SU10685A1 - Steam boiler - Google Patents

Description

The proposed locomotive boiler is provided with a beam of spirally bent smoke-fired pipes, whereby, in order to improve heat transfer, this} beam is attached to the beam by an eccentric drive on the axles of the wheels of the engine.

In FIG. 1 schematically depicts a longitudinal vertical section of the proposed locomotive boiler; FIG. 2-part of the modified smoke tube.

In two hollow discs b c c (fig. 1) spiral-bent smoke tubes are curved. Both discs are also provided with hollow pins e and ei open at the ends, which are movably fixed in C 1 and the wall 1 of the fire box a and the corresponding wall of the smoke box 1 of the locomotive. Combustion products from the combustion chamber are directed through the pin hole e into the cavity of the disk b, from where they come through the spiral-bent smoke tubes into the disk cavity and through the hole of the pin e into the smoke box of the locomotive. In order to improve heat transfer, a rotational motion is imparted to the entire beam e of the fire tubes, which is achieved by an eccentric drive from the axles of the wheels of a steam locomotive, through means of a crank pin drive gear 5, o, m, or bevel wheels 5

and Sj.

In the modified boiler device, instead of smooth spiral pipes, spiral pipes are also arranged, but formed from a series of interlocked ayu plate elements (Fig. 2), with these pipes being assembled so that the plane of arrangement of the plate elements are perpendicular to the axis the boiler so that, when the beam of the fire tubes are rotated, their plate elements do not exert their influence on the circulation of water in the boiler.

The subject of the patent.

1. A steam boiler, characterized by the use of a beam of spirally bent smoke tubes, capped into two hollow discs with hollow trunnions open at the ends, which trunnions are movably fixed in the glands of the fire box wall a and the corresponding smoke box wall, and are intended to guide products burning from the combustion chamber to the chambers of the smoke box, in order to improve the heat transfer,

one

The beam d is attached to the rotational movement from the eccentric drive on the axles of the wheels of the locomotive through the connecting rod crank gears n, m, l and bevel gears.

2. Modification of the boiler, described in paragraph 1, characterized by the use instead of smooth spiral pipes, -

spiral pipes, formed from a series of interconnected hollow dish-shaped elements (Fig. 2), the plane of arrangement of which dish-shaped elements are installed perpendicular to the axis of the boiler, in order to prevent the helix from acting on the water circulation in the boiler.
