3、calculations, boiler heat calculation balance, boiler furnace,anti-thermal residue management and other computing devices.In the thermal calculation, firstly,we use the methods of assumptions, and then check them and successive approximation to calculateing .Simultaneously,we determine the size of f

4、urnace and related components and layout of various heating surface.In the design, through a lot of information about the chain boiler, this boileris are widely used in the modern industry, and the technology is more and more ripe, so it provides a helpful program for the subject-based chain boiler design.this design also includes mission statement ,calculation specifications,the CAD chart of the boiler body , air preheater and economizer. Keywords: chain boiler ; furnace ;thermal calculatio
