Развитие методов снижения выбросов двухфазного криогенного продукта при испытании энергетической установки

Abstract

Technological processes and levels of losses of a cryogenic product in a complete cycle from the moment of his delivery before termination test of power installation are certainly situated at its operational development. The purpose is to decrease the cost of test realization. Tasks on minimization and use of losses of a cryogenic product are put at realization of tests. Has been developed algorithms and techniques to define losses of a cryogenic product in various technological processes which allow to optimize realization of power installation test. On the basis of the developed techniques, the accounts are executed and the relative losses of a cryogenic product are certainly depending on used thermal isolation of cryogenic pipelines and fixture, initial and final temperature of system of submission, pressure of a cryogenic product during cooling, material of pipelines and kind of a cryogenic product (hydrogen, nitrogen, oxygen). Has been offered methods and technical decisions on to decrease and use emissions of cryogenic product, depending on their charges, in technological processes at realization of tests of power installations. Has been given the recommendations for parameters to decrease losses of a cryogenic product and conditions at realization of technological operation of pipelines cooling, units of the stand and power installation at its test. The work is intended to the designers and technologists of test stations.
