The research object is a novel heat collector installed on the surface of the rotary kiln

which is used for waste heat recovery from the kiln. The experimental and numerical calculation methods are used to analyze the flow and heat transfer characteristics of this equipment. In the process of experimental research

one radiant type heat collector and two coupled type heat collectors are investigated to study the influence between the variation of outlet water temperature

outlet pressure and flow mass on the performance of the collector. Numerical calculations are also performed to obtain working performances of the heat collector using Matlab software. Both numerical and experimental results are compared to verify the accuracy of numerical calculations. The changes of the inlet air temperature

inlet air flow rate and kiln body temperature are numerically analyzed. Related results provide data support for the optimization design of the collector and the selection of the online operating parameters.
