Introduction
> Industrial Coal Boiler
Certified by ASME, CE, ISO, EAC, DOSH, TUV, BV, ensuring high quality and compliance with international standards.
DZL series coal boiler - automatical chain grate coal boiler
DZL 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 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.
> Manual & Automatic Feeding Boiler
DZH series boiler, is manual feeding type boiler, using travelling grate stoker combustion,
DZL series boiler, is automatic coal feeding boiler. with chain grate stoker combustion.
> Product: Vertical Coal Boiler
Small coal-fired steam boiler, small coal-fired hot water boiler.
> Product: CFB Pulverised Coal Boiler
10ton-75ton CFB pulverised coal boiler, Circulating fluidized bed combustion technology, is kind of new and mature coal combustion clean technology, with high-efficiency, low-pollution.
DZL Boiler Features
Chain Grate / Reciprocating Grate
Fitted with either a chain grate or reciprocating grate, suitable for various types of solid fuels such as coal, biomass, or wood, ensuring full combustion and stable performance.
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
