Calculations and Design for SHL10-1.25/250-W Boiler
Abstract：According to design parameters that has given design and the relevant design information, we make heat calculations and preliminary design calculation on SHL10-1.25/250-W boiler.The main contents include introduction, fuel and combustion 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 furnace 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[10].
Keywords: chain boiler ; furnace ;thermal calculation.
