Main features of coal fired steam boiler:

1. Moving grate made of cast iron, large furnace design, manual stoker, good applicability of fuel, coal, wood, wood waste, biomass, etc. can be used as fuel.

2. Few moving parts, less investment, low operating costs, low maintenance costs.

3. Forced ventilation, pressure boost fast to make sure enough output.

4. Compact structure, easy to install, reducing the cost of the boiler room and installation cost.

5. Single drum design big water volume, ability to adapt to changes in load.

6. Sufficient combustion, large heating surface, adopt efficient threaded pipe, thermal efficiency higher than the national standard.

Application for biomass steam boiler

Coal fired steam boiler is widely used in hospitals, schools, textile mills, garment factories, large supermarket, garment factories, dyeing factory, hotel, dining room, restaurant, food factory, beverage factory, soy products, meat products factory, cannery, brewery, pharmaceutical factory, packaging plant, building materials factory, paint factory, swimming pool and other places of the enterprises and institutions.
