Large-flow combustion device with coil pipe type mixer and barrel type fire distributor

The invention discloses a high-flow combustion device with a coil pipe type mixer and a barrel type fire distributor. Comprising an upper shell, a lower shell, an ignition device, a barrel type fire distributor and a coil type gas channel, wherein the lower shell is combined with the upper shell in an up-down structure sealing manner; the ignition device penetrates through the upper shell and the lower shell; the barrel type fire distributor is arranged in the upper shell; compared with the prior art, the large-drift-diameter gas channel reduces circulation resistance, and the attenuation coefficient is lower when an air blower conveys air volume and air pressure to the fire distributor for use; the adverse effect of condensate water on the kindling structure is reduced to the maximum extent; the occurrence of backfire safety accidents is effectively avoided, and the rated heat flow of the combustor is greatly improved; the adaptability problem of matched installation and use of the ultra-large flow premixing
