Energy analysis and exergy analysis method

Abstract

We mounted the thermodynamic evaluation model by means of the use of the actual dimension parameters of six hundred MW direct dry cooling strength plant in Wuxiang, China. The overall performance, particularly the exergy losses of the unit in addition to its subsystems in particular along with seven parts were acquired no longer most effective at one particular load however additionally at specific masses. We’ve determined that the exergy loss inside the boiler is generally greater than 70% of the whole exergy lack of the gadget, while the exergy loss of the combustion occupies more than 50% of that of the boiler. Therefore, it's far critical to lessen the losses inside the boiler for electricity saving capability development, in particular that of the combustion and warmth switch. on the same time, the cold stop optimization has fairly huge capacity for power saving due to that the exergy efficiency of the air cooling device is pretty low being approximately 5.7% or so. in addition, we've got gotten the primary converting traits of gadget performances in conjunction with the weight alternate, together with exergy loss, exergy efficiency and coal consumption, which were derived from the real-time system performance records according to a massive quantity of measured records in actual time. if you want to make the complete device run greater effectively, it's far cautioned that the unit need to run at the load higher than 350 MW.
