The invention discloses a dual-fuel energy-saving hot-blast stove, and relates to the technical field of stove type heating equipment. The dual-fuel energy-saving hot-blast stove is composed of a stove body and a combustor, wherein the stove body is of a hollow cavity structure; an air inlet is formed in the head part of the stove body; an air outlet is formed in the tail part of the stove body; the air inlet is equipped with the combustor; and the stove body is formed by connecting a combustion part, a harmless part and an air distribution part end to end. The hot-blast stove disclosed by theinvention is good in temperature-control effect, avoids generation of dioxin, and facilities environment-friendly emission of gas. The stove body is formed by connecting the combustion part, the harmless part and the air distribution part end to end, the combustion part is used for combusting and heating up, the harmless part is used for controlling temperature to inhibit generation of dioxin, and the air distribution part is used for regulating the temperature of outlet gas. The dual-fuel energy-saving hot-blast stove can utilize non-condensable gas to support combustion for the hot-blast stove, is additionally equipped with an air distribution pipeline for supporting combustion and regulating concentration of non-condensable gas, and air distribution and temperature regulation in an outlet tank direction; and combustion-supporting air pre-heating channels have air pre-heating functions, so that heat energy does not need to consume during combustion support, and therefore, the energy-saving effect is achieved.
