The invention relates to a high-wind-temperature hot blast heater with an automatic air preheater, which can effectively solve the problems of combustion-supporting air preheating, coal gas and air mixing, insufficient combustion, low wind temperature, complex equipment configuration and high energy consumption. The structure of the high-wind-temperature hot blast heater with an automatic air preheater is as follows: the inner circumference of the wall of a combustor is provided with coal gas nozzles and air nozzles in a staggered mode, and communicated with a premixing annular channel; the upper part in the wall of the annular combustor is provided with a coal gas distribution annular channel, and the outer wall surface is provided with a coal gas intake pipe; a combustion-supporting air preheater is arranged in the large wall of a heat accumulation chamber, the upper part is arranged in the wall of the combustor and enters the premixing annular channel through the nozzles, the lower part is communicated with a combustion-supporting air distribution annular channel in the wall of the heat accumulation chamber, and the outer wall surface is provided with a combustion-supporting air intake pipe; a cold wind chamber is arranged under the heat accumulation chamber, and the wall of the cold wind chamber is provided with a fume discharge pipe and a cold wind intake pipe; and a heat accumulator in the heat accumulation chamber is arranged on a grate which is fixed on a rigid base of the hot blast heater. The invention has the advantages of investment saving, high efficiency, energy saving, environmental protection and long service life.
