A superheater is a vital part of the a boiler system that is used to increase the overall efficiency of a thermal power plant. More specifically, it is a device which converts wet steam (saturated steam) into dry steam as dry steam contains more thermal energy.
Thin-lipped bursts also occur in super heater tubes when steam flow is insufficient, when deposits restrict flow, or when tubes are blocked by water due to a rapid firing rate during boiler start-up.
Nov 22, 2019 · A superheater is a device found in steam boilers that is used to convert wet, saturated steam into dry steam. Superheaters are a very beneficial part of the steam cycle, because dry steam contains more thermal energy and increases the overall efficiency of the cycle.
Boiler superheater pada awal kemunculannya digunakan pada kereta api uap. Dan selanjutnya banyak dipergunakan untuk kebutuhan pembangkit listrik tenaga uap.
