1.Design the cyclone chamber inside the chamber of the stove
When the high temperature smoke through the cyclone chamber,smoke rotate with high speed and burn thoroughly.Improve the heat efficiency of boiler,the big dust settle down ,achieve the result of secondary combustion and first dust removal.
Energy conservation,high efficiency,environment friendly
This design obtains national patient
2.Separate wind chamber structure
Make air regulation sensitive and make wind uniformly in landscape orientation in the reliable longitudinal wind chamber.
Resolve the wind plug,wind channeled,partial burn phenomenon,
The design obtains national patent.
