Boiler heating tubes are mainly divided 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 helical resistance wire, and crystalline magnesium oxide powder. High-temperature resistance wires are evenly distributed within the stainless steel seamless tube, with crystalline magnesium oxide powder filled in the gaps, which has good thermal conductivity and insulation properties. When current passes through the high-temperature resistance wires, the heat generated diffuses through the magnesium oxide powder to the surface of the metal tube, and then the thermal energy is 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, with high-quality electric heating wires wound around it. It has high electrical to thermal conversion efficiency, rapid heating, low thermal inertia, high resistance to high temperatures and corrosion, excellent thermal-chemical stability, long service life, high insulation strength, and is pollution-free. Compared to other electric heating elements, it can save energy by approximately 30%.
