Blowing measures of lowpressure steam pipe of gas steam combined cycle unit

Abstract

Abstract:

Abstract:The steam pipe blowing processes for HRSG of two gassteam combined cycle units with different parameters were introduced and analyzed. Some conclusions were obtained from the analysis are as below. When the gas turbine runs with certain load, it can provide blowing steam with high parameters, and the duration of pipe blowing and the consumption of desalting water can be reduced correspondingly. To arrange the lowpressure steam blowing pipe separately is useful to avoid interaction effect between the highpressure steam system and the lowpressure steam system of HRSG in combined cycle system.The selection of pipe blowing parameters in this paper can be used as reference for similar units.

Key words: Keywords:gassteam combined cycle unit, HRSG (heat recover steam generator), steam pipe, blowing
