The boiler has a steam production capacity of 50 tons per hour, is a water-tube, single-drum boiler with natural circulation in a U-shaped layout, and is designed to produce superheated steam at a temperature of 440˚C and a pressure of 3.9 MPa.
The boiler reconstruction involves converting the unit to pulverized coal combustion using coal grades G and D. This includes the installation of new burner devices, a coal pulverizing system, and flue gas cleaning, control, and protection systems.
Technical specifications of the boiler after reconstruction:
- Steam production capacity: 40 tons per hour
- Operating pressure: 3.9 MPa
- Superheated steam temperature: 440˚C
