A thermodynamic analysis of several pressurized

This thesis presents the results of computer modelling of two classes of combined cycle pressurized fluidized bed, coal fired power generation systems. The steam tube and air heater cycles have been proposed for future power stations because of their cost effectiveness and low pollution. The performance of the air heater cycle and seven variations of the steam tube cycle are simulated. The
