Introduction
Coal Hot Water Boiler
Popular model: DZL coal fired boiler, automatically chain grate stoker boiler.
1) DZL automatic coal boiler, with chain grate combustion device, adopt automatic coal feeding system, inner fire-tube & water-tube structure, wing-shape flue and flue gas three pass design, higher thermal efficiency than traditional manual coal boiler.
2) Available Fuel: coal, charcoal, briquette, biomass, wood, pellets, husk, solid fuel
Coal Boiler System
Complete boiler system need some other accessories for help boiler work successfully. Introduce some important accessories as following:
1. Water softener ②, Remove Mg+,Ca+ in the water and improve water quality, prevent hurt to boiler tube, entend the boiler using life time.
2. Economizer ⑧, use exhaust gas to heat inlet-water then reduce exhaust gas temperature, which improve boiler efficiency.
3. Dust collector ⑨, bag filter, Remove the dust and ash in exhaust gas to protect environment and reduce pollutions.
4. Forced fan & Induced fan ⑦, Blow clean air into the boiler and promote exhausted gas out, ensure the air circulation of the whole system.
