The SZL type biomass boiler utilizes a double-drum longitudinal arrangement and operates with a chain grate combustion method. It runs on clean energy biomass fuel, which not only produces no waste gases, waste, or smoke during combustion but also is cost-effective and easily accessible, achieving waste recycling. This aligns with market trends and customer needs. The boiler consists of two major components: the upper body heating surface and the lower combustion equipment. Fuel burns within the combustion equipment, and the resulting flue gas passes through the furnace, ash chamber, and convection tubes before entering the tail flue. It is then discharged into the atmosphere via a dust collector, induced draft fan, and chimney.

The SZL type biomass boiler features a membrane-type water-cooled wall structure on both sides of the furnace, which not only improves the boiler's sealing but also increases the furnace volume and heating surface area. The arrangement of secondary air (controlled by valves) on the front and rear walls ensures complete combustion of the fuel, enhancing combustion and thermal efficiency while reducing fuel costs. It also minimizes waste and slag production. Additionally, it boasts high automation levels, stable operation, and comprehensive maintenance functions, making it an ideal choice for many businesses when purchasing boilers.

Performance Advantages

The heat exchange surface arranged in a crossflow configuration offers high heat exchange efficiency, and the boiler operates with stable efficiency.

Chain grate panel, both front and rear smoke box panels are cut using CNC plasma cutting machines, ensuring neat and aesthetically pleasing finishes.

Large pot capacity, fully equipped interior.

Boilers feature automatic water level regulation, high/low water level automatic alarms, overpressure automatic protection, and automatic shutdown protection in case of flameout.

Boilers operate smoothly and have certain overload capabilities.

Front and rear arches match well, with a large coverage of the furnace arch and high furnace temperature.

Dual pot assembly, high combustion efficiency, saving operation costs by 5-10%.

The cross-sectional ratios of the heating surfaces' descending areas to the rising pipes are reasonable, and the combustion conditions are stable.

The air volume required for different fuel types and combustion stages in each wind chamber can be manually adjusted. The lateral air pressure is consistent, preventing any partial combustion phenomena.
