SZL series biomass steam boiler

ZG boiler SZL series biomass boiler adopts double pot vertical arrangement. The water wall of the wall on both sides of the furnace adopts membrane water wall structure. The boiler is clean and has high thermal efficiency.
  • Rated steam capacity: 6-30 T/H
  • Rated steam pressure: 1.25 to 2.5 MPa
  • Rated steam temperature: 194 ~ 226 °C
  • Applicable fuel: Biomass Fuel, Rice Husk, Bagasses

Products introduction:

ZG boiler SZL series biomass boiler large chain grate boiler combustion system water-cooled arch technology and membrane water wall technology are skillfully applied to the assembled boiler, which increases the heat transfer area of ​​the boiler, reduces heat loss and improves boiler thermal efficiency. The chain grate biomass boiler combustion equipment adopts a chain-series chain grate, which is driven by a continuously variable transmission device, and the boiler is simple to operate.

SZL series biomass steam boiler performance advantages:

1. Good fuel adaptability

The boiler adopts a chain-series chain grate combustion equipment, which adopts a suspension-layered combustion mode, which can adapt to various biomass fuels and has sufficient combustion.

2. High steam quality

The upper drum is equipped with a steam-water separation and continuous sewage device; the lower drum is equipped with a regular sewage discharge device, and a row of sewage discharge devices are arranged in series to ensure steam quality.

3. Simple operation

The chain grate biomass boiler does not need to add bed material, and does not need to consider the bed material addition system. During the operation of the boiler, the chain grate performs low-speed translation movement, the boiler has high degree of automation and simple operation.

4. Advanced technology

The boiler adopts a membrane water wall structure with good heat transfer effect. In the boiler furnace arch, innovation has been made to form the front and rear arch structure, which increases the radiation heating surface of the furnace and has a stronger overload capacity. The length of the grate is increased, and six independent plenums are arranged along the longitudinal direction of the grate to improve the thermal efficiency of the boiler.
