Quartz heating tube and stainless steel heating tube are heated by forced convection to heat the fluid. The material is stainless steel, that is, the fluid is pumped into the heating chamber with a pump at one end of the heater. After being heated, it flows out at the other end of the heater. It is a heating method that is forced to circulate through the pump. Compared with the traditional heating method, it saves energy. Remarkable, scientific in technology, easy to install and use, and have obvious economic benefits.
Quartz heating tube and metal stainless steel heating tube have their own advantages and are suitable for different environmental occasions. The comparison this time is only a comparison with a certain aspect and a relative environment, in order to be able to more clearly analyze which environment to choose which heating tube to work in is the best.
Features of Quartz Heating Tube:
1. No need for far-infrared coating, good spectral radiation matching absorption characteristics, long-term use of radiation performance does not degrade, and high electrothermal conversion efficiency. Compared with general heating elements, energy saving is about 30%.
2. High working temperature and wide selection range. Among them, the ceramic cap package type has a maximum temperature resistance of 800°C.
3. Fast heating, low thermal inertia, high temperature resistance, corrosion resistance, good thermochemical stability, long service life, and high insulation strength.
4. Pollution-free, it is a clean heater, which meets the high-tempo and high-quality requirements of modern production, and is suitable for household appliances with high hygiene requirements.
5. The design, manufacture and installation are very convenient, economical and safe.
Features of metal stainless steel heating tube:
1. Small size and large power: The electric heater mainly uses clustered tubular heating elements inside, and the maximum power of each clustered tubular heating element is 5000KW.
2. Fast thermal response, high temperature control accuracy, and high comprehensive thermal efficiency.
3. Wide application range and strong adaptability: The circulating heater can be used in explosion-proof or ordinary occasions. Its explosion-proof grade can reach B and C grades, and its pressure resistance can reach 20Mpa. And the cylinder can be installed vertically or horizontally according to user needs.
4. High heating temperature: The maximum working temperature of the heater is designed to reach 850℃, which is unavailable for general heat exchangers.
5. Fully automatic control: Through the design of the heater circuit, automatic control of parameters such as outlet temperature, pressure, and flow can be easily realized, and it can be networked with a computer to realize man-machine dialogue.
6. Long life and high reliability: The heater is made of special electric heating materials, and the design power load is reasonable. The heater adopts multiple protections, which greatly increases the safety and life of the heater.
7. The stainless steel heating tube uses a metal tube as the shell, and the spiral electric heating alloy wire (nickel-chromium, iron-chromium alloy) is uniformly distributed along the central axis of the tube. The gap is filled and compacted with magnesia sand with good insulation and thermal conductivity. Sealed with silica gel or ceramic, this metal-clad electric heating element can heat air, metal molds and various liquids. The high temperature electric furnace wire is evenly distributed in the high temperature resistant stainless steel seamless tube, and the gap is densely filled with crystalline magnesium oxide powder with good thermal conductivity and insulation performance. This structure is not only advanced, high thermal efficiency, but also generates uniform heat. When there is an electric current in the wire, the heat generated is diffused to the surface of the metal pipe through the crystalline magnesium oxide powder, and then transferred to the heated part or the air to achieve the purpose of heating.
Through the comparison and analysis of the characteristics of the quartz heating tube and the metal stainless steel heating tube above, it can be seen that in a certain environment, it can be seen that:
1. Metal stainless steel heating pipes are generally resistant to dry burning and have a longer service life than quartz heating pipes;
2. The quartz heating tube should be avoided in the occasion of mechanical external force and stress, because it is brittle and fragile;
3. Quartz heating tube saves more than 15% energy than metal tube, especially carbon fiber heating tube in quartz heating, energy saving can reach 30%.
4. The metal electric heating tube can be bent to a certain extent after being formed, but the quartz tube obviously cannot;
5. The advantage of quartz heating tube is that it heats up quickly, but the temperature is also faster. It is suitable for baking food (the disadvantage is that it is not easy to clean up than metal electric heating tubes); stainless steel electric heating tube heats up slowly, but it has good insulation effect and is suitable Used in ovens that require slow heating, such as metal heat treatment;
6. Quartz tube has no advantage in heating water and solution;
7. The quartz electric heating tube is environmentally friendly, pollution-free, and avoids the generation of electromagnetic fields.
