Abstract

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.

Description

Technical field: [0001] The invention belongs to the technical field of combustion furnaces, and in particular relates to a regenerative combustion furnace and a working method. Background technique: [0002] With the continuous advancement of economic globalization, resource and environmental issues have become increasingly prominent. As industrial furnaces are a large energy consumer, how to implement efficient and environmentally friendly energy-saving technologies as soon as possible has become a top priority. The main purpose of adopting the regenerative burner in the early stage is to further increase the preheating temperature of the air, recover the heat taken away by the flue gas to a greater extent, and save energy. However, due to high temperature combustion brings high NO X emissions, thus limiting its promotion and use in industrially developed countries. Invention content: [0003] The object of the present invention is to provide a regenerative combustion ...
