SZL Water Tube Biomass Fired Boiler

SZL Series Water Tube Biomass Fired Boiler

SZL series biomass steam boiler is a double-drum, horizontal water tube boiler with chain grate combustion. It adopts modular assembly—small capacity models are quick-assembly type, while larger ones are split into upper heating and lower combustion sections. The boiler features water walls, steam-water separator, blowdown device, and an economizer for improved efficiency. It is suitable for burning various biomass fuels like wood chips, rice husk, bagasse, and coconut shell, making it ideal for industries such as textiles, food, and chemicals.Compared with coal-fired boilers, biomass fuels have lower cost and lower operating cost.

Water Tube Biomass Fired Boiler

Product Advantages

Easy to Install

Boiler is composed of upper body and chain grate 2 big parts, which only need to gather up and bricking the lower furnace, easy installation, lower cost and short time.

Both Sides Air Inlets

The boiler adopts double-side air inlet & independent air chamber structure, which can flexibly adjust the air volume and wind pressure of each air chamber to ensure the combustion performance.

Remote Monitoring

Advanced control system--remote monitoring, if there is any abnormality during the operation of the boiler, providing the first time guidance to reduce the failure rate and loss.

Support a Variety of Biomass

Larger and higher furnace ensure the fully combustion, many kinds of biomass can be used on this boiler, strong applicability
