Description

The shaft furnaces of low and medium capacity for the combustion of milled peat and wet coal are known. They are made in the form of a remote brick chamber with an air or steam fuel spreader, which partially burns the aircraft, and partly on the grid. However, in these toiks, it is impossible to burn high-moisture fuel with a high content of fines due to insufficient slipping.

In the proposed shaft furnace, this is eliminated by an interactive sucker of fuel with hot flue gases inside the shaft, for which it is equipped with partitions that form vertical channels-diffusers, which, with an intense 1 drying inside the shaft, are warm with high humidity. They are equipped with air or air heaters for suction from the furnace of high-temperature gases.

On . 1 shows a longitudinal vertical section and: an achy firebox; on fng. 2- ps; a thin peppermint shaft section along line AA in FIG. one; FIG. 3 is a horizontal section of thin lines but BB and BB of FIG. one.

The firebox is made in the form of a detachable brick chamber with a shaft / formed by two vertical brick walls 2 and 3. The shaft mines / are located partitions 4, forming the vertical channels 5, and the shape of the diffusers. The upper and lower parts of the shaft are connected by a firing chamber with 6 windows. Through the upper window 7 into the shaft / for fuel drying, hot flue gases are ignited, and through the lower window 8, fuel is fed into the combustion chamber 6 d, 1 of combustion.

Fuel from the hopper 9 with the help of feeder 0 is fed into the mine /, where it is dried with hot thin gases entering the diffusers 5 through the upper window 7. The fuel dried in the diffusers 5 first gets to the inclined plane // and then to the horizontal table} 2 located at the bottom of the shaft directly in front of the nozzles of the spreader 3, embedded in the frontal wall of the thin. From the table} 2 the fuel is blown into the chamber 6 by air or steam.

When the fuel is supplied, the spreader 13 simultaneously performs its sorting and sorting. The largest pieces lie in the immediate vicinity of the front step, then there are pieces of smaller size, the fines burn in a weighted state.

Subject and scr

The firebox of the boilers of small and medium combustion of milled peat and fines is a detachable brick chamber, which has a fuel spreader and in which the latter is partially on the grid, such as the towns that form vertically the 1st channels of the purpose of drying inside nostyo mines, equipped with air or steam furnaces of high-heated gases.
