WebThis reduces plant operating costs and also helps to avoid thermal shock to the boiler metal when the feedwater is introduced back into the steam cycle. Boiler. Once this water is inside the boiler or steam generator, the process of adding the latent heat of vaporization begins. The boiler transfers energy to the water by the chemical reaction ... WebHere we highlight four key areas for improving our approach towards understanding plant heat stress responses. First, although the term 'heat stress' is broadly used, that term encompasses heat shock, heat wave and warming experiments, which vary in the duration …
