【Abstract】 According to the principle of "Three transmissions and one reaction", the authors established the mathematical model for 4-stage pre-heater cyclones with equation groups based on gas balance, material balance and heat balance, to which solution can be got by means of Gauss Method. Practice shows that this method can well represent real production process, and have opened up new ways for optimizing preheating system design.更多还原
