Boilers are heat exchangers in which the water heating process takes place by burning fuel and thus the water is transformed in heat agent: warm water (temperature up to 115°C), hot water (temperature over 115°C), saturated or overheated steam.
Warm water boilers produce heat agent required for heating and hot water, with the following characteristics:
– capacity: 0,2Gcal/h – 10Gcal/h;
– pressure: max 10bar;
– temperature: 70/90(70/115)°C.
Hot water boilers – ensure heat agent required by technological process and heating of industrial facilities, with the following characteristics:
– capacity: 0,2Gcal/h – 10Gcal/h;
– pressure: max 20bar;
– temperature: 70/150(70/130)°C.
Steam boilers – provide steam for various processes (0,1 ÷ 30t/h).
Classification:
- boilers for low pressure saturated steam – max. 0,7bar;
- boilers for medium pressure saturated steam – max. 0,7bar – 15bar;
- boilers for high pressure saturated steam – 15bar;
- overheated steam boilers;
- energy steam boilers.
