Description

The proposed device for charging small fuel into the furnaces consists of a series of lattices inclined in different directions in the bunkers, I get: the power to transfer fuel from one grid to another, dried by combustion products, which are supplied from the chimney of the furnace through pipes to the lower part bunker. In order to eliminate shutters in the bulk of the fuel, the lower grilles are twisted larger than the upper grille, and to remove large impurities to the fuel on the underlying grilles, through the hatches in the walls of the bunker, the upper parts of the grilles are provided with hatches.

In FIG. 1 is a schematic front view of a device for loading shallow fuel into a furnace; FIG. 2 is a side view.

In bunker A, there are several obliquely mounted frames with Bf gratings, with the upper grate being made more frequently than subsequent ones in order to eliminate the possibility of internal jams of movement of finely flowing fuel, such as milled peat. The inclination is made for a greater shift of fuel to the bottom of the lattice, so that extraneous mechanical impurities accumulate in a low place of the lattice, and also so that the upper end of the lattice is exposed and gives free passage to the rising combustion products from the furnace supplied through pipes L from a special fan that makes intake of gases in front of the exhauster or pipe. In order to transfer fuel from one grid to another, the grids are driven into motion by conventional mechanisms, such as rotating eccentrics C or some other mechanical device.

The products of combustion pass through vertically falling streams of fuel in the narrow part of hopper hoses, rise through the upper end of the grate, free of fuel, and pass gradually in the same order through all the grids and all falling streams of fuel from one lattice to another. In the upper parts of the gratings, hatches P are made through which it is possible to descend down into the bunker along a special staircase and remove through the corresponding hatches in the walls of the bunker all large impurities accumulated in low places of the underlying gratings.

With the described loading and drying of finely flowing fuel, for example, milled peat, the latter is strongly dried and enters the furnace in an air-dry state, and the lumps of wet peat frozen in winter are quickly scattered into fines.

The subject matter of the invention.

Claims (4)

1. A device for loading shallow fuel into furnaces, characterized by the use in the bunker A of a series of consecutively arranged, inclined alternately in different sides of the gratings B, driven by conventional mechanisms into a progressive movement for the purpose of transferring fuel from one grid to another. 2. The form of the implementation of the adaptation of pOh, p. 1,: characterized by the use of gratings with unequal fussings: in the lower gratings, larger than in the upper grating, in order to eliminate jams 6 of the mass of fuel. 3. The form of making devices according to Claims 1 and 2, which is used in the upper parts of the manhole lattices for the purpose of accessing the underlying lattices to be removed from them, through the hatches in the walls of the bunker, unauthorized large ones bring to the fuel. 4. The use of device L in the lower part of the bunker of pipes L for supplying combustion products from the chimneys of the furnace for the purpose of drying fuel. fng1 fng l
