Development of methods of reduction of emissions of a biphase cryogenic product at test of power installation
The 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 certain in its operational development. The purpose of the study is to decrease the cost of tests. The tasks on minimization and use of losses of a cryogenic product while testing are considered. The algorithms and techniques of the definition of losses of a cryogenic product in various technological processes are developed which allows optimizing realization of a test of power installation. On the basis of the developed techniques, the accounts are executed and the relative losses of a cryogenic product are certain 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). The methods and technical decisions on the decrease and use of emissions of a cryogenic product are offered, depending on their charges, in technological processes at a realization of tests of power installations. For a decrease of losses of a cryogenic product, the recommendations for parameters and conditions are given at realization of technological operation of cooling of pipelines, units of the stand and power installation at its test. The work is intended for the engineers of the designers and technologists of test stations.
