Boiler heating tubes are mainly categorized into stainless steel heating tubes and ceramic heating tubes. The stainless steel electric heating tube is a tubular electrical heating element composed of a metal tube, a spiral resistor wire, and magnesium oxide powder. Inside the stainless steel seamless tube, the high-temperature resistor wire is evenly distributed, while the voids are filled with magnesium oxide powder, which has excellent thermal conductivity and insulation properties. When current passes through the resistor wire, the heat is transferred through the magnesium oxide powder to the surface of the metal tube, and then the heat is further transferred to the water inside the boiler, achieving the heating purpose. The ceramic electric heating tube is made of high-quality ceramic as the matrix and high-quality electrical heating wires wound around it. It features high electrical to thermal conversion efficiency, rapid heating, low thermal inertia, high resistance to high temperatures and corrosion, good thermal-chemical stability, long service life, high insulation strength, and is non-polluting. Compared to other electric heating elements, it can save energy by about 30%.
