Problems solved by technology
Heat pipe heat exchangers are widely used, with stable power and good heat transfer efficiency, but the life of heat pipe heat exchangers is seriously affected by the chemical incompatibility of molten steel. Unstable, and the service life is also significantly reduced, and a heat pipe heat exchanger can only specifically recover waste heat within a temperature range

Description
technical field [0001] The invention relates to the field of heat exchangers, in particular to gas cooling heat exchange equipment and industrial waste heat recovery equipment, in particular to a tubular ultra-high temperature gas cooler. Background technique [0002] In industrial production, a large amount of industrial gas is often produced. According to the temperature grade, industrial waste heat is generally divided into three types: high-temperature waste heat above 600°C, medium-temperature waste heat between 300-600°C and low-temperature waste heat below 300°C. Due to the increasing shortage of resources, more and more attention has been paid to energy saving and environmental protection. A variety of new energy-saving heating and combustion equipment have been gradually developed and improved, and the use of high-quality insulation materials such as new refractory fibers has significantly reduced heat dissipation losses. For the combustion equipment, the advanced c...
