Product Description

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.

3.Boiler water circulation  progresses on natural circulation and ejection. The radiation heating surface is  left and right side cold water  wall  .The two wings of boiler furnace are main  convection heating surface.The thread smoke tube in boiler furnace are  convection heating surface.The boiler furance is seperated by  fold smoke wall-firebox and reburning chamber .Boiler main body is covered by  three-dimensional shape plate shell .
