Analysis of energy efficiency by replacing the throttle valve with variable speed drive condensate pump from E.C. Turceni

摘要

This paper analyzes the energy efficiency of replacement of the existing scheme of adjusting the flow of condensation from a group of 330 MW of CHP Turceni using a variable speed drive system with one pump. For this purpose the actual energy consumption is compared with the values resulted from the energy balance of variable speed drive system. Two types of drive systems are analyzed: the one with frequency converter and MV motor (6 kV), with that with frequency converter and LV motor (690V).
