SZL shop-assembled water tube steam boiler is the horizontal type double drum longitudinal type chain grate water tube steam boiler. The boiler is assembled with two drums and convection bank inside. Water wall tubes are placed on the left and right side of the burner. Moreover, there is a steam-water separator and surface blow down device that fixed in the upper drum, and a periodic blow down device fixed in the another drum. Economizer is distributed on the tail of the boiler.
Application:
1.Petroleum and chemical industry, polymerization, melting, condensation, distillation, forced heat preservation.
2.Textile printing and dyeing industry: hot finalize design, thermosol dyeing, baking, calender drying and hot air stenter.
3.Plastic and rubber industry: hot-press, hot-extent, extrusion, calendering, injection, conveyor dryer, etc.
4.Paper industry dry, corrugated paper processing, glue roller, etc.
5.Machinery industry: spray drying of printing, assembly processing, dry cleaning.
6.Food industry: baking bread and baking cookies, cooking pot, autoclave and conveyor dryer.
Performance Advantages:
1.The boiler is consist of two parts, the boiler body and the accessories which include coal scuttle, the chain grate stoker, base steel and the furnace wall. The boiler is assembled expect the midfeather when it is leaving the factory with economizer and duct furnace.
2.The burning part of the boiler adopts the light chain grate. There are six independent air compartments under the fire grate and air registers placed at the both sides of the air compartments. So that the air can come into the air duct by the blower in the base, then in the independent wind room.
3.There is an electric control cabinet that equipped with boiler. The cabinet includes indicator of the thermal parameter, induced and forced draft fan, control buttons of the electric actuators, and over-temperature alarm device of the auto water feeder.
