Performance of Coal Fired Boilers
- Single return thread fireworks tube is adopted in the boiler barrel of 20-ton coal fired steam boiler, with good thermal conductivity.
- The flue gas flows smoothly into the front smoke box after passing through the two wings of the flue gas, effectively reducing the flue gas temperature of the tube plate in the low-temperature zone, and preventing the generation of tube plate cracks and pipe explosion disorder.
- Adopt the strong radiation furnace arch, according to different fuel plan furnace arch, make the front arch and back arch phase response, form “” flame extinguish, easy to burn, and improve the level of burning fuel, deal with the poor coal extinguish performance, make the coal more adaptable.
- Compact structure, small floor area, single layer layout of boiler room, provincial capital construction investment; High degree of assembly, short installation cycle, less installation costs.
- The heating surface layout is sufficient and reasonable, the boiler temperature rise, pressure boost fast, full output, high thermal efficiency.
- The grate is divided into air bins and the air volume of each bin is independently adjustable, and the grate is stepless speed regulating, which is suitable for wide types of coal and full combustion.
- The electric control cabinet is equipped with complete automatic control and monitoring standard, with high degree of automation, safety and reliability, and easy operation.
- The boiler belongs to the whole water pipe structure, long life, radiation heating, high efficiency, environmental protection and energy saving.
