Design for Double Drum Horizontal Type Chain Grate Boiler SHL20-2.45/400-WⅠ
Abstract：The demand on Security and economy on energy of industry production has become important topic attended by society with development of native economy. The boiler is made up of many department, include drum , superheater，air-preheater, economizer and so on. The theme of this document is to design a stream boiler, whose type is SHW20-2.45/400-WⅠ，The boiler is double-drum natural circulation steam boiler. around the furnace are water walls, To ensure the good and continuous ignition in the furnace, I take a high and short front arch, shile the back arch is low and long. Behind the furnace is the steam superheater. There are dense tube nest between the two drums,which compose the main heat-delivery surface. In the back stake flue, I set the economizer and air-preheater. Set the economizer to decline the tenperatuer of the stack gas and improve the efficiency in the furnace and set the air-preheater to strengthen ignition and firing, meantime to decline the temperature of the stack gas and improve the efficiency in the furnace. The design fuel is the number one anthracite, whose lower radiation value is 18187kJ/kg. Throughout the design process as a technical support for the thermodynamic calculation, strength calculation and the smoke wind resistance calculation. To enable small boiler compact structure, most of the heating surface are installed in the hearth, meanwhile, we should also ensure that there is some hermetic to ensure that within the vacuum chamber combustion. Using CAD, completed a total map boiler, furnace wall map, the map on the drum started, noumenon map, gather box map.
Keywords：steam boiler; boiler design; thermodynamic energy calculation；the smoke and breeze resistance calculation
