Product structure and delivery set
The boiler consists of:
- drum;
- front cover;
- back cover;
- burners;
- water treatment unit with make - up pumps;
- level sensor;
- control box;
- safety valves;
- steam collector;
- level indicator;
- instrument panel;
- frames with supports.
The technological process of vaporization is as follows:
Flue gases passing through the gas path of the boiler heat up its heat exchange surfaces. Water entering through the water treatment unit enters the boiler, where it is heated by heat exchange surfaces and evaporates. The steam passing through the superheater is superheated by the flue gases and goes to the consumer. The slags formed during the evaporation of water are periodically removed from the boiler by blowing. Boiler control and control over the technological process of vaporization is carried out using electrical equipment.
