Biomass Pellet Wood Fired Coal Hot Water Boiler With Chain Grate
DZL Biomass hot water boiler can burn both coal and biomass fuel
with a high efficiency. Compact structure and easy installation
ensure efficient, clean, economic, safe and stable boiler
operation, so it is widely used as an energy-saving and
environment-friendly equipment in industry.Biomass Hot water
boilers are the perfect sustainable solution for space and process
heating in a wide range of industrial and commercial applications
including process steam.
Features of coal fired hot water boiler
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
