By the method and the device, the problem of partial burn is solved, the continuous workability of the gasifier is guaranteed, full oxidation and material discharge are facilitated, gas temperature is reduced and afterheat is fully utilized. A fuel conveniently and reliably flows; combustion is stable; harmful gases such as the tar and the like are not discharged; and a furnace end is not blocked.

The invention belongs to a stove transforming plants, coal dust and other combustible into combustible gas to be combusted for indirect heating, and particularly relates to a heating double-layer gasifier used for cooking and heating in winter. An existing gasifier is generally limited to be used in a single home, combustible gas generated in a gasifier body is directly used for cooking and heating, the purity of the generated combustible gas is not high enough, and combustion is not powerful; and a smoking phenomenon still exists, and the health of family members is influenced. The heating double-layer gasifier comprises a gasifier body, a heat supply device, a combustion device and a gas supply device. The gasifier body is communicated with the heat supply device through heating medium space and communicated with the combustion device through a gas pipe. The gas supply device is communicated with the combustion device and the gasifier body through an air supply pipe. A burner of the combustion device is aligned to a combustion space flame inlet of the heat supply device. The heating double-layer gasifier is reasonable in design, compact in structure, convenient to use, long in fuel gasification time, high in heat efficiency, suitable for vast rural areas in short of fuel resources, wide in fuel range and low in cost.
