Аннотация

The problem of the gas turbine blanding unit protection from the solid phase deporsition on it is discussed here. The basic causes that encourage the intensity of the deposits growth are indicated. In particular, the regular formation of large conglomerates of a solid phase in a high-temperature gas flow is one of such causes. The formation of such conglomerates takes place even when the air filters of fine cleaning are presented. It has been shown that in these conditions the gas film cooling that is formed by two opposing air jets which flow along a front blade edge can serve both a heat and a dust protection at the same time.
