Under the guidance of energy conservation and emission reduction policies,to ensure the achievement of energy conserva-tion and emission reduction goals,some gas boiler systems adopt independent cycle system of energy-saving device to achieve the re-covery of waste heat from tail gas of the boiler.In order to theoretically grasp the characteristics of this circulating system,two meth-ods are used to study the system such as measuring separately the heat exchange of the energy-saving device and calculating the heat ex-change of the energy-saving device and its system as a whole.It is known that the method of measuring separately the heat transfer of energy-saving device can obtain more accurate test results,but the test and calculation process is more complicated.Considering the energy-saving device and its system as a whole for calculation,on-site work is relatively simple,but it needs to consider the heat stor-age and dissipation capacity of the water tank.The measurement and calculation of thermal parameters of independent cycle system of energy-saving device is important in boiler energy efficiency test,which can directly affect the measurement results.
