✦ Synopsis

03 Gaseous fuels (derived gaseous fuels) char re-supply line. which provides char recovered from the char recovery apparatus. The last component is a steam supply line that connects with the char resupply line for supplying the steam that mixes with the oxidizer. 00/00138 Efficiency of a combined gas-steam process Tuma. M.

The equations for the determination of the overall energy and exergy efficiency of a combined gas-steam cycle process are discussed in thl\ article. The co-generation in the gas and the steam cycle, the reduction of power due to increasing the heat flow in the steam process. the supplementary firing at the gas turbine exhaust, the heat recovery boiler efficiency a\ well a\ the heat exchanger efficiency in the gas and steam cycle were taken into consideration.
'The thermodynamic derivation, the calculations of a typical example. and graphic diagrams are pretented in the rc\ults \ectlon.
