Introduction

Biomass/wood pellets fired boiler:
1. why use biomass/wood pellets as fuel burning ?
The biomass/wood pellet fuel has a large calorific value,  it has high purity and contains no other impurities that do not generate heat. There is little ash after combustion, emit less harmful gas, environmental-friendly. 
2. Best Choice---SZL D type model for biomass/wood pellets fired boiler !
Yuanda SZL D series won the national science and technology progress award, is key-promoting products and energy-saving projects in China. Core technology: Whirlwind burning chamber structure, Indenpend wind chamber sturcture, Large furnace capacity, ensure fuel burning entirely, Membrane water wall construction, Front-rear water-cooled arch design.
 

Technical advantages:

1. Unique structural design

According to different capacity, different numbers of independent air bins are arranged from front to back of the grate.

The user can reasonably adjust the air distribution according to combustion conditions to ensure fuel burning fully.

Secondary air is input to disturb fuel gas in the furnace, to ensure the fuel is burnt totally. 

Feeds evenly feeding and avoid flashback.

2. Low NOx emissions

Graded air supply and special furnace arch structure decrease the NOx emissions to 100mg/m³.

Different biomass raw materials are analyzed by numerical simulations, thermal efficiency is more than 90%.
