Boiler sturcture features

1. Wing flue
Function:cut down the smoke temperature inside the high temperature tube plate ,so as to slow down subcooled boiling
Purpose:reduce the thermal load at the bottom of boiler,prevent tube plate cracking ,prevent convex drum
2. 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
3. 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
4. Smoke and dust separator chamber
F: Separate smoke and dust according to inertia
P: reduce the original effluent concentration of soot
5. Optimized design CAD
F: Choose the best furnace from dozens of options
P: improve economical efficiency
6. Convex tube plate
F: improve tube plate flexibility,so as to reduce the heating stress of welded sew at the pipe end
P: prevent tube plate cracking, cancel bracing,simplify the structure
7. 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
