SZL Biomass (Coal-fired) Boiler
The SZL-type biomass-fired boiler adopts a double-drum longitudinal arrangement with a chain grate combustion method. Its fuel is biomass, a clean energy source. During combustion, it produces no waste gas, waste residue or smoke. Meanwhile, biomass features low cost, easy accessibility and realizes waste recycling.
This boiler consists of two main components: the upper heating surface of the boiler body and the lower combustion equipment. The two sides of the furnace adopt a membrane water wall structure, which improves airtightness and increases heating surface area.

Heating Sector
Suitable for residential communities, schools, and hospitals providing a comfortable indoor environment.

Industrial Production
Steam or hot water for chemical, food, textiles, and pharmaceutical industries.

Agricultural Applications
Regulates indoor temperature in greenhouses and heats animal sheds for husbandry.

Power Generation
Core equipment for biomass power generation projects driving turbines to generate electricity.
