By analysis, comparison, and demonstration, the authors made a choice on the type of burner that burns low- grade oil, for the purpose of finding a way to improve thermal efficiency of this type of boiler, and demonstrated the general structural form of a such boiler. In terms of the structural characteristics of the boiler and the study on heat transfer of heat -conducting oil inside the coils, the authors gave thermodynamic calculation method, coil strength calculation method as well as the boiler strength calculation method for this type of boiler in the light of relevant national standards for strength calculation. The authors also chose and analyzed the flow resistance calculation method for the medium flowing inside the coils, and gave the flow resistance calculation method for the heat-conducting oil in the light of relevant national resistance calculation standards for this type of boiler. Based on the smoke and wind resistance calculation principles, the smoke and wind resistance calculation method of this type of boiler was giverL The boiler was actually calculated using the above-mentioned methods.
