Benefits of molten salt for heat transfer and thermal

Trough collectors heat a synthetic oil HTF to about 390°C. When the sun is shining, the hot HTF may be diverted to a heat exchanger for charging the molten salt TES system, and it may be used immediately to produce steam by flowing through a series of heat exchangers in the power block.

Developments in co-generation in sugar mills - EE

The back pressure steam cycle is widely used in sugar mills. This uses a back pressure turbine (BPT) to generate electricity and the output of the turbine is fed to the process steam line. (Fig. 2). In this case the sugar process determines the quantity of steam that is produced by the boiler, as there is not a steam condensation system.
