A biflux heat-exchanger has been series-connected before the reheaters on side of the "cold steam" ( 603 – 623 K ) which […] Due to a suitable heat convection coefficient and temperature gradient, the biflux heat-exchanger ensures a highly […]

Of further interest is the use of heat exchange between the high - pressure and reheat steam outside the flue gas flow (bifluxes) to avoid permanent reheat spray water flow and to increase the efficiency […]
