Embodiment

[0040] Please also refer to Figure 1 to Figure 2 , The embodiment of the present invention provides a heating furnace system 10 , which mainly includes a separator 1 , a heat exchanger 2 , an oxidation reactor 3 , a reduction reactor 4 and a heating furnace 5 .

[0041] The reduction reactor 4 includes a reduction reactor first inlet 407 for feeding fuel, and for feeding an oxidized oxygen carrier (in this embodiment, M x o y Indicates that the second inlet 408 of the reduction reactor is used to output the reduced oxygen carrier (in this embodiment, M x o y-1 Shown) the first outlet 409 of the reduction reactor and the second outlet 410 of the reduction reactor for outputting high-temperature flue gas.

[0042] At a certain temperature, the oxidized oxygen carrier releases oxygen in the reduction reactor 4 and is converted into a reduced oxygen carrier, which is output to the oxidation reactor 3 from the first outlet 409 of the reduction reactor.

[0043] The fuel enters...

Abstract

The invention provides a heating furnace system and heating furnace equipment, and belongs to the technical field of heating furnaces. The heating furnace system comprises a reduction reactor first inlet, a reduction reactor second inlet, a reduction reactor first outlet, a reduction reactor second outlet, a heating furnace first inlet, a heating furnace second inlet, a heating furnace first outlet, a heating furnace second outlet, a separator first inlet, a separator second inlet, a separator first outlet, a separator second outlet, a separator third outlet, an oxidation reactor first inlet,an oxidation reactor second inlet, an oxidation reactor first outlet, an oxidation reactor second outlet, a heat exchanger first inlet, a heat exchanger second inlet, a heat exchanger first outlet anda heat exchanger second outlet. According to the system, the problems that pollutants are generated and the heat efficiency is low in the operation process of a traditional heating furnace can be solved, so that the high-efficiency and low-emission operation of the heating furnace can be realized. The heating furnace equipment comprising the system is high in efficiency and low in operation cost.

Description

technical field [0001] The invention relates to the technical field of heating furnaces, and in particular to a heating furnace system and heating furnace equipment. Background technique [0002] At present, the heating furnace uses fuel and air contact combustion to heat the process medium, and the high-temperature flue gas is discharged through the waste heat recovery system. The operating mode of this heating furnace will generate environmental pollutants, and it is difficult to further improve the thermal efficiency, specifically the following problems. 1) The combustion of fuel in direct contact with air will produce NO x , CO 2 2) Due to the existence of low-temperature dew point corrosion, the exhaust gas temperature of the heating furnace is above 120°C, and the low-temperature waste heat of the flue gas cannot be recovered in depth, which restricts the improvement of the thermal efficiency of the heating furnace; 3) The excess air coefficient in the combustion pro...
