Overview

The chain grate biomass boiler is a fully automatic, high-efficiency, and eco-friendly industrial boiler optimized for renewable biomass fuel combustion. Adopting a mature horizontal chain grate structure and three-pass heat exchange design, this boiler realizes continuous fuel feeding, stable combustion, and automatic slag removal. It solves the problems of low efficiency, unstable operation, and high pollution of traditional biomass boilers. As a clean energy heating equipment compliant with international environmental standards, it is widely applied in industrial steam supply, commercial central heating, and factory hot water supply scenarios, helping enterprises reduce energy costs and achieve green production transformation.
Core Features & Technical Advantages
Ultra-wide Fuel Adaptability & Low Operation Cost
Different from fixed grate boilers with strict fuel requirements, our chain grate biomass boiler supports diverse biomass fuels, including biomass pellets, wood chips, rice husks, palm shells, straw, corn cobs, and other agricultural and forestry waste fuels. It also allows mixed combustion of biomass and a small amount of clean coal, with no strict restrictions on fuel particle size and humidity. Biomass fuel is renewable, low-cost, and easily accessible globally, effectively cutting enterprises' long-term energy consumption expenses compared with gas, electric, and coal-fired boilers.
High Thermal Efficiency & Stable Combustion Performance
Equipped with a scientific front and rear arch air distribution system and multi-stage air supply device, the boiler forms a uniform oxygen supply environment in the furnace, realizing sufficient semi-combustion and thorough combustion of biomass fuel. The optimized three-pass flue gas heat exchange structure and threaded smoke tube heat transfer technology maximize heat absorption, reducing exhaust gas temperature and heat loss. The overall thermal efficiency reaches above 85%, ensuring stable and continuous steam/hot water output with fast pressure rise, reaching rated working pressure within 20 minutes for efficient production support.
Full Automatic Operation & Labor Saving
Configured with an intelligent PLC automatic control system, the boiler integrates automatic feeding, variable-frequency air volume adjustment, automatic grate speed regulation, and automatic slag removal functions. The whole operation process requires minimal manual intervention, greatly reducing labor intensity and operational errors. The system supports real-time monitoring of pressure, temperature, water level and other core data, realizing unattended automatic operation and effectively saving labor management costs for enterprises.
Safe & Eco-friendly, Global Compliance
Built with multiple safety protection mechanisms including overpressure protection, water shortage protection, over-temperature protection and flameout protection, the boiler avoids operational risks and ensures long-term safe and stable operation. With complete fuel combustion and low smoke and dust emission, it effectively reduces sulfur and nitrogen oxide emissions. All emission indexes comply with EU environmental standards and international industrial energy-saving regulations, helping enterprises pass environmental audits and meet green factory certification requirements.
