A high-temperature convective radiation heat transfer experimental device and experimental method, comprising a furnace body fueled by coal gas or natural gas, the furnace body is provided with an automatic temperature control device, an air supply device for automatically controlling the air volume, a furnace chamber is provided in the furnace body, and the furnace body The top of the furnace body is vertically provided with a chimney connected to the furnace chamber, the bottom of the furnace body is provided with a vertical fire channel extending vertically downwards and connected with the furnace chamber, and the mobile trolley behind the sample support is vertically provided with a The bracket extends into the furnace cavity to block the baffle of the furnace door. A thermocouple is arranged on the sample bracket. The front end of the thermocouple extends to the sample placement part of the sample bracket, and the rear end of the thermocouple extends to the rear of the baffle. The present invention can adjust the situation of air convection, not only can simulate the working process of blast furnace hot blast stove combustion period and air supply period, test the heat absorption rate of high-radiation coating combustion period and the increase rate of heat release rate of air supply period, but also consider Effect of smoke and air convection. Capable of accurately testing the energy-saving efficacy of high-radiation cladding.
Description
technical field [0001] The invention relates to a high-temperature convection radiation heat transfer experimental device and an experimental method. Background technique [0002] High radiation cladding energy-saving technology is an energy-saving technology that has been widely used in steel, thermoelectric, petrochemical and other industries. In the application of blast furnace hot blast stove, the coating is applied to the surface of the blast furnace hot blast stove lattice brick to improve its surface emissivity, thereby improving the fuel utilization rate and saving energy. However, there is currently no detection method that can accurately test the energy-saving efficacy of high-radiation cladding. The existing high radiation coating heat storage detection method, but because the experimental furnace used is an electric furnace, there is no air convection, only the influence of radiation heat transfer is tested, and the influence of convection is not considered.
