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. It is composed of metal tubes, spiral resistance wires and crystalline magnesium oxide powder, which are evenly distributed in the stainless steel seamless tube For high-temperature resistance wire, fill the gaps with crystalline magnesium oxide powder with good thermal conductivity and insulation properties. When current passes through the high-temperature resistance wire, the heat generated is diffused through the magnesium oxide powder to the surface of the metal tube, and the heat energy is transferred to the boiler. In the water, to achieve the purpose of heating.
The ceramic electric heating tube is made of good ceramics as the matrix and high-quality electric heating wires. It has high electric heating conversion efficiency, fast heating, low thermal inertia, high temperature resistance, corrosion resistance, good thermochemical performance stability, and service life Long, high insulation strength, no pollution, energy saving about 30% compared with other electric heating elements.
