What are the types of waste heat boilers?

Waste heat boilers are divided into the following categories:
1. According to the heating mode, there are water-pipe waste heat boiler and flue-pipe waste heat boiler.
2. Water-pipe waste heat boiler: refers to the flue gas convection outside the tube to wash water in the heating pipe.
3. Flue-tube waste heat boiler: refers to the flue gas passing through the tube and heating water outside the tube.
4. According to the circulation mode, there are natural circulation waste heat boiler and forced circulation waste heat boiler.
5. According to the layout, there are tunnel vertical waste heat boiler and horizontal waste heat boiler.
6. According to the degree of assembly, there are fast-loading waste heat boilers, modular (semi-assembly) waste heat boilers and bulk waste heat boilers.
7. Pressure points: low-pressure waste heat boiler and medium-pressure waste heat boiler.
8. According to system pressure, there are single-pressure waste heat boiler and double-pressure waste heat boiler.
9. According to flue gas pressure, there are micro-positive pressure waste heat boiler and micro-negative pressure waste heat boiler.
10. According to the amount of boiler evaporation, there are large waste heat boilers, medium-sized waste heat boilers and small-sized waste heat boilers.
