Product Description

Biomass Boiler Banner

The DZH-type traveling grate biomass-fired boiler is a single-drum longitudinal boiler developed in response to environmental protection policies. It utilizes biomass pellets processed from agricultural wastes such as straw, sawdust, and peanut shells. The sulfide emission in flue gas is significantly lower than that of coal-fired boilers, complying with strict environmental standards.

This boiler features a horizontal four-pass fire-tube and water-tube design. With a new furnace arch design, it maximizes fuel combustion efficiency, reaching thermal efficiency up to 83%.

Frequently Asked Questions

What fuels are compatible with the DZH series?
The DZH series is highly versatile and can burn biomass pellets, wood chips, straw, peanut shells, and coal. It supports single-fuel or mixed combustion.
What are the environmental advantages of biomass boilers?
Biomass is considered carbon-neutral. Flue gas emissions contain significantly lower sulfur and nitrogen oxides compared to traditional coal boilers, meeting modern environmental regulations.
Does the boiler come with safety certifications?
Yes, our boilers are manufactured under Grade A standards and comply with international certifications such as ISO9001 and CE, ensuring high safety and reliability.
How is the boiler protected against overpressure or dry burning?
The system is equipped with automatic water level controls, pressure regulation valves, overpressure alarms, and explosion-proof doors for multi-layered safety protection.
What kind of maintenance is required?
Regular checks of water level and pressure parameters, cleaning of internal scale and flue pipe ash, and periodic inspection of valves and instruments are recommended to ensure peak performance.
Can you support international shipping and export documents?
We provide full export support, including CE/ASME documentation, logistics booking, and customs declaration, following trade terms like FOB or CIF.
