Introduction
Coal Hot Water Boiler
Certified by ASME, CE, ISO, EAC, DOSH, TUV, BUV, ensuring high quality and compliance with international standards.
Most Popular model: DZL coal heating boiler automatic chain grate 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.
Themal Capaity in 0.7MW-28MW Automatic Coal Heating 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.
DZH Manual Feeding Coal Boiler
DZH series is kind of manual coal feeding boiler, need labor works to feeding coal into stoker.
Product: Small Coal Fired Boiler
Small coal hot water boiler in 41kw-1400kw.
Product: Water Tube Coal Boiler
SZL Series water tube coal boiler 2ton-50ton/hour.
DZL Boiler Features
Chain grate
Auto-feeding type burning system, avoid problem of air leakage, fuel leakage and uneven ventilation. Easier operation compared to traditional grate.
Water Softener
A complete water treatment system is included to remove hardness and prevent scale formation, protecting the boiler and improving efficiency.
Security guaranteed & Automation
Multiple safety and monitoring devices — pressure gauge, water level gauge, temperature sensor, and automatic safety protection system — ensure safe and reliable operation.
Economizer for Energy Saving
Equipped with a high-efficiency economizer to utilize waste heat from flue gas, reduce fuel consumption, and improve overall thermal efficiency.Technical Parameter
