SU10167A1 - Device for heating the air supplied to the oil furnace - Google Patents

Description

The present invention relates to a device for preheating the air in the steam engine oil furnace inflow, and aims to eliminate the harmful voltages that occur naturally when cold air enters the furnace and leads to a breakdown of the combustion system with subsequent leaking of the fire tubes.

In FIG. 1 schematically depicts the specified device in the application to the oil furnace of a steam locomotive in a longitudinal vertical section; FIG. 2 is a section along the line AB in FIG. one; FIG. 3- tubular lattice; FIG. 4 is the same device of a modified form of execution in a longitudinal vertical section; FIG. 4 in plan and FIG. 5 is a modified form of the embodiment of the fixture shown in FIG. 1.

In order to preheat the air supplied to the oil furnace of a locomotive, a refractory threshold 3 is arranged on the bottom of the blower, separated from the furnace space by a conventional vault 2 (Fig. 1) in order to bring air closer to 2 through the pipe 3; In the socket 4 of the latter, a coil 14 (Fig. 1) has a tube or a grating 14 (Fig. 3) for passing steam through them.

In the second embodiment of the form for producing this device, indicated in FIG. 4 and 4, a zigzag channel 6 is formed in the ash pan with refractory masonry 5, through which the air coming in through pipe 3 is conducted into the firebox under the roof 4, located on the side of the locomotive tube sheet.

The modification of the fixture shown in FIG. 5 is that the nozzle 5 is placed in the firebox under the tube sheet and the arch 13 is located near the wall of the firebox opposite it.

The subject of the patent.

1. The adaptation of dd heating of air supplied to the oil furnace of a steam locomotive, characterized by use in a fan, separated from the furnace space by a conventional roof 2 (Fig. 1), a refractory threshold 3 on the bottom of the bed, in order to possibly bring it to the roof 2 through the pipe 3 air.

2. Application of the pipe 3 (fig. 1) of the coil 14 or the tubular lattice 14 (fig. 3) described in section 1 of the fixture 4 in the socket 4 for passing steam through them.

3. The form of implementation described in paragraph 1 of the device, characterized in that the ash pan is formed

refractory masonry 5 (figs. 4 and 4) i zigzag channel 6 through which the air coming in through pipe 3 is led to the fire chamber under the roof 4 located on the side of the pipe grid of the locomotive.

4. Modification of the fixture described in paragraph 1, characterized in that the nozzle 5 is placed in the firebox under the tube sheet (Fig. 5), and the arch 13 opposite to the wall of the fire chamber located opposite it.
