DZH coal fired moving grate boiler is single drum boiler with both water tube and fire tube, the combustion equipment is moving grate. Water wall tubes at left and right sides of furnace are the radiated heating area. the two wings at furnace and spirally corrugated tubes in the drum are convection heating area. This coal fired moving grate boiler uses the upper drum, water wall tube and head are in symmetrical arrangement mode. The furnace structure is in reasonable arrangement to achieve high efficiency.
1.Features Of DZH Coal Fired Steam Boiler
- 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 for boiler.
- Few moving parts, less investment, low operating costs, low maintenance costs.
- Forced ventilation, pressure boost fast to make sure enough output.
- Boiler is compact structure, easy to install, reducing the cost of the boiler room and installation cost.
- Steam boiler is single drum design big water volume, ability to adapt to changes in load.
- Sufficient combustion, large heating surface, boiler adopt efficient threaded pipe, so the boiler thermal efficiency higher than the national standard.
