Dependence of changes in pressure of superheated steam upon reducing heat drop in the throttling regulation of steam turbines

摘要

Regulation of the steam turbine can be achieved by optimal, reliable and safe operation. Power regulation adjusts the operation of the steam turbine load current, i.e., it changes the thermal drop (throttling control) or quantity of steam (nozzle control group). An analysis of the throttling regulation reveals the turbine power dependence on the pressure and the supplied amount of steam, and shows the losses due to a pressure drop in the aforementioned regulation.
