How Long Is The Service Life Of Electric Heating Tube?


The electric heating tube is the core component of electric heating. It indirectly determines the service life of the steam boiler. Can you choose non-metal electric heating tubes (such as ceramic electric heating tubes)? As it is load-resistant and has a long life, and it is a separate structure of hydropower, The steam boiler never discharges electricity. The reason is that electric heating uses a metal tubular electric heater to heat the water to indirectly convert electrical energy into thermal energy (generating hot water or steam).

There is no need to adopt the method of extinguishing to convert chemical energy into heat energy, so there is no need to provide the atmosphere and fuel required for extinguishing, no harmless gas and ash will be emitted, and it fully meets the environmental protection requirements. Classification of electric heating Electric heating can be divided into KS-D electric heating boiling water boiler, CLDR (CWDR) electric heating hot water boiler, LDR (WDR) electric heating steam boiler, etc. according to the function. The electric heating tube of the pot should be positioned and flowed. The useful fever area must be fully immersed in the liquid or metal solid. Empty burning is strictly prohibited. When the appearance of the pipe body has scale or carbonization, it should be cut off and cleaned in real time before use, so as not to affect the heat dissipation and shrink the application life.

When heating fusible metal or solid nitrate, alkali, bitumen, paraffin, etc., the electric heating pressure should be lowered first. After the medium melts, the capacity will rise to the rated electric heating pressure. When heating the atmosphere, the components should be evenly arranged, so that the components have excellent heat dissipation premises, and the flowing atmosphere can be heated sufficiently. When heating nitrate, safety measures should be taken into consideration to prevent the explosion from becoming chaotic. The wiring department should be placed in the insulation layer to prevent the corrosive, explosive medium, and moisture from fighting; the lead wire should be able to withstand the temperature and heating load of the wiring department for a long time, and the wiring screws should be guarded against excessive force. The component should be stored in a dry place. If the insulation heating resistance is less than 1MΩ for a long time, whether it is dry outside the oven circulated at 200 ℃, or reduce the electric heating pressure to pass through the explosion-proof electric heating heater until the insulation electric heating resistance is restored. The magnesium oxide powder in the outlet of the electric heating heat pipe is being used in the application to prevent the penetration of water by the pollutants and prevent the occurrence of chaotic electric heating. The electric heating is mainly composed of the boiler body and the electric control box and the control system. Its characteristics are environmental protection, clean, pollution-free, noise-free, and fully automatic. With the elimination of infinite energy, prices have fallen sharply. As an emerging steam boiler facility, electric heating has been increasingly recognized by everyone.
