Low Running Cost Coal Fired Steam Boiler Automatic Chain Grate
Boiler
Product description
1. DZL series steam boiler is a horizontal type single drum
packaged boiler, the combustion equipment is chain grate. Both
sides water tube wall of furnace are radiation heating surface, the
two wing flue are convection heating surface, corrugated tubes are
arranged in drum, strength the disturbance of flue gas, improve
heat transfer efficiency.
2. The furnace wall is use heat resistance concrete, high
temperature resistance refractory brick, and aluminium silicate
board for heat preservation, decrease heat loss, increase thermal
efficiency. The boiler adopts upper drum, water tube wall and
heater are bilateral symmetry. The drum is consisted of barrel and
the front and rear tube plate.
3. This series boiler has the characteristics of high thermal
efficiency, sufficient output, adopt different coal and biomass
fuels, and environmental protection.
