SU25951A1 - Evaporator - Google Patents

Description

In the proposed evaporator, water from the pressure feed tank enters flat wavy-curved pipes, which are washed with hot gases, and the resulting steam is collected into steam collectors placed above the waves, connected to a common steam discharge pipe.

In FIG. 1 shows a vertical section of the evaporator; FIG. 2 - view from above.

When water is pumped by a pump with a calculated flow rate per unit of time, water from the hermetically sealed feed tank 1 enters flat, wavy-curved pipes 2, above the waves 5 of which, covered with a thin layer of water, are placed steam collectors 3 connected to a common steam collecting pipe 7. Pipes 2 they are washed with hot gases along arrows b and because of the thinness of the water layer on the waves of 5 tubes, the latter quickly evaporates, turning into steam, which

from the steam collectors 3 and is discharged through the pipe 7. Locating several such batteries of evaporators one above the other, each with its own supply tank 1, and carrying hot gases from the same furnace vertically through all these batteries, one can achieve significant steam removal, and The gases, washing the vapor spaces of the steam collectors 3, will at the same time overheat the steam, increasing its heat content, which reduces the heat loss in the exhaust gases.

The subject matter of the invention.

An evaporator, characterized by the use of flat, wavy-curved water pipes 2, which are directed by hot gases, directed from a pressure feed tank 1, above which waves are steam receptacles 3 connected to a common steam discharge pipe 7.
