Loop Analysis Method for the Numerical Calculation of Hydrodynamic Characteristic of Hot Water Boiler with Natural Circulation

In this paper,based on the hydromechanics and principle for hydrodynamic calculation of boiler,the loop analysis method for the numerical calculation of hydrodynamic characteristic of hot water boiler with natural circulation is presented,which can calculate the flux water of in every tube in the boiler.The equation groups of the loop analysis method are deduced and programmed.In addition,the hydrodynamic characteristic of two hot water boilers with natural circulation is calculated and analyzed by both of the loop analysis method and the Hydrodynamic Calculation Method for Hot Water Boiler(JB/T8659-1997),which validates the correctness and practicability of the loop analysis method.
