Abstract

The invention relates in particular to those compact, mobile thermal power stations with a capacity of less than 6 M.W. The peculiarity of the process is that prior to the addition of superheated steam to a steam-powered helical mechanism, the steam is injected with water at the rate of 'D', as defined by the equation: D ⊃= (i'- i')QΠ/(C(ts-to) + r), where i',i' respectively represent the steam enthalpy in superheated and saturated form, given that P-const, kcal/kg; QΠ - rate of flow of steam, kg/s; C - heat capacity of the water, kcal/kg °C; r - heat of evaporation; ts - boiling temperature; to - temperature of the injected water prior to injection. The evaporation of the injected water causes the temperature of the superheated steam to drop to the level at which steam is transformed into a wet state.

The great amount of water in the country has a favorable effect on the operation of the transmitter, which contributes to the increase of its EPA. Consumption of this product requires a larger share of the charger, which means that there is a large gap between the charger and the consumer, which is not subject to loss. A lower temperature of wet steam, in comparison with the previous one, does not cause a larger thermal expansion of the components and does not lead to jamming of the mouth.

In this case, it is necessary to reduce the pressure of the disengaged (Fig. 2) or the humid (Fig. 3) steam of a size that can be separated from a range of 5-20 atm. This is achieved by discharging the product by spraying it with water or humid ity when spraying it with dry water. In this case, the vapor pressure decreases, its enthalpy remains unchanged, and the entropy increases. In general, a humid steam tempera- ture device is clever, and the process is unchanged.
