A hot blast producing system is provided to significantly reduce costs by using waste heat bypassed from a combustion chamber as hot blast for a dryer in an industrial field. A hot blast producing system comprises a combustion chamber(10) for burning noxious gas; a plurality of thermal accumulation chambers(20) arranged in a lower portion of the combustion chamber, shield by a separation wall, and equipped with a thermal accumulation material(21); and a channel converting unit(70) for connecting a noxious gas inlet pipe(33) and a clean air outlet pipe(36) to each thermal accumulation chamber. The combustion chamber is equipped with an overheat prevention bypass pipe. The hot blast producing system further includes a hot air mixer(41) and a hot blast pipe(42). The hot air mixer is connected with a bypass recovery pipe(31) directly extracted outwardly from the combustion chamber and an exhaust branch pipe(37) branched off from the clean air outlet pipe, so that the hot air mixer mixes air of high temperature variation. The hot blast pipe is connected to the hot air mixer, and supplies mixed hot blast to a dryer(2). |
