在大型、连续的现代化化工厂设计中,热电联产的总能设计值得注意。热电联产总能设计概念示意见图1。其工艺过程从热端公用系统需热为Q_入,向冷端公用系统排热为Q_出,同时需要功为W,W可由热机提供。热机本身从热端公用系统需热为O,向冷端公用系统排 In the large, continuous modernization of chemical plant design, the total design of cogeneration is worth noting. CHP total energy design concept shown in Figure 1. The process from the hot end of the public system needs heat for the Q_ into the cold side of the common system for the heat Q_ out, at the same time need to work for the W, W can be provided by the heat engine. The hot machine itself needs hot heat from the hot-end utility system to O, to the cold-end utility system
