Investigation of the saturated steam sampling method influence on the sample representativeness in chemical control systems at thermal power plants

Autor: O V Yegoshina, S K Zvonareva

Publikováno v: Journal of Physics: Conference Series. 2088:012052

The most important requirement for sampling is the sample representativeness, which is achieved by the design and location choice of sample nozzle, as well as the speed mode and the presence of sharp pressure drops in the saturated steam flow. The An
