DZL type coal fired steam boiler is a horizontal three return fire tube and water tube type boiler. There are two fire tubes in the boiler barrel , with both sides light pipe water-wall tubes; DZL coal fired boiler is widely used in textile industry, chemical industry, hospital, school.
Working Process of DZL Coal Fired Boilers
- Fuel from coal scuttle fell to grate stoker, Chain grate feed coal from stoker to burning chamber.
- High temperature smoke through four pass fire tube and water tube, which make sure the heat is absorbed by boiler water.
- Finally through the induced draft fan smoke the introduction into the flue, dust catcher and the chimney, the last row to the atmosphere.
