Abstract

The invention relates to a boiler waste heat recovery device, which comprises a boiler return water tank and a heat absorption tank installed on a flue. Among them, the heat absorbing tank is provided with a flue gas channel extending from the bottom of the heat absorbing tank to the top of the heat absorbing tank, a plurality of heat absorbing steel pipes are arranged inside the heat absorbing tank, and water inlets and outlets are provided on the outer wall of the heat absorbing tank. The water inlet and the water outlet are respectively connected to the boiler return water tank through pipes. The invention realizes secondary recovery and reuse of boiler waste heat, greatly increases boiler inlet water temperature, achieves the goals of coal saving, energy saving and environmental protection, and reduces cost while improving boiler thermal efficiency.
