 Advantages  DZL chain grate coal boiler 

1. Smoke and dust separator chamber

Separate smoke and dust according to inertia,reduce the original effluent concentration of soot.

2. Optimized design CAD

Choose the best furnace from dozens of options,improve economical efficiency.

3. Convex tube plate

1) Improve tube plate flexibility, so as to reduce the heating stress of welded sew at the pipe end.

2) Prevent tube plate cracking, cancel bracing,simplify the structure.

4. Large size of simple circulation loop drop pipe and lower set box

Increase the flow rate of water on water cooling wall in order to prevent subcooled boiling. To prevent pipe explosion,Increase the reliability of water cycle

5. New pattern of furnace arch

Strengthen the combustion, could burn kinds of fuel: wood, coal and biomass, improve combustion efficiency.
