Description

The transportable water-heating boilers with pipe shields are known, including a firebox, a turning chamber and a convection part, as well as brickwork made, for example, from sheet refractory material, heat insulating materials and elastic plaster attached to the boiler bandages.

The purpose of the invention is to reduce the weight of the collectors and thereby reduce the specific metal consumption. This is achieved by the fact that in the proposed boiler the pipes of the screens are arranged horizontally in height: in the lower part of the boiler, up to the rotating chamber along the perimeter of the firebox, and higher up along the perimeter of the whole boiler. In order to provide the necessary speed of movement, the boiler is made with a variable cross section in depth.

The drawing shows the boiler, a longitudinal section.

The lower headers of the boiler 1, which are interconnected, are the supporting frame. Front vertical collectors of 2 screens and stoves 3 of the convective part of the boiler are connected to the lower collectors. To the upper ends of the collectors 2 attached front collector 4 ceiling screen. The upper collectors of 5 convective surfaces are connected to the convection part. The rear collector 6 of the ceiling screen is connected to vertical pipes supported on an unheated standpipe 7 extending from the upper collector of the left half of convective heating surfaces to the lower collector of the right half of convective surfaces. The upper collector of the right half of the convective part is connected to the lower collector of the unheated insulated pipe 8.

To the collectors, divided by internal transverse partitions into separate chambers, are attached pipes that form the screens of the boiler.

The lower bottom screen 9 and the upper ceiling screen W consist of temp pipes. Horizontal pipes are attached to the vertical front collectors, shielding vertical surfaces are thin and rotary, and the lower part of the furnace is shielded to the height of the dividing wall between the furnace and the convection chamber (to the rotating chamber) and the upper part is shielded thin and turning the camera made of pipes 12, covering the perimeter of the furnace and the turning chamber (the perimeter of the entire boiler). Convective heating surfaces consist of bundles of pipes 13 attached to the stoves of the convective part.

Thus, the skeleton of the boiler, consisting of large diameter pipes - manifolds, sinks and standpipes, is a solid spatial system and is designed to withstand the load from shields, convective surfaces and lining.

When combined with the downward discharge of the combustion products to increase the heat transfer coefficient in the convective part of the boiler, it is extended to the front.

The lining of the boiler 14 consists of a lining layer, for example, heat-resistant asbestos cement, a heat-insulating layer, for example, slag wool, and elastic plaster over the grid.

In order to prevent the brickwork from breaking down during transportation, it is tightened with bands that are attached to the lower frame of the boiler. To distribute the puffing forces under the bandages, they put slats that simultaneously fix the layers of heat insulating materials and prevent them from settling, caking and loss of heat insulating properties.

In the brickwork of the boiler there are pit windows 15 to observe the combustion process and removable insulated panels 16, in which you can inspect the convective heating surfaces.

To inspect the screen surfaces during the boiler shutdown, penetrate the burner through the embrasures into the furnace. Blast valves 17 are installed in the | Upper part of the boiler.

The specific metal consumption and the weight of the boiler are the smallest compared to other known boilers of the same performance. Due to sufficiently high speeds and the absence of water descending in the surface pipes, as well as good mixing of the heated water in the collectors, boiling of water in separate sections of the boiler and the associated water hammering and overpressure of the pipes, as well as internal corrosion of the pipes during water deaeration .

Vents to remove air from the boiler are installed on the upper headers of the ceiling screen and the upper headers of the convective part. If necessary, the scheme of water circulation in the boiler can be changed by directing cold water from the return line of the heat supply system either first to the screens and then to convective surfaces, or vice versa. -The inclusion of the convective part and between the screens. The boiler design allows you to create a series of transportable hot water boilers for the preparation of hot or superheated water from a heat producer from 1 to 15 Gcal / hour. Such boilers can be used in boiler rooms for heat supply of the building. Boilers with a capacity of from 1 to 3 Gcal / h can also be used as mobile boilers.

The boiler is fully drained and suitable for covered and half open installations. Everything

boiler maintenance is carried out from the front.

The fully assembled boiler is delivered in walled form to the installation site by rail OR on a trailer.
