Boilers & District Heating
Retubing, cleaning and leak detection of heat exchangers at combined heat and power plants and heating boiler plants.
Common issues in boiler and heating plants
- Scale. Scale on the inside of water-tube and fire-tube boiler tubes cuts heat transfer and has to be cleaned out.
- Leaks. Vacuum leak testing of the tubes and the tube-to-tubesheet joints pinpoints where a leak is.
- Retubing. Overhauls and retubes are usually scheduled before or after the heating season.
