The "Investa" boiler has a steam production capacity of 20 tons per hour, an operating pressure of 3.9 MPa, and a superheated steam temperature of 440°C.
It is a two-drum vertical water-tube boiler with natural circulation, a prismatic furnace, a three-pass convection bundle in the gas flow path, and sequentially installed downpipes.
The boiler reconstruction includes the installation of new straight-flow grates for burning bituminous coal of the GM 13-25 grade.
Technical specifications of the boiler after reconstruction:
- Steam production capacity: 20 tons per hour
- Operating pressure: 3.9 MPa
- Superheated steam temperature: 440°C
