The technique of spouted rotating-fluidized bed imports tangential rotationalflow to normal spouted bed which enhanced the transmission process between gas andparticles.

And the particle diffusion coefficients of particles in different areas of this internal circulating fluidized bed are calculated.

Based on the calorific value of municipal solid waste, its physical composition analysis and the cold state test results of fluidized bed air distribution the authors have conducted the study of an internal circulating fluidized bed (ICFB) combustion system.

In this paper, The combustion temperature stability in the dense phase bed zone and temperature distributions in the incinerator have been studied by adjusting mass of processed waste, types of waste and particles thickness of bed in the internal circulating fluidized bed (ICFB).

In this paper,aimed at the peculiarity of military products,two new ways of finishing are presented after the processing principle and the main structure are expatiated,which are compulsive spiral flow way and magnetorheological fluid method.

By means of analysis of the influence of barrel inner surface on firing process and firing precision,3 kinds of exact manufacture method were proposed,they are compulsive spiral flow method,high pressure water jet ringed flow method and magnetorhelogical fluid method.

In this paper,the compulsive spiral flow ways used to finish the inner surface of barrel are presented,and the characters of flow field of the equipment in finishing are analyzed.
