Co-firing characteristics of corn stalk and stone coal in different proportion were investigated by thermal gravimetric analysis. The results showed that corn stalk can improve the ignition and combustion of stone coal. The agglomeration experiments on corn stalk were made in a bench-scale bubbling fluidized bed with quartz sand as bed material and stone coal ash as additive. The results indicate that stone coal ash can inhibit agglomeration of bed material particles at temperature of 900℃. Agglomerate of blends was analyzed by means of scanning electron microscopy, energy-dispersive X-ray, and the bed materials were analyzed by means of X-ray fluorescence. Analysis showed that aluminum element and iron element in stone coal ash can react with alkali compounds and eutectics with low melting point, form a covering layer with high melting point on the surface of biomass and quart sand particles, thus inhibit the forming and transfer of low melting compounds.

In this dissertation the"Penalty"finite element method was employed to compute the velocity of the three-dimensional flow of power-law fluid in a profile die. In order to decrease the needed computer memory and raise the stability of numerical simulation, a set of decoupled methods such as PFEM, pseudo-body force method and transformation of momentum equation to the elliptic equation was developed to establish the general finite element equations to compute the distributions of velocity and viscoelastic stress of the three-dimensional viscoelastic flow of the Phan ThienTanner fluid in a profile die. During numerical simulation of the extrudate swell of the PTT fluid, the flow in the die and out of the die was analyzed separately, which demands less computer memory. The key techniques used in numerical simulation of the three-dimensional extrusion from dies such as decision of boundary conditions, creation of initial velocity field, selection of penalty factor, high Weissenberg number problem , regeneration of the free surface were studied in detail.
