Coal-fired boilers of more than 20 tons are used to heat asphalt and crude oil

2023-10-16 08:51:57

 Different asphalt and crude oil have different softening points. If the heating temperature is too high, it will affect the penetration and elongation of the asphalt. According to the different use requirements, it is enough to heat the asphalt and crude oil to above the softening point to meet the appropriate fluidity. .At the same time, the flash points and autoignition points of different asphalts and crude oils should be considered to ensure safety.

Tracing asphalt and crude oil requires the use of steam boilers, and coal-fired boilers that are more cost-effective as fuels are the first choice. The following is an introduction to coal-fired boilers of more than 20 tons for asphalt and crude oil tracing.

Coal-fired boilers

Coal-fired boilers

1. 20-170 steam tons DHL corner tube chain grate boiler

DHL angle tube chain furnace is the latest replacement product for large capacity hot water boilers in my country. It adopts three invention patents and two utility model patent technologies such as "fly ash internal circulation fluidized recombustion device based on high temperature separation". It has the advantages of high thermal efficiency, low operating cost, low investment and long operating time.

2. 20-35 steam tons SHL chain grate boiler

The basic structure of the furnace is composed of upper drum, lower drum, water-cooled wall, convection tube bundle, economizer, air preheater and other components. It adopts the latest combustion theory achievements of Xi'an Jiaotong University and the latest development technology of boilers. It has sufficient output, High thermal efficiency, stable and reliable operation.

3. ≥20 steam tons SHW reciprocating grate boiler

This type of furnace is different from the previous chain furnace. It is a reciprocating furnace jointly developed by ZBG Group and Harbin Institute of Technology. The capacity per steam ton (0.7MW) can ensure the heating demand of residential buildings with a building area of ​​more than 12,000 square meters. It is widely used in many fields and industries such as pharmaceuticals, chemicals, food, metallurgical machinery, and mining.
