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.

1. Return water eject to the high temperature tube plate
F: Improve the flow rate of high temperature tube plate and prevent
subcooled boiling
P:prevent the tube plate cracking
2. Ejector pipe
F:Increase the flow rate of water on water cooling wall in order to
prevent subcooled boiling
P:To prevent pipe explosion,Increase the reliability of water cycle
3. Smoke and dust separator chamber
F:Separate smoke and dust according to inertia
P:reduce the original effluent concentration of soot
4. Optimized design CAD
F:Choose the best furnace from dozens of options
P:improve economical efficiency
5. Convex tube plate
Function:improve tube plate flexibility,so as to reduce the heating
stress of welded sew at the pipe end
Purpose:prevent tube plate cracking, cancel bracing,simplify the
structure
6. Large size of simple circulation loop drop pipe and lower set
box
F:Increase the flow rate of water on water cooling wall in order to
prevent subcooled boiling
P:To prevent pipe explosion,Increase the reliability of water cycle
