Abstract

The invention discloses a self-preheating burner tube bundle type heat exchange tube, a self-preheating burner and a heat exchange method for improving the heat exchange efficiency of the self-preheating burner. The self-heating burner tube bundle type heat exchange tube comprises an outer tube and an inner tube, wherein one end of the inner tube extends out of the outer tube, and the other end extends into the outer tube; the inner tube consists of an inner tube orifice, an inner tube wall and an outer tube orifice; the inner tube orifice of the inner tube is positioned in the outer tube; theouter tube consists of an outer tube bottom, an outer tube wall and an outer tube orifice; a gap is formed between the inner tube orifice of the inner tube and the tube bottom of the outer tube; anda fluid running channel is enclosed between the inner tube and the outer tube. Through the adoption of the tube bundle type heat exchange tube, the heat exchange area of flue gas and combustion-supporting air is increased, and efficient heat recovery is realized.

Description

technical field [0001] The invention relates to a self-preheating burner tube bundle heat exchange tube, a self-preheating burner and a heat exchange method for improving the heat exchange efficiency of the self-preheating burner. Background technique [0002] Natural gas is a non-renewable and clean energy. With the acceleration of human industrialization, the demand for natural gas is increasing. How to improve the thermal energy utilization efficiency of natural gas has become an urgent issue. In the field of open flame heating, the traditional finned self-preheating burner has limited heat exchange area and limited heat recovery capacity, especially in low-temperature furnaces. Due to the low furnace temperature, it is more difficult for the traditional self-preheating burner to achieve high efficiency. heat recovery. [0003] The above-mentioned background technology is for the convenience of understanding the present invention, and is not a known technology that has b...
