    The invention relates to a method and apparatus for the combustion of large solid fuels. In order to improve the beneficial effect of sound on combustion, a bed of the fuel (131, located on a grate (12), is exposed to the high particle velocity of a sound positively produced by an external low frequency sound generator (25, 20), the frequency of which is determined by the sound generator, to provide a reciprocating movement of combustion air and combustion gas through the fuel bed. The dimensions of the grate in a plane transverse to the reciprocating movement of the combustion air and the combustion gas are less than a quarter of the wave length of the sound generated by the sound generator.

    The aim of the invention is to increase the combustion efficiency.
    Figure 1 shows a device that implements the proposed method, with a quarter-wave resonator, a cross-section; figure 2 - device with a combustion chamber, a cross-section; FIG. 3 shows a device with a resonator placed above the grating; 4 shows a device with a passive resonator under the grating; Fig. 5 shows a device with positive feedback; FIG. 6 shows a device with a half-wave resonator; 7 shows a device with a three-quarter wave resonator; FIG. 3 shows a device with external communications.
    The device contains a grating 1, on which a layer 2 of fuel is placed, a resonator 3 having a low-frequency sound generator 4, as well as an air supply nozzle 5. In embodiments, the device is equipped with a combustion chamber 6 with a charging neck 7, an exhaust nozzle 8 and a passive resonator 9. In In one embodiment, the device comprises a bellows 10, adjustable by a signal from a pressure sensor 11 installed in a passive resonator 9. The latter may have an extension 12 with a collection of 13 solid particles. In the embodiment (FIG. 3) with external communications, the generator 4 is connected by pipe 14 to the blower 15. The exhaust pipe 8 is equipped with cooling shirts 16 and 17, a smoke exhauster 18 and a pipe 19.

    Example. Burning layer 2., Fuel located on grid 1 is affected by acoustic oscillations with a frequency below 60 Hz from a low-frequency sound generator 4 through resonator 3, Air is fed through an air inlet 5, During operation of the device with a passive resonator 9, through which the combustion products, solid particles are collected in the expansion 12 and are removed in the collection 13. When the device operates with positive feedback, the pressure sensor 11 provides the frequency of the generator 4, equal to the frequency of the first harmonic of the resonator 3
