Description

13. The proposed steam injection water preheater, equipped with a double steam supply, is used for supplying steam and water to the corresponding nozzles with a piston distribution vessel; body spools, the common stem of which is associated with a spring iplavk, intended for water level fluctuations in the vessel holding the heater to move said spools to open or close the channels supplying steam and propellant nozzles to the nozzles by mixing the last heated water for feeding the boiler.

In FIG. 1 schematically depicts a vertical section of a heater; FIG. 2 a section along the line A Nna of FIG. one.

The heater device is TV next. The vessel 11 (Fig. 1 and 2), servants burning for supplying steam and water to the corresponding nozzles, is equipped with a doubled distribution gold 7, the common stem 8 of which is associated with a spring float 9. The latter, as well as "the entire heater In general, the order inside the vessel 1, into which water is heated through the nozzles 4, 5, 6 mixed with the iiapOM, is gone, and further through

I pipe 13 into the boiler. Cold water at j this enters the preheater through j pipe 3, and steam through pipe 2. I When the preheater acts, starting with water level fluctuations in vessel 1, for example due to the heated water leaving the pipe 13 into the hotel, the float 9 is lowered, whereby the spools 7 are also moved down, opening channels that supply steam and water to the nozzles. At the same time, the cold water entering the heater through pipe 3 gets the opportunity through channel 12 to get into nozzle 6, and the steam entering through pipe 2 gets into nozzle 4 and, through channel 10, into nozzle 5. As you can see, water in order to receive; heating by mixing it with steam. is exposed to the latter twice: inside the nozzle 6, steam escapes from the nozzle 4, and when this mixture leaves the vessel 1, the effect of the steam in the nozzle 5 is added. Upon satisfying the need for heated water, the level in the vessel 1 rises, the float 9 rises, as a result of which the spools 7, also rising, close the channels 10 and 12, and the heating of the water is stopped.
