DZH series boiler is manual operation boiler which adopting manual fuel feeding, manual slag removing. the fuel can be firewood, wood logs, biomass pellets, peanuts shell, grain shell, etc. Equipped with special dust collector solution (water film dust collector, bag type static electricity dust collector, double towers desulfurization, etc.), it can realize automatic fuel feeding, automatic ash removing. It is the most popular products in Southeast Asia, Central Asia, Africa.

this steam boiler fixed, moving grate two combustion methods, supporting auxiliary blowers, fan, power distribution cabinets, automatic water treatment, the series furnace affordable to meet the different needs of users.

It normally suitable for 1ton to 4ton/h capacity,use biomass pellet,wood pellet, wood chip, rice huskrice husk,straw, cashew, sawdust, paddy,peanut,palm oil kernel shell,cashew nut and all other kinds of solid fuel.  

Nude packing for boiler main part and wood box packing for boiler accessories. All goods will be reforced after packing. 20 or 40 flact container shipping.

Main features of coal fired steam boiler:

1. There are three coal feeding methods: hydraulic push, manual drive and chain drive.

2. Beautiful appearance: heat insulation material and high color board outer packing are adopted.Namely heat preservation and energy saving, and beautiful generous.

3. Simple operation: it can run for several hours at a time, and users can enjoy 24-hour heating as a power plant.

4. Energy-saving economy: reasonable structure, adiabatic combustion, high combustion efficiency, obvious energy saving, low fuel cost.

4. Saving investment: no investment of drum and induced draft fan, saving electricity cost, the products are fast installed and easy to install.

5. Environmental protection standards: the upper combustion mechanism design is adopted to meet the smoke emission standards of coal-fired boilers, which can be used in a class of environmental protection areas without disturbing the residents with noise.

Automatic control and fault protection of steam boiler

Boiler steam pressure automatic regulation system: boiler steam pressure automatic regulation system control system into the working state, in meeting the necessary conditions for combustion: when the steam pressure in the boiler is higher than or equal to the set pressure limit, the control system output stop signal.Until the induced draft fan is stopped.

Feed water automatic control: when the system is on duty and working normally, start the feed water pump, the water pump works, the water level differential pressure transmitter detects the water level signal, and keeps the water level of the pot stable.Ensure the quality of steam.the water level regulating instrument shows the boiler water level.

Manual control: the water pump can also be manually controlled by touching the key on the control panel.

Scope of application:
DZH type steam boiler is suitable for painting room, drying box, drying tower painting line and other purposes.It is especially suitable for central heating in urban residential areas, industrial production, enterprises and institutions, schools, hotels, bath centers and other places where heating, hot water and steam are needed.
