Analysis Of Different Retrofit Technology For Heating Supply With High Back Pressure Of 135mw Grade Steam Turbine
2018 3RD INTERNATIONAL CONFERENCE ON AUTOMATION, MECHANICAL AND ELECTRICAL ENGINEERING (AMEE 2018)(2018)
Abstract
There have nine 135MW grade pure condensing units or extraction condensing units with high back pressure heating in Shandong regional power grid. Four retrofit schemes were used on these nine 135MW grade condensing units. In this paper, the characteristics and renovation content of four retrofit schemes are listed. Through thermal performance test, the economic indexes after reform have been obtained and analyzed. For the unit retrofitting low-pressure (LP) cylinder flow part, its LP cylinder efficiency is the highest. By the reason of influence of the heat load, circulating water flow and retrofit scheme, four units should operate with the extraction steam during heating period, which resulting in the lower power capacity and higher heat consumption rate.
