DZL series coal fired steam boilers are designed as single-drum boilers with fire tubes and water tubes. They have fast heat conduction, fast steam pressure rise, strong adaptability to biomass fuel, compact structure and high thermal efficiency. This series of steam boilers adopt the latest science and technology in the industry such as arched tube plate and threaded flue smoke pipes, which effectively improves the overall efficiency of the boiler and prevents the occurrence of faults such as grate coking and tube plate leakage.

Performance advantage

DZL series coal fired steam boiler is the single drum longitudinal type water and fire tube shell water boiler, the burning equipment is the chain grate.

1. The fire grate is compact and dense. It is especially suitable for the combustion of biomass particles.

2. Boiler internal heating area is larger than the same specifications of coal-fired boilers, to make up for the disadvantage of biomass fuel combustion value.

3. The condition is stable, continuous fuel combustion. By adjusting the secondary speed air volume, control the speed of combustion ignition.

4. The biomass steam boiler is easy to operate, user-friendly design, without complicated procedures.

5.It takes the thread smoke tube to enhance heat transfer, improve the heat transfer coefficient and thermal efficiency.

Due to disturbance of smoke in the tube, the smoke pipe is not easy to accumulate dust ,it can clean by itself .

6.Fuel easily obtained, the ash can be recycled.

-automatic fuel feeding duel to chain grate design;

-high efficiency due to big heating surface and grate area;

-low emission,friendly to environment;

-wide fuel adaptability, applicable for wood pellet, coal, palm nuts, etc;

-intelligent boiler controller with PLC and touch screen, easy for operation and parameters setting;

-good looking & long life span;

This coal steam boiler is widely used in schools, textile mills, clothing factories, printing and dyeing factories, restaurants, food factories, beverage factories, bean products factory, meat products factory, cannery, winery, pharmaceutical factory, packaging factory, building materials factory, coating factory, swimming pool and other enterprises and institutions.
