摘要
根据动量守恒原理，对液化石油气混空气中压引射器进行热力学分析，并建立了最佳结构条件下中压燃气引射器特性方程。通过实例计算及引射器能量有效利用的分析，了解渐缩喷嘴的使用范围及判定方法。合理使用“拉伐尔”喷嘴，则液化石油气混空气中压引射器对小区供气是可行的。
This paper analyzes mid-pressure gas injectors of LPG/air mixture with thermodynamic principle using the law of conservation of momentum, and establishes characteristic equation of mid-pressure gas injectors under the optimum conditions. By means of example and find out usable range and determined methods of gradually reduced nozzle. It is feasible to rationally use Laval jeti for small district gas supply.
