Abstract

Invention m. used to clean steam vaporizer of steam turbine power plants. The purpose of the invention is to increase the washing efficiency in a wide range of steam loads. As the load increases, a perforated sheet 4, made with peripheral flanging 5, is lifted, opening openings 6 for the passage of steam in sheet 1, i.e. steam at all loads is washed in the water layer located in the gap between sheets 1 and 4, and in the water layer on the upper perforated sheet 4. The required level of flushing water is provided by vertical partitions 3 with stops 7. Excess washing water is discharged through the drain pipes 8.

The invention relates to a power system and can be used to clean steam evaporators of steam turbine power plants.

The purpose of the invention is to increase the efficiency of flushing in a wide range of steam loads.

FIG. 1 depicts a steam bleeder; in fig. 2 is a view A of FIG. one.

The steam industrial device contains a lower perforated sheet 1, divided into cells 2 by vertical partitions 3, installed immobile under the perforated sheet 4 made with peripheral flange 5, and the apertures 6 of the perforated sheet 1 are arranged offset from the openings 6 of the perforated sheet 4 The upper perforated sheet 4 is made of several parts, each of which is installed in the corresponding cell of the lower sheet 1 with the possibility of limited vertical mending along the partitions 3, which are made integral with interstitial cells 2 and provided with stops 7, interacting with parts of the upper sheet 4 in their extreme position. On the periphery of the perforated sheet 1 are the drain pipes 8.

Steam booster device- melts as follows.

As the load increases, the hole sheet 4 rises, opening the holes 6 for the passage of steam in sheet 1.

Thus, at all loads, the uninterrupted operation of the device, i.e. steam at all loads is washed in the water layer located in the section between sheets 1 and 4, and the water layer on the upper perforated sheet 4. One

temporarily due to the fact that the holes of the perforated sheets 1 and 4 are not coaxial, the steam jets emerging from the holes of the sheet 1 are deflected, as a result of which moisture is separated from the vapor drops. The necessary level of wash water is provided by vertical partitions 3 with stops 7. Excess wash water is discharged through the drain pipes 8.

Thus, steam of guaranteed quality is achieved. load range from 0 to 100% of the nominal due to the provision of non-lethal operation of the device and additional separation of moisture at the time of steam passage between the perforated sheets 1 and 4.
