To optimize the thermodynamic design of an oil-fired smoke-tube steam boiler, optimized independent variables, relevant variables and objective functions were analyzed and determined on the basis of a thermal equipment optimization theory. In connection with a thermodynamic design process the intermediate variables in the objective functions were solved. The constraint conditions of optimization were determined and a complete mathematical model of optimization was set up. Furthermore, a computer program was prepared to solve the mathematical model. The results of optimization of a typical oil-fired smoke-tube boiler indicate that the optimization model and the computer program for mathematical solution are effective and practical for engineering applications.
