Results show that bed pressure in relation with the thickness of bed material influences fluidization state directly.
Raise bed pressure means heat storage of bed material is increased, which is of benefit to the uniform of bed temperature.
Literatures [4, 10, 11] find that when raise the volume of circulating ash, more bed material will be blown to dilute-phase zone, which means more quantity of heat is taken to this area, bringing more uniform temperature distribution of the whole furnace.

Materials and preparation of samples For the production of test bodies, the composition of quartz sand and FBCFA was used as a source of siliceous materials, while 20 percent of weight of sand was replaced by FBCFA.
Basic chemical composition of the raw materials is displayed in Table 1.

After the flood control project is completed, the living and work environment of the people on both sides of the river can be greatly improved; during the flood season, it's not necessary to employ great manpower and material resources for flood control; meanwhile, it can reduce the possibility of collapse of buildings, casualties, and industrial and agricultural production halts and reduction of output caused by the flood disaster, so it is a powerful guarantee for the social stability and prosperity of Yibin.
