Method for testing contribution degree of various stresses to particle wear in fluidized bed

The invention relates to the technical field of fluidized beds, and particularly discloses a method for testing the contribution degree of various stresses to particle wear in a fluidized bed, which comprises the following steps of: judging the types of stresses borne by a material in a fluidized state, and assuming that the types of the stresses borne by the material in the fluidized bed are mechanical stress, thermal stress and chemical stress; preparing three groups of same materials m0 respectively, sequentially carrying out cold-state test, hot-state test and reaction test for 10 hours respectively, and carrying out cold-state test test and cold-state test wear rate calculation; testing in a thermal state experiment and calculating the wear rate of the thermal state experiment; testing a reaction experiment and calculating the wear rate of the reaction experiment; calculating the contribution degree of mechanical stress; calculating the contribution degree of thermal stress; and calculating the contribut
