Energy and exergy analyses are used to evaluate the Zero emission coal (ZEC) system. Energy and exergy losses in each unit of the system are calculated and depicted with Sankey diagrams of energy flow and exergy flow when the system operates at a benchmark condition. Sensitivity analysis is...

An LPE (low-pressure economizer) based waste heat recovery system for a CFPP (coal-fired power plant) is investigated thermodynamically. With the installation of LPE in the flue before the FGD (flue gas desulfurizer), the heat contained in the exhaust flue gas can be recovered effectively and...

This paper presents a case study of recovering the waste heat of the exhaust flue gas before entering a flue gas desulphurizer (FGD) in a 600 MW power plant. This waste heat can be recovered by installing a low pressure economizer (LPE) to heat the condensed water which can save the steam...
