Description

Patent No. 7615 describes a device for cleaning and heating feedwater in 3 locomotive-type boilers, which means that a partition is placed inside the boiler, dividing the water space of the boiler into two parts. There is a cholus attached to the partition, intended to receive feedwater, as well as to collect foam from the surface of the water in the boiler, and connected with a pipe to the bottom of the steam locomotive. Having passed through the mudjack, water enters the heater placed in the smoke box, from which it is fed by natural circulation to the space of the boiler adjacent to the smoke box, from where it flows through the outlet pipes to the main part of the boiler.

In Additional Patent No. 11308, the cholobi placed inside the boiler for feedwater are directly connected by means of a pipe to a thawer, which, in turn, is directly attached to the heating tubes in the locomotive firebox.

In the proposed modified device, the receiving heads for communicating with the tailpipe are provided with pockets formed inside the boiler at its walls and entering through the neck.

in a tail pipe, the discharge pipe of which is provided with a nozzle mounted against the inlet of a conventional device for enhancing circulation.

In the attached drawing of FIG. 1 schematically depicts a longitudinal section of a locomotive boiler equipped with the proposed device; FIG. 2-cross section of the boiler; FIG. 3-horizon its cut; FIG. 4-nozzle: to remove foam.

Zholoby 3, placed in the front part of the boiler and intended to receive dirty foam from the surface of the water, stretch down the side walls of the boiler downwards in the form of pockets 18 (Fig. 1 and 2), which are passed through the bottom wall of the boiler to the boiler; by means of an outlet pipe 12 (figs. 1 and 3), a sieve 8 is attached to the lower part of the casing, a firebox, where the open end of pipe 12: is provided with a nozzle 21 installed against the inlet of a conventional device 22 to enhance circulation. End of feeding pipes 1 from injectors or from the pump of the water heater: attached to the bottom of the pockets 18. For the possibility of flushing the broom 3, the pockets 18 and the sieve 8 without water from the boiler, the pipe 12 is equipped with a stop valve 24 and the inlet

portions of the troughs 3 are provided with valves 23 with a drive discharged to the outside of the boiler in order to stop the foam from entering the troughs before washing them. On both sides of the boiler, opposite the trough 3 and pockets IS-, there are flush hatches 19 and 20.

Through the hatches 19 - inside the cholok 3, the swivel nozzles 25 (Fig. 4), equipped with taps 26 on the external parts, are passed through. Under the influence of the water circulation in the device 22 through the pipe 12, water will be sucked out of the sieve 8, pocket 18 and Zholobov 3. S last with the assistance of cutwater 4 incessant flow will flow into the foam with incrustation and through pockets 18 will be diverted to the shedder 8, where, when passing between partitions 9, scum will sediment due to the slow passage in the aik and calm state flow. The nozzle 21 on the pipe 12, located against the inlet of the device 22, is used, firstly, in order to obtain a slow circulation of water for better sedimentation in scaler 8, and secondly, the device 22 continues to perform - the main purpose, even with a few weakened action. The removal of 3 foams with fatty impurities from the troughs is carried out using the nozzles 25 (Fig. 4).

The subject matter of the invention.

1.Varification of the device for cleaning and heating feedwater in locomotive type boilers as described in patent No. 11038, supplementary to patent No. 7615, characterized in that the receiving chambers 3.3 (Fig. 1-3) are equipped for communication with the surge gear 8 by armans 18, formed inside the latter at its walls and entering through the throat into the burner, the discharge pipe 12 from which is provided with a nozzle 21, mounted against the inlet of a conventional device 22 for increasing circulation.

2. In the device described in paragraph 1, use in the inlet part of the trough 3 valves 23 (Fig. 3), which serve to stop the foam from entering the trough before washing them.

3. In the device described in paragraph 1, the use of rotary nozzles 25 (Fig. 4) passed through the boiler wall into the chutes 3, equipped with taps 16 on the outside parts and serving to remove fat-rich foams from the troughs.
