The invention belongs to the technical field of
combustion furnaces and provides a thermal
storage type combustion furnace and a working method. The thermal
storage type combustion furnace comprises a combustion furnace body and two symmetrical thermal storage chambers. Each thermal storage chamber is provided with a
fuel gas pipe with a switch valve. The thermal storage chambers are connected with the combustion furnace body through burners. One thermal storage chamber is connected with a gas inlet
pipe B, and the other end of the gas inlet
pipe B is connected with a
reversing valve. The other thermal storage chamber is connected with a
smoke exhaust pipe A, and the other end of the
smoke exhaust pipe A is connected with the
reversing valve. The
reversing valve is further connected with a gas inlet pipe A and a
smoke exhaust pipe B. A video collector is arranged in the reversing valve. A
hearth pressure
detector and a smoke temperature
detector are further arranged on the smoke exhaust pipe A. The
hearth pressure
detector, the smoke temperature detector and the video collector are all connected with a
signal processor. The
signal processor is connected with a
programmable logic controller (PLC). The PLC is connected with a thick film
transistor (TFT) and an
alarm device, and meanwhile the PLC controls reversing of the reversing valve. The thermal
storage type combustion furnace and the working method have the following beneficial effects that 1, energy is saved; 2, the
furnace temperature uniformity is improved; 3, the
heat transfer efficiency is improved; 4, the concentration of
NOx is reduced; and 5, the structural design is reasonable, and the conception is ingenious and novel.
