The DZL biomass boiler is a single drum longitudinal chain grate boiler that uses biomass pellets as fuel, and is a new generation of high-efficiency and energy-saving boiler products. The fuel biomass it uses is an ideal renewable energy source, with a large output every year. Using it instead of coal combustion can not only reduce costs for enterprises and bring rich economic returns, but also increase farmers' income through waste utilization, achieving the common development of economic and social benefits. Not only that, this boiler also has advantages such as fast pressure rise, high thermal efficiency, and large heating area. 

The DZL biomass boiler is a horizontal three return water fire tube boiler designed with high-efficiency and energy-saving enhanced combustion technology to ensure full combustion of fuel. Even better, the volume of the furnace and combustion chamber is very large, which is conducive to the combustion and settling of fly ash. The dust coarse separation turning chamber is installed at the outlet flue gas window, which achieves the purpose of dust removal in the boiler furnace, reduces the emission of flue gas, and meets the national environmental protection regulations.

Performance characteristics: Using threaded smoke pipes for heat transfer improves thermal efficiency and reduces energy consumption. The application of membrane water-cooled wall structure has improved the heat transfer coefficient and efficiency, and reduced heat loss. The threaded smoke pipe is installed inside the pot shell, with less overall air leakage and less heat loss from smoke exhaust. The welding seams of the boiler are all made using advanced submerged arc automatic welding technology to ensure welding quality. The tail flue is equipped with a dust collector to ensure that smoke and dust emissions meet environmental requirements. High level of automation, with functions such as automatic water regulation, low water level interlock protection, and high and low water level alarm. The advanced arched design creates a clear inverted "alpha" flame, which is conducive to the combustion of inferior coal and has strong adaptability to coal types. The control and monitoring instruments are complete, and the boiler operation is safe and reliable. The setting of the two wing flue allows the flue gas to smoothly enter the front smoke box, ensuring that the temperature of the previous tube plate is the same and avoiding the occurrence of tube plate cracks due to temperature stress. The grate adopts a new type of small scale grate plate, which adds a unique safety ring, making the grate operate stably and reliably, and improving combustion efficiency.

DZL-T biomass boiler is a new type of high-efficiency, low-carbon and environmentally friendly boiler that uses biomass particles as fuel. It is mainly divided into biomass steam, biomass thermal oil furnace, and hot water boiler. Biomass pellet fuel is a process that utilizes all discarded crops such as straw, rice straw, fuel wood, sawdust, peanut shells, melon seed shells, corn cobs, sugar beet pulp, bark, etc., through crushing mixing extrusion drying, and finally produces pellet fuel. Its raw materials are widely distributed and its processing technology is advanced. Biomass pellets are known as green coal and are a clean energy source. As a fuel for boilers, it has a long combustion time, high furnace temperature for enhanced combustion, is economical, and has no pollution to the environment. Belonging to renewable energy, the burned ash residue is a very good fertilizer that can be recycled. It can replace traditional boilers to burn non renewable resources such as wood, coal, and natural gas, and is an efficient and energy-saving environmentally friendly product.
