SU905A1 - Shaft type firebox with stepped grating and rotating grate drum - Google Patents

Description

Well-known mine - chain furnaces, with all their good qualities, have, however, some weaknesses, for example: the failure of fine fuel through the grates, the impossibility | when working with a blast airliner, it is necessary to direct and distribute it in its image, the complexity and high cost of the device:

The proposed combination of the shaft i furnace with a drum of a special device and the aim is to eliminate the above-mentioned shortcomings.j

The drawing shows a firebox in 2 longitudinal sections along the line A A and B B.

lia stationary shaft 1 slowly turns; a grate drum consisting of an axial tube 2 with ribs L, to which solid radial partitions are riveted, dividing the drum into separate chambers; each chamber is provided with a frame 7, riveted both to the solid side walls J of the drum and to the radial partitions, which are also attached to iiOMoau 0 6 squares with walls 5. The drum receives rotation from the tail wheel -I On frame 7 lie

perforated grates iS. having ribs 9 with holes through which the rod 1 passes (holding the tiles 8 from falling and secured with nuts or wedges..

Air enters the grate drum through fixedly fixed on the shaft / pipe 11, provided with openings, from the part that is under the drum chamber with the fuel-loaded tile and 6. The amount of IT3 supplied bore pipe. // Air into each chamber can be adjusted using a gate that is located at each outlet of the pipe. The tiles 8 are provided with fingers 7.7, which, like the tiles themselves, can be replaced; fingers /.V serve for scrapping of sclabs and ashes from the image. For cleansing plitsms; S from slag adhesion you have ;: scraper / 4; The slag and ash, when refined, in both cases fall into the trolley 12.

According to the author, the action of the firebox is as follows: the fuel from the mine, where it, with the help of slots in its walls, visible in the drawing, is hooked up. falls on a slant with his

especially with ash-field and with a small access of air, partly it, raya 3 (.). Further, the fuel is pushed onto the drum, where, under the influence of a strong air flow (or blowing), it finally burns as it approaches the gap between the baroejiom and the prepared wall. The bout of the vessel and CO are burned in the furnace space in the presence of excess air, which is very hot when passing through the heated layer of 11L1 vacuum on the drum. If necessary, you can give an additional air flow into the combustion space.

The action of the firebox can be regulated both by changing the speed of rotation of the drum using stepped pulleys (or gearboxes) and the amount of air supplied to the drum and to the separate ash pit of the inclined grate.

The grate perforated tiles, being washed by a strong inflow of air, do not heat up, but the flow is H1lak

it does not stick and is easily detached, which is achieved more easily. The service of the grate tiles

Subject of the patent.

A shaft-type firebox with a stepped grating and a rotating grate drum, which is characterized with eHeHJteiM in the said drum, is connected; the drum wall side 10, what the drum is equipped with an axial tube 2 with an opening and in its cylindrical wall opening into the cavity of each of the chambers and serving to feed them through the same holes Bristles in the blast pipe 11, located only on the part of its circumference, which corresponds to the chambers of the drum, which are loaded; on

their grid-iron tiles TOP BOM.
