And valves are arranged on the organic tail gas pipe 4, the fan pipe 16 and the blowback pipe 20. A bypass adjusting valve is arranged on the hearth bypass flue 12.
Specifically, when the organic tail gas is used, when the concentration of the organic tail gas entering through the organic tail gas pipe 4 is high, the heat is released in the heat storage oxidation furnace 6 to maintain the temperature of a hearth above 800 ℃, and the use amount of heat conduction oil in the processes of fuel heating chemical industry, grease industry and the like can not be supplemented, and when the concentration of the organic tail gas is low, natural gas is supplemented through the natural gas pipe 1 in order to provide heat for the heat conduction oil, and the energy balance of the first heat storage chamber 7, the second heat storage chamber 8, the third heat storage chamber 9 and the heat conduction oil is maintained by utilizing the energy of the natural gas;
organic tail gas enters a first heat storage chamber 7, a second heat storage chamber 8 and a third heat storage chamber 9 through an organic tail gas pipe 4 at the bottom of a furnace body, exchanges heat with a heat storage body in the organic tail gas pipe, is heated to 760 ℃, then enters a heat storage oxidation furnace 6, maintains the temperature of a hearth to be more than 800 ℃ under the self-combustion heat release or gas combustion, the combusted smoke gas enters the third heat storage chamber 9 to be discharged, and the bottom of the second heat storage chamber 8 is subjected to smoke gas back blowing and has the function of blowing residues absorbed by the heat storage body after the first round of waste gas in the heat storage body;
