Introduction
DZH Manual Coal Boiler
Certified by ASME, CE, ISO, EAC, DOSH, TUV, BV, ensuring high quality and compliance with international standards.
DZH series coal Boiler, is kind of manual type coal fired boiler, inner fire-tube & water-tube structure, wing-shape flue and flue gas three pass design, conbustion device is travelling grate.
Biggest advantages: DZH boiler has strong fuel adaptability for solid fuel: coal, wood log, wood chip, solid waste.
DZH Coal Boiler Features
1. Manual type coal/wood fired boiler, water-fire tubes & wing shape flue structure . Sufficient steam power, steady boiler running for 24 hours' work consistantly.
2. Using energy-saving device, eco-friendly emission strandard, low original dust discharge concentration, environmental protection and energy conservation.
3. High quality steam output boiler, equipped water treatment device and economizer devices. Long life span than 25Years, offer whole life service for boiler.
Compare Automactic & Manual Coal Boilers
1. Biggest difference is combustion device, thus cause different working way. DZL is automatic coal feeding boiler, DZH is manual hand operating coal boiler.
2. Different fuel adaptability, DZH boiler could burn biomass waste/wood log/wood chips with coal, stronger fuel adaptability than DZL boiler.
3. Different thermal efficiency, absolutely, DZL boiler has higher thermal efficiency compared with DZH boiler.
Product: Small Coal Boiler
Samll vertical coal boiler, with simple structure, in vertical type, steam or hot water heating boiler.
Capacity in 40kw to 1400kw, 200kg to 2000kg/hour.
DZH Boiler Features
Travelling grate boiler
DZH boiler use travelling grate combustion equipment. It needs labor hand feeding into coal/wood. It has advantages of low-failure rate, longer life span
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
