high temperature and high pressure boiler reheat temperature

Supply Air Temperature - an overview | ScienceDirect Topics

A large temperature difference will result in a high acceleration of the supply air and therefore a reduced protected volume, especially when a textile tube is used as the inlet air unit. It is also important to avoid high temperature differences because of the risk that drafts may cause discomfort for workers.

Tankless water heating - Wikipedia

Tankless water heaters — also called instantaneous, continuous flow, inline, flash, on-demand, or instant-on water heaters — are water heaters that instantly heat water as it flows through the device, and do not retain any water internally except for what is in the heat exchanger coil. Copper heat exchangers are preferred in these units because of their high thermal conductivity and ease
