Product Specification

1-4 ton capacity DZH biomass and wood pellets fired steam boiler for sale with low biomass fuel cost

Brief Description
The DZH biomass boiler produced by the company is a horizontal three-return tubular boiler. The combustion process of the fuel can be briefly described as: the operator can throw the biomass fuel into the furnace, and after the fuel is fully burned in the furnace, the high-temperature smoke enters the front smoke box through two sets of airfoil flues arranged on both sides of the furnace. The threaded tube inserted into the drum is then inserted into the rear smoke box. It is then drawn into the flue, dust collector and chimney by an induced draft fan and finally discharged to the atmosphere. The boiler is safe and stable in operation, easy to operate, and low in failure rate.

Product advantages
The DZH biomass steam boiler produced by the company has the advantages of maturity, advancement, stability, reliability and economy.
1. Maturity: Our company is one of the earliest manufacturers of material-producing threaded tube boilers in China. Over the past 30 years, the products have been updated many times and become more mature. Thousands of similar products have been produced.
2. Advanced: It adopts a number of advanced technologies, such as threaded tubes, in-furnace intensified combustion, etc. The control system can adjust independently for the following situations, such as automatic adjustment of steam pressure, self-controlled water supply, high steam pressure protection, and inside the pot. Water shortage protection, abnormal water level alarm, low water level interlock protection, motor overload protection and automatic power failure protection.
3. Stability: The boiler runs smoothly, the failure rate is low, and no major safety accidents occur; the longest running time of the early boiler has reached more than 20 years.
4. Reliability: The only boiler manufacturer in China that has conducted 200,000 fatigue tests on shell boilers.
5. Economical: high thermal efficiency, fuel saving and good economy.
