Heat-conducting filler for riser heat exchanger and construction method of heat-conducting filler
The invention discloses a heat-conducting filler for a riser heat exchanger and a construction method of the heat-conducting filler, and the heat-conducting filler comprises the following components in percentage by mass: 61-64% of high-temperature-resistant silicon carbide, 19-20% of alumina powder, 6.5-7.5% of scaly high-heat-conductivity graphite powder, 5-6% of steel fiber, 4.5-5.5% of cement and 1-3% of silica sol. The silica sol accounts for 4-5.5% of the total weight of the raw materials. By adopting the heat-conducting filler for the riser heat exchanger, the heat-conducting property can be effectively improved, the heat exchange efficiency is improved by 20-30%, the steam yield of the riser heat exchanger is improved to a greater extent, and the economic benefit of a riser waste heat recovery system is improved.
本发明公开了一种上升管换热器导热填料及其施工方法，包括耐高温碳化硅、氧化铝粉、鳞片状高导热石墨粉、钢纤维、水泥、硅溶胶，其质量占比为：耐高温碳化硅61％～64％，氧化铝粉19％～20％，鳞片状高导热石墨粉6.5％～7.5％，钢纤维5％～6％，水泥4.5％～5.5％，硅溶胶占以上原料总重的4％～5.5％。采用本发明的上升管换热器导热填料可有效改善导热性能，提高换热效率20％～30％，较大程度上提高了上升管换热器的产汽量，提升上升管余热回收系统的经济效益。
