Rankine cycle - Wikipedia

The thermodynamic characteristics of the single- and double- reheat boilers under off-design working conditions and during transient processes are compared from the perspective of energy and exergy. Results show that the heat absorption and exergy storage of re-heaters in the double-reheat boiler is ~1.4 and ~2.0 times those of the single

Indeck Heat Recovery Steam Generators (HRSG) | Indeck

The reheating of cold primary air seems, on the surface, to be a wasteful practice in terms of optimum utilization of energy resources. There are many situations, however, where it is not only necessary, but It is recognized that non condensing boilers require a high entering water (return water) temperature to avoid hocking?the

Application of high steam parameter for High sulfur coal

The reheat cycle was first introduced in the 1920s, but was not operational for long due to technical difficulties. In the 1940s, it was reintroduced with the increasing manufacture of high-pressure boilers, and eventually double reheating was introduced in the 1950s. The idea behind double reheating is to increase the average temperature.

Using Reheat Cycles - Northwestern University

In this reheat cycle, steam is expanded isentropically to an intermediate pressure in a high-pressure turbine (stage I) and sent back to the boiler, where it is reheated at constant pressure to the inlet temperature of the high-pressure turbine. Then the steam is sent to a low-pressure turbine and expands to the condenser pressure (stage II) .

Reheat Cycle Advantage in Thermal (Steam) Power Plant

In the reheat cycle, the steam is extracted from the suitable point in the turbine and is reheated with the help of the flue gases in the boiler furnace. The main purpose of reheating is to increase the dryness of the steam passing through the lower stages of the turbine. The dryness fraction coming out of turbine should not be less than 0.88.

IMIA WG paper 95(16) Supercritical Boilers

reheat type supercritical units were also introduced. However, because of their higher capital cost and rather complicated reheat temperature control, the single reheat type boiler configuration has been preferred. A history of the upgrading of steam conditions of domestic supercritical boilers supplied by BHK is shown in Figure 1[1]. Over the
