The invention discloses a circulating gas heating furnace combustion system which comprises at least two circulating heating furnaces; each of the circulating heating furnaces is provided with a heatstoring body, a replaced gas outlet, a circulating low temperature gas inlet, a circulating high temperature gas outlet, a furnace smoke discharging outlet and a replacing gas inlet; a gas burner capable of generating heat through combustion to enable the heat storing body to store heat is arranged on each of the circulating heating furnaces and is provided with a combustion air inlet and a gas inlet; for the at least two circulating heating furnaces, at least one carries out the heat storing procedure, and at least one carries out the heat releasing procedure; the circulating heating furnaceafter finishing the heat releasing procedure utilizes the flue gas discharged by the circulating heating furnace carrying out the heat storing procedure to purge the residual gas and then the procedures of the at least two circulating heating furnaces are switched. According to the circulating gas heating furnace combustion system, after finishing the heat releasing procedure, the flue gas is utilized to purge residual gas in the circulating heating furnaces to replace the residual gas, the heat storing procedure is then switched to, and the safety problem that gas is left in equipment to cause combustion and explosion is solved.
Description
technical field [0001] The invention relates to the technical field of circulating gas heating, in particular to a combustion system of a circulating gas heating furnace. Background technique [0002] In the oil shale dry distillation process, the main heat supply equipment is a regenerative heating furnace that works intermittently, which is used to circulate and heat the gas. It usually consists of three regenerative heating furnaces, which are used alternately periodically. When the heating furnace releases heat, the low-temperature gas from the circulating low-temperature gas preparation workshop enters the heating furnace, becomes high-temperature gas after being heated by the regenerator in the furnace, and then enters the carbonization workshop to participate in other processes. [0003] After the heating furnace has released the heat, there is a large amount of gas remaining in the furnace. When the heating furnace switches from the exothermic state to the heat stor...
