DZL Horizontal Coal Steam Boilers

1.The boiler adopts the latest research results,such as:arched tube plate,screw thread smoke tube,hot water boiler backwater ejection technology,solves the pot type boiler tube plate crack at the lower part of the drum,drum kits,water wall tube broken ,low thermal efficiency,low output,poor adaptability of coal. 2.Combustion:fuel from coal scuttle fall in front of the stove grate,during operation ,after coal preheating and dry distillation,ignition,combustion,the slag drop into the slag bucket,then been removed out furnace by by slagging machine at any time.Furnace arch uses herringbone arch,improving the conditions of ignition.Flue gas forms vortex between the throat of the front,rear arch mixed with air.After combustion ,flue gas enters the two wings flue,through the front smoke box into the thread smoke tube,then go through cast iron economizer(hot water boiler no need )dust collextor,finally discharged by lead fan to chimney. url:http://www.slboilers.com
