Boiler device

The utility model discloses a boiler device. The boiler device comprises a first boiler, a second boiler and a pulverized coal discharging tube (6), wherein the first boiler is provided with a first pulverized coal bunker (1); the second boiler is provided with a second combustor (13); when the first boiler stops running, the pulverized coal discharging tube (6) is connected between a coal outlet of the first pulverized coal bunker (1) and the second combustor (13); and the coal outlet of the first pulverized coal bunker (1) is connected with the second combustor (13), so that pulverized coal in the first pulverized coal bunker (1) is discharged into the second combustor (13). By the boiler device, residual pulverized coal in the pulverized coal bunker of the boiler which stops running can be thoroughly discharged rapidly; the safety of the boiler device is guaranteed; and moreover, because the discharged pulverized coal is directly discharged into the running second boiler and is combusted, the pulverized coal is prevented from being wasted, and the economic benefit is improved.
