical fuel is used for production power plants and industrial furnaces heating. It includes high-grade fuel in various aggregate states: coke, combustible gases, metallurgical coals, masut, etc.
Technical fuel is not produced according to GOST, but according to the technical specification, therefore its composition and properties directly depend on the manufacturer. The main requirements for such fuels are as follows:
- high heat transfer coefficient,
- minimal presence of water and sulfur compounds,
- safe and complete combustion without harmful emissions,
- low production and transportation price.
Technical fuel types
For production processes, the following types of fuel are used: natural and artificial. Natural fuel is extracted on the earth surface and in the subsoil and is ready-for-use: firewood, coal, natural gas, etc. Artificial fuel is produced by processing natural fuel: coke, fuel oil, kerosene, liquefied gas.
The most popular artificial type of fuel is technical fuel type C (TTC). It is a transparent combustible liquid, which has various color variants – from pale yellow to dark brown. Depending on the manufacturer, this technical fuel may also be called ship’s or stove fuel. Characteristics of such fuel produced by individual specifications are often different, so when you purchase it, you need to carefully examine the quality certificate.
Standard TTS is a fuel with the following properties:
- density – an average of 840 kg / cu. m.,
- ash content – up to 0.02%,
- sulfur content – no more than 0,5%,
- flash point is about 50 ° C,
- water content – up to 0.5%,
- set point – up to -15 ° C.
Technical fuel application:
1) for production cycles that require high-temperature conditions – cement production, foundries, ship power plants, etc.;
2) burning in industrial furnaces for the purpose for heating;
3) heating of residual oi masut, drying production components and raw materials, feeds preparation;
4) as a solvent for masut and dense hydrocarbon resins.
Technological fuel is not used for domestic needs.
