DZH coal/ biomass smal pellet boiler realizes zero pollution with the use of special dust collector solution (water film dust collector; bag type static electricity dust collector; double towers desulfurization, etc.). Because its steady performance and low fuel consumption, make it is popular in market
1.Model:DZH

3.Design pressure:0.7Mpa(7bar), 1.0Mpa(10bar), 1.25Mpa(13bar),1.6Mpa(16bar)
4.Stem temperature: 184 °c,194°c, 204°c
5.Design fuel: Biomass pellet,wood sawdust, bamboo chip, wood block, straw
6.Structure: horizontal water-fire tube, single drum
7.Type: DZH manual coal feed type coal fried boiler
8.Application: medicine, chemical, light industry, textile, building material, cultivation, food and beverage, plastic foam, printing, dyeing and washing, rubber processing, paper products,wood processing, hotel, clothing and leather manufacturer etc.
Structure
The fuel enters the furnace and burns on the grate. The flue gas from the production enters the convection tube bundle on both wings along the bottom of the boiler barrel through the smoke outlet on the middle partition wall, enters the threaded smoke pipe through the front smoke box, passes through the dust collector, and is pumped and discharged into the atmosphere through the chimney by the induced draft fan.
Technical characteristics
1. High Quality Control: In manufacturing processes, we has adopting steel strength test, automatic steel cutting/ plate rolling/ welding, 100% x-ray welding check, magnetic particle check c-scan ultrasonography check, fluorescent penetrating check, hydraulic (water) pressure test, boiler thermal efficiency test,etc, to make sure all finished products is qualified.
2. Simple Structure: DZH boiler adopting threaded fire tubes, single water drum, horizontal shell type boiler with 3 fire-passes structure, water-tube fire-tube mix design. Most important, the combustion fixed chain grate can also suit any kind of biomass. The small flakes chain grate can reduce fuel leakage, and also let the broken chain grate flakes is convenience of replace.
3. Better Adaptability on Fuels: Comparing with DZL boiler, DZH boiler has better adaptability on fuels, it can fire coal, rice husk, nut shell, sawdust, waste wood pieces, also can fire wood logs, straws. But, DZH boiler can only support manual fuel feeding, and manual ash remove.
4. Safe Operation: DZH series is equipped with automatic water-level control, automatic pressure control, automatic interlock chain stop protection, free settable working.

Remarks: The fuel consumption in above table are counted the low calorific value of biomass pellet as 17084 KJ/Kg (4085Kcal/Kg), if the low calorific value of actual biomass fuels is bigger than this, the corresponding fuel consumption will more save than above data in table.
Automatic control and fault protection features
Boiler steam pressure automatic regulation system: boiler steam pressure automatic regulation system control system into the state of work, to meet the necessary conditions of combustion: boiler steam pressure is higher than or equal to the set pressure limit, the control system output stop signal.Until the induced draft fan is stopped.
Water supply automatic control: when the system is working or normal, start the water pump, the water pump will work, the water level differential pressure transmitter will detect the water level signal and keep the water level of the drum stable.Ensure the quality of steam.The water level gauge shows the boiler water level.
Manual control: you can also manually control the water pump by touching the button manually on the control panel.
