英语翻译
Three cases were considered,namely:
1.a CHP system,where power is recovered from the
exhaust gases to either a wet steam or ORC system,
from which the heat from the condenser is
transferred to a hot-water heating system;
2.power recovery only from the exhaust gases to
either a wet steam or an ORC system fitted with
an air-cooled condenser;
3.power recovery only in the case where a supply of
cooling water is available.Inthis case,thewet steam
condenser acts as the feed heater–evaporator of an
ORC system that uses R245fa as the working fluid.
Assumed coolant conditions:
Case (i):Hot water entering the condenser at 70 ◦C and
leaving it at 90 ◦C.
Case (ii):Air at 30 ◦C.
Case (iii):Cold water entering the condenser at 20 ◦C
and leaving it at 30 ◦C.
Assumed power plant details are given in Table 1.
