| Abstract: | Based on the principle of pneumatic conveying, a correlation is deduced to calculate the pressure gradient of the gas-solid two-phase waste flow in horizontal vacuum conduit with an example given. Discusses the relationship between three key process parameters, ie. , pressure loss, gas flow velocity and the ratio of solid waste to air. As a result, a method is proposed to calculate economically the critical gas flow rate and critical ratio of air to solid. |
