查询词典 kerosene burner

In applying high concentration burning technique to improving burning efficiency for pulverized coal burner, for studying the effect of solid flows of different concentration on burning, Euler mathematical model is set up using gas-solid two phase flow theory. The paper describes the low concentration pulverized coal in horizontal primary air pipe. The relationship between the velocity and concentration of gas phase and that of solid phase, and the effect of gas flow velocity on gas-solid two-phase flows, is arrived through calculating the flow field. Reasonable gas flow velocity is proposed.
