| Summary: | Gas vapor mixture which removed by flow booster from a large-tonnage gas drying installation is represented for the first time by a complex system consisting of dry gases (drying agent, sucked on air) and water vapors (contained in drying agent, sucked on air, evaporated moisture). The author has set up the algorithm connecting leakage coefficients, dimensionless parameters and those measured instrumentally (burner efficiency; amount of damp coal concentrate charged into drying device and dried coal concentrate discharged from balancing chamber; heat rate; heat leakage for material heating with exhaust gases into environment; drying installation efficiency) which are taken as a basis of the technique for calculating raw (dried) concentrate for damp amount evaporated at continuous operation in the mode. |
