DZH biomass fired steam boiler is single drum boiler with both water tubes and fire tubes, the combustion equipment is moving grate, the fuel could be fed manually or mechanically. To avoid coking, increase the combustion space and adopts secondary air design. Biomass fuel is clean and renewable fuel. Compare with oil/gas fuel and coal fuel, it has the advantages of environmental protection, energy saving, and low cost. Except bagasse and rice husk, the boiler could also burn wood chips, sawdust, peanut shell, cotton hull, stick, and other biomass fuels.

This DZH bagasse & rice husk boiler uses the new scientific achievement, such as arch tube plate, and spirally corrugated tubes to solve the problem of low thermal efficiency, coking, tube plate cracking, drum bulging, insufficient output, and environmental pollution. Jinzhen Boiler has a mature R&D and design team, could customize the boilers based on customers' 
requirement. 

1. High thermal efficiency

1) The spirally corrugated tube strengthen the heat transfer, improve thermal efficiency. The flue gas has the foundation of disturbance, avoid ash depositing in tube.

2)The furnace wall was poured entirely by the heat-resistance concrete and high-temperature-resistance refractory brick, and the boiler shell uses aluminium silicate board for heat preservation, low heat loss.

3) Equipped with economizer, make full use of the heat of flue gas, decrease the exhaust smoke temperature, increase thermal efficiency.

2. Anti-coking

1) For the easy coking biomass fuels, increase the size of furnace, large space to achieve sufficient combustion.

2) Adopts unique double secondary air design, improves the ignition condition of biomass fuel, sufficient air supply to make sure the high combustion efficiency.

3. Avoid bulging

The riser tube bundle under the drum, remove the dead water region at the bottom of drum, sludge is not easy for depositing, the high temperature area of drum has better cooling, prevent bulging.

4. Avoid tube plate cracking

1) The wood fired steamboiler adopts arched tube plate and spirally corrugated tube, change the quasi-steel body into quasi-elastic body structure, reduce stress.

2) Arrange two sides gas duct in drum, the smoke gas could enter into the front smoke chamber smoothly, the temperature of tube plate is lower than 600ºC, avoid cracking leaded by high temperature.

5. Sufficient output

Industrial steam boiler adopts horizontal type three pass structure and large furnace, to ensure the sufficient combustion, and the boiler could absorb the thermal expansion effectively. The large diameter boiler drum increases the radiant heating surface, to ensure the sufficient output.

6. Environmental protection

1) The biomass fuel do not content sulfur, do not pollute the environment, and the cost on biomass fuel is low.

2) The splayed wall and smoke outlet have the function of dust removal, decrease the concentration of smoke emission.

Q1: How can you get the best price quickly?
(1) We need to know the boiler capacity, the fuel you plan to use and the steam pressure you need, and then we can confirm the boiler model. 
(2) Customer needs to provide us your name, email address and company name, and then we will send you price list immediately.And if you use whatsapp, skype or wechat, you can provide us your ID, it will be more convenient for our communication.

Q2: Why should you believe our boiler quality?
(1).Strength calculation report with applied materials information;
(2).100%NDT(non-destructive inspection) report of steel plate, tube and welding rod;
(3).100% X-ray inspection(welding seam): ensure the quality of entire boiler;
(4).Hydrostatic test: ensure the standard working pressure and safety;
(5).Third-party inspection report:By Henan Boiler Inspection Institute;
(6).Passed ISO:9001 and SGS certificate.

Q3: What about the installation and Commissioning?
After you receive the boiler, we will guide you to make some preparation for installation;If necessary, our expert will fly to your local place in 72 hours. The experts will responsible for guiding installation and commissioning. 
But the buyer will be in charge of :
(1) The round air-tickets costs from Zhengzhou city to your project site.
(2) Board and lodging of seller's workers for entire period at the end user's site.
(3) Service fee for guiding engineer:100$/day/person.
Q4:What is the using life of your boiler?
A:Normally the boiler is designed for 20 years life span, but with right operation and good maintenance,the boiler can be used for 20-25 years.
