As previously mentioned, in order to simulate solid particle breaking and Dusting phenomenon in practical application in industry process better, i.e. solid particle sample, such as coal, semicoke, moulded coal or activated carbon, in burning, gasification and pyrolytic process, due to inter-particle collision, mechanical wear and the breaking and Dusting phenomenon because being occurred by thermogenetic thermal stress effect, the present invention proposes the dynamic thermal stability assay method of a kind of solid particle, and this assay method makes solid particle produce motion phase mutual friction and collision to realize solid particle while solid particle is heated.As total technology design, the thermal stability result that when solid particles such as coal independent consideration sample being remained stationary for being different from prior art and standard, heating sample measures, adding the dynamic analog of the collision to solid particle and friction on the basis that solid particle is heated, the granule better to reflect grain breakage atomization process in actual industrial rolls the factors such as collision and mechanical wear.

On the basis of above-mentioned total technology design, phenomenon for quantitative analysis solid particle breaking and Dusting in above process, on the basis of the thermal stability determination method of existing coal, introduce dynamic thermal stability index as evaluating solid particle efflorescence degree in above process.Dynamic thermal stability mentioned herein i.e. solid sample be subject to the thermal stress effect that high temperature produces produce simultaneously collision, abrasion and keep the character of original granularity, and establish, with this, the mass fraction that a set of sample mass to be retained on testing sieve accounts for original sample and refer to calibration method as dynamic thermal stability.Further, develop a set of Special testing device for this for simulating said process, below will set forth one by one.

For realizing making solid particle produce motion phase mutual friction and collision to realize solid particle while solid particle is heated, better simulation practical application in industry process, can adopt and the solid particle sample of certain particle size is put in the motion such as rotating cylinder or vibrosieve, to follow the motions such as the generation rotation of this motion or vibration, make solid particle follow generation vibration or rolling, between granule and between granule and motion, produce collision and mechanical wear.Specific in implementation below, referring to Fig. 1, solid particle loaded in rotating cylinder 6 and drive this rotating cylinder 6 to rotate, so that solid particle moves in rotating cylinder 6.Use rotating cylinder can the motion intense degree of more convenient control solid particle, control to quantify by rotating speed, thus described motion adopt rotating cylinder comparatively suitable in test.And the heat that solid particle is heated can be from the heat radiation of electric furnace etc., it is also possible to originate from the gas heat carrier etc. in the external world.Referring to Fig. 1, as selectable two kinds of mode of heatings, the rotating cylinder 6 of solid particle can be will be loaded with and put into heating furnace 12 to be heated, and/or in rotating cylinder 6, pass into hot gas so that solid particle to be heated.So, the coal sample in rotating cylinder 6 can be subject to the comprehensive function of inter-particle collision, mechanical wear and thermal stress simultaneously and crush.
