Boiler heating tubes are mainly categorized into stainless steel heating tubes and ceramic heating tubes. The stainless steel electric heating tube is a tubular electric heating element, composed of a metal tube, a spiral-shaped resistance wire, and crystalline magnesium oxide powder. The high-temperature resistance wire is uniformly distributed inside the stainless steel seamless tube, with the crystalline magnesium oxide powder, which has good thermal conductivity and insulation properties, filling the gaps. When current passes through the high-temperature resistance wire, the heat is diffused through the magnesium oxide powder to the surface of the metal tube. The heat is then transferred to the water inside the boiler, achieving the heating purpose. Ceramic electric heating tubes are made of high-quality ceramic as the matrix and are wound with high-quality electric heating wires, offering high electric heat conversion efficiency, rapid heating, low thermal inertia, high-temperature resistance, corrosion resistance, good thermal-chemical property stability, long service life, high insulation strength, and are pollution-free. Compared to other electric heating elements, they can save energy by about 30%.
