DZL Series Chain Grate Biomass Steam Boiler

The DZL type quick assembly biomass steam boiler is a single-drum, longitudinal chain grate boiler, designed for high-efficiency and eco-friendly steam generation. It is suitable for a wide range of biomass fuels such as wood chips, rice husks, bagasse, peanut shells, cotton shells, and coconut shells — as well as molded biomass and even coal.

This boiler features a hybrid water-tube and fire-tube structure, with water wall tubes on both sides of the furnace for radiant heating, and screw fire tubes in the drum for convection heating. Its symmetrical design, combined with a rear economizer, maximizes thermal efficiency while minimizing energy loss.

Equipped with mechanical ventilation (induced draft fan) and a spiral slag discharger, the DZL boiler offers automated operation, complete with comprehensive control and monitoring instruments for safe and reliable performance. The discharged ash and slag can be repurposed as organic farm fertilizer, contributing to sustainable resource use.

To meet stringent environmental standards, the boiler can be fitted with a bag dust collector, dual-tower desulfurization system, and other emission control technologies. Biomass fuel, as a renewable green energy, not only reduces operating costs compared to coal, but also aligns with global trends in low-carbon, sustainable development.
