Abstract: An heat absorption device based on heat recovery of oven was designed. This device united the oxygen free copper tube which had good thermal conductivity and excellent welding performance with stove bracket into a whole，it closely absorbed lost heat of the flame around the stove，and heated up the water for daily use. Improved the out-water device，made it form a recycled structure with heating device to achieve the target of protecting the whole system. The innovative device enhanced the effect of energy utilization，reduced energy consumption and achieved the goal of energy saving.

Key words: heat recovery of oven, energy-saving and emission-reduction, heat absorption device
