Introduction
Coal Fired Boiler
Certified by ASME, CE, ISO, EAC, DOSH, TUV, BUV, ensuring high quality and compliance with international standards.
Popular model: DZL coal fired boiler automatical chain grate coal boiler
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.
Coal Fired 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.
Compare Manual & Automatic Boiler
DZH series is kind of manual coal feeding boiler, DZL series is kind of automatic coal feeding boiler.
