Description

The subject of the invention is a mobile steam boiler consisting of sections, each of which is made with one upper and one lower collectors interconnected by vertical pipes.

A distinctive feature of the described boiler is its rigidity, necessary for mobile boilers, and the simplicity of the device, which is achieved by welding individual sections so that the upper and lower headers form closed rectangles with common steam and, accordingly, water spaces, and the connecting headers are vertical pipes form the walls of the furnace. To regulate the power and efficiency of the boiler, which is achieved by changing its heating surface inside the contour forming the boiler, several sections are used that make up either a double-lined screen or a convective heating surface, and the flue gases washing the convective surfaces can be directed through the boiler sections both in parallel and in series. In addition, an air or water economizer can be installed at the boiler, which will increase the efficiency. installation.

The steam boiler is designed for mobile installations of low power and consists of several sections, which can be located both on the outer contour and inside it. Each section / is made with one upper and one lower collectors 2 and 3 interconnected by vertical pipes 4 (Fig. 1, 2). In order to simplify production and give the boiler the rigidity necessary for mobile boilers, the separate sections are welded together so that the upper and lower headers 2 and 3 form closed rectangles with common steam and, accordingly, water spaces, and the connecting headers 4 form the walls of the furnace (Fig. 3, 4, 5, 6, 7 and 8).

In order to control the power and efficiency of the boiler by changing its heating surface inside the contour forming the boiler furnace, the installation of several sections is used, which constitute either a double-lighted screen (Fig. 9) or a convective heating surface (Fig. 10 and 11) on leaving the furnace 5, they can be directed along convective surfaces as parallel (Fig. 10), hook and in series (Fig. I). In the latter case, the boiler will be less productive, but more economical, and in the first case, vice versa.

In order to increase the efficiency Installations in the boiler are applied to water or air economizers 6 and 7, which are enameled in the contour of the convective sections of the boiler (Fig. 7, 8, 9 and 12).

From the outside, the boiler is closed with a flame 8, protected from the inside by heat-resistant insulation 9. The casing can be double-layered, with a lumen for the passage and heating of air entering under the grate.

There are rotary valves to remove the ash deposited in the flue ducts. 10. Fuel is poured into the door. Instead of the door, there may be an oil burner or a gas burner (Fig. 7 and 8).

The feed tank 12 of the feed water is set up thin to form its ceiling (Fig. 7).

The flue gases, the outlet from the furnace located in chamber 5, wash convective surfaces on their way, and they can be directed along sections of the boiler both in parallel and sequentially, after which they pass through slot 13 into chimney 14.
