The briquet gas recombustion device includes a cylinder form insulated cover (1) whose inner wall is inclined to receive an exhaust tube (6) with its collector opening positioned within the gas collector room (4). The bottom side of the tube (6) has a number of minor air holes (5), and within the tube (6) there suspends a tube (7) across the tube (6) on its side walls. The tube (7) has several air chambers (10) in parallel which have a number of air pores on the side walls. The gas including CO and SO2 swirls on the obstruction of the cross tube (7) for good mixing with air to make better combusion.
