Development of a Procedure for Starting Up a 300-MW Power-Generating Unit with a TGMP-114 Boier under a Siding Pressure at the Kostroma District Power Station

摘要

The results of experimental start-ups of a 300-MW supercritical-pressure power-generating unit with a TGMP-114 boiler under a sliding pressure throughout the steam-water circuit without using outside steam are discussed. The reliability of the retrofitted starting scheme of the power-generating unit was estimated. The algorithm for its start-up was developed. The reliability of the heating surfaces of the given boiler under the conditions studied was demonstrated.
