FIELD: machine building.
SUBSTANCE: here is disclosed system of steam generation (20) consisting of first cylinder (26), second cylinder (28) and eductor (32) with suction orifice (34), movable orifice (36) and outlet orifice (38). The eductor receives continuous supply of vaporous uranium hexafluoride from the first and/or the second cylinder; also, the eductor directs a continuous flow of uranium hexafluoride via the outlet orifice. Further, the steam generating system consists of conversion reactor (30) and of multitude of valves (46, 52, 56, 60, 66, 69) for control over the flow of vaporous uranium hexafluoride in the system of steam generation including at least one controller (76) of supply coupled with the first supplying line (44, 50, 54). The controller directs the flow of vaporous uranium hexafluoride into eductor (32). At least one supply controller (78) of the said system is connected to second supplying lines (58, 64, 68) for control over flow of vaporous uranium hexafluoride into the eductor. Controller (76) continuously controls rate of the flow and steam pressure, facilitating uninterrupted steam flow into the eductor. The system of steam generation for directing uranium hexafluoride from the cylinder consists of the first cylinder, the second cylinder, the eductor, the controller of the suction flow for monitoring and control over the flow entering the suction orifice, of the controller for monitoring and control over the flow entering into the supply orifice, of multitude of the first valves directing the flow of vaporous uranium hexafluoride from the said first cylinder to the suction orifice and/or supply orifice, of the multitude of the second valves directing the flow of vaporous uranium hexafluoride from the said second cylinder to the suction orifice and/or supply orifice, and of the controller for directing the flow of vaporous uranium hexafluoride from the said first and second cylinders. Notably, the controller of the suction flow continuously governs rate of the flow and steam pressure facilitating uniform flow of steam into the eductor. The controller of the suction flow sends a signal to commence second cylinder heating. Multitude of valves govern the flow of vaporous uranium hexafluoride through the system of steam generation so, that the said eductor receives continuous supply of vaporous uranium hexafluoride from the first and/or the second cylinders, owing to which it directs a continuous flow of vaporous uranium hexafluoride through the outlet orifice.
EFFECT: continuous flow of steam directed into conversion reactor; reduced delay or dead time of conversion process and increased speed of operation of whole system.
