Double drum chain grate coal fired boiler

Double Drum Chain-grate Coal-fired Steam Boiler
Double Drum Chain-grate Coal-fired Steam Boiler, which is SZL Series steam boiler, as name implies, is of double drums, chain-grate horizontal steam boiler.
Double drum chain grate boiler series can also be chain grate biomass boiler and the boiler is commonly used as a boiler construction, in the boiler furnace is provided with two drum and two drum axis parallel to each other, and the two drum pipes communicating through a number of furnace, thereby heat exchange
Characteristics of Double Drum Chain-grate Coal-fired Steam Boiler
1.Double drum and horizontal layout, up and down assembly structure, save space.
2.Reliable and safe operation.
3.Compact structure, reasonable water circulation, fast start-up.
4.Newly furnace arch structure and insulation materials make less radiating loss, improve thermal efficiency. 5.Use advanced domestic chain grate, reliable process, save energy, reduce installation and maintain workload. Reasonable air distribution, double side air inlet for combustion system which improves the efficiency. With layered coal feeder, burning efficiency is improved, carbon is reduced, save coal about 10%.
6.Automatic control system, high mechanization degree, easy operation, secure running.
7.High dust-collecting efficiency, built-in ash removal, environmental.
8.Fast packaged for shipment, good shape.
Generally, industrial steam drum boiler can also be single drum and double drum boiler and they are usually called DZL and SZL chain grate boiler. The chain grate boiler is often used as coal fired boiler and biomass fuel fired boiler for the world industry.
