The unmatched gas turbine CHP plant

In general, a gas turbine CHP plant may not exaetly mateh the eleetrieity and heat demands. A plant with a recuperator may meet the heat load (Qu)cg = but not the power load (Wgg Wd= 1) so extra power from the grid is required (Wc) as illustrated in Fig. 9.4. Following a procedure similar to that given in Section 9.2.3 it may be shown [ 1 ] that the performance parameters for the total plant are then
