Research and Application of New Condensing Extraction Backpressure heating technology of 330 MW unit

Abstract

This paper introduces the retrofit scheme of the New Condensing Extraction Backpressure heating technology, and the technology is recommend for use by comparing and analysing the combined heat and power system based on a 330MW unit retrofit. After improvement, the heating capacity has been Obvious improved, the generation power has been greatly reduced and the capacity of peak load regulation has been significantly improved, which can not only realize the thermoelectric decoupling, but also obtain the remarkable economic benefit.
