Tsyvenkova N. The approvement of gas producer gasification chamber parameters, that is adapted for vegetal raw material.

The thesis focused on the problem of increasing the efficiency of process of receiving energy from straw by mean of finding out the rational constructive and technological parameters and operating modes of downdraft gas producer gasification chamber, which is used in grain drying technological process. It was developed a mathematical model, which intercoordinates gasification chamber constructive and technological parameters with gas blowing mode and vegetal raw material physical and mechanical parameters. The analysis of this model gave an opportunity to manage the gas producer heat productivity. The main downdraft gas producer gasification chamber constructive parameters and operating modes were grounded by theoretical and experimental research. There was defined a condition under which gas producer heat productivity is maximized. There were investigated the influence of straw humidity, air amount, which is necessary for gasification process, and diameter of tuyeres positioning, which is regulated by moving the tuyere along its axis, on gas producer heat productivity.
