DZH series manual coal fired steam boiler, use movable fire grate, equip with blower, draft fan, economizer, deduster, automatic water treatment, water pump, steam header, control cabinet, valves and meters etc auxiliary machines. Due to the less of auxiliaries of this series boiler, so low fault of machines, reduce maintenance cost, easy operation, save time and materials, is an economical boiler type. Suitable for various types of coal fuels, environmental protection, price position moderate, is the first choice of small and medium enterprises who use steam for processing line.
Biomass Steam Boiler is a  necessary equipment for a plywood factory, to provide heat for the veneer dryer, hot press and laminating hot press etc.
According to the total heat demand to choose a proper model.Two heat-conducting mediums ,steam and thermal oil.

Steam Boiler specification sheet

(1) The arched tube sheet and the threaded smoke tube are used to form the drum, so that the drum is changed from a quasi-steel body to a quasi-elastomeric structure, and the bracing parts in the tube plate area are eliminated, and the stress is reduced. The smoke pipe in the tube sheet is changed from two passes to a single pass, which solves the problem of tube sheet cracks.
(2) As the lower part of the drum is arranged with the rising pipe row, the dead water area at the bottom of the drum is eliminated, so that the sludge is not easy to deposit, and the high temperature area of the drum can be well cooled, preventing the bulge in the lower part of the drum.
(3) The effective heat transfer threaded smoke tube is adopted to obtain an enhanced heat transfer effect, achieve the characteristics of rapid heating and pressure rise of the boiler, and improve the thermal efficiency of the steam boiler.
(4) The structure is compact, and compared with the same type of boiler, the overall size is small, which saves the investment of the boiler house infrastructure.
(5) Stable operation, convenient adjustment and sufficient output.
The fuel can be biomass pellet, wood chips, waste wood, sawdust, corn stalk, rick husk, biomass pelelt
Application for biomass steam boiler 
Wood fired steam boiler has high heating temperature, low working pressure, energy saving, and can be widely used in various industrial heating processes. Such as petrochemical industry, synthetic fiber industry, textile printing and dyeing, plastic rubber, paper industry, wood industry, building materials, machinery industry, food industry, electrical equipment, coking industry, metal and foundry industry, detergent industry, fat and coating industry, carbon industry.

1. What are the differences between vertical type boiler and horizontal type boiler with the same capacity?

1. Structure of vertical boiler is compact, occupy a limited area,

2. Convenient on installation and removal.

3. Low cost and investment on capital construction. Steam exhausted fast and sufficient.

1. The combustion space of horizontal is big, fuel can be burned completed.

2. The thermal efficiency is higher than the vertical boiler,

3. Horizontal type: less thermal loss, stronger output, and higher steam quality.

2. What are the limitation (size, humidity, chemical element concentrations) of coal fuel/solid fuel/wood fuel?

Size requirement of coal:6-25mm

Size requirement of blending coal: <50mm (the coal less than 6mm should less than 30%)

Diameter of biomass particle: 6~10mm, length: 25~50mm, water content < 15%, ash content < 2%, sulphur content<0.07%, chlorinity <0.07%, nitrogen content < 0.5%

3. What is the size of furnace door and blower hopper?

Size of furnace door:

Standard elliptical furnace door:300*800*1500

Blower hopper size:

2 tons conical hopper: 1400*800*1500

4 tons conical hopper: 2200*1400*1500

4. What is the combustion mode of coal/biomass fired boiler?

The combustion mode of coal/biomass fired boiler is layer combustion. Place the flue on the fixed or moved grate, to form an evenly fuel bed with a certain thickness, air comes from the bottom of grate, and combustion occurred on the fuel bed.
