Products Description
As a critical core component in biomass boiler combustion systems, the Biomass Boiler Grate Bar undertakes the key tasks of supporting biomass fuel, guiding air circulation, promoting full combustion, and discharging ash residues. Its performance directly determines the combustion efficiency, operation stability, service life of the biomass boiler, and even the energy conservation and environmental protection effects of the entire heating or power generation system. Designed specifically for the characteristics of biomass fuels (such as wood chips, straw, rice husks, and other irregular, high-moisture fuels), the Biomass Boiler Grate Bar solves the pain points of ordinary grate bars such as poor high-temperature resistance, easy wear, and slag bonding, becoming an indispensable key part in the efficient operation of biomass boilers.
Made of high-quality heat-resistant alloy steel (e.g., Cr25Ni20, Cr18Ni9) and special wear-resistant cast iron, tailored to the high-temperature, wear and corrosion conditions of biomass boilers.Achieves excellent mechanical properties through precision casting and heat treatment.

Product advantages
High-Quality & Scenario-Adapted Materials：
Selected high-grade heat-resistant alloy steel (Cr25Ni20, Cr18Ni9) and special wear-resistant cast iron, perfectly adapted to the high-temperature, wear and corrosion working conditions of biomass boilers.
Precision Crafting for Superior Performance：
Formed by precision casting and professional heat treatment, boasting excellent mechanical properties with hardness ≥50HRC and tensile strength ≥800MPa.
Outstanding High-Temperature Resistance：
Stable operation in a wide temperature range of 600℃-1200℃, with strong adaptability to the high-temperature environment of biomass combustion.
Ultra-Long Service Life：
Service life reaches 8000-12000 working hours under normal working conditions, reducing downtime for replacement and lowering operation and maintenance costs significantly.
Craftsmanship & Functional Features
Adopting lost foam precision casting technology, the biomass boiler grate bar has a dense internal structure, no sand holes or cracks, and high dimensional accuracy, ensuring a perfect fit with boiler equipment. The surface is treated with high-temperature nitriding, which further enhances wear resistance and oxidation resistance, effectively resisting erosion by high-temperature flue gas and abrasive ash.
In terms of functionality, it features reasonable ventilation slot design, which ensures sufficient air circulation to promote full combustion of biomass fuel (such as straw, wood chips, and biomass pellets), reducing energy waste. At the same time, the grate bar has good thermal conductivity, avoiding local overheating deformation and improving the overall operation stability of the boiler.
