High-Temperature and High-Pressure Fluid Electric Heater Overview:

High-temperature and high-pressure fluid electric heaters, comprising a housing and a heating tube. The housing cavity is fitted with a metal tube, one end of which protrudes from the housing as the heating medium outlet, and the other end as the heating medium inlet. The heating tubes are evenly distributed along the inner diameter wall of the metal tube, with each tube tightly adhering to the inner diameter wall. The housing includes an insulation shell and an insulating layer covering the insulation shell. Consequently, this patent is capable of heating gaseous and liquid mediums under high temperature and high-pressure conditions, featuring high pressure-bearing capacity (up to IOMpa), high-temperature resistance (above 800 degrees Celsius), low cost (one-fifth of high-pressure and high-temperature boilers), rapid heating, and high efficiency.

A high-temperature and high-pressure fluid electric heater is an internationally popular, high-quality, long-life electric heating equipment. It is used for heating, temperature maintenance, and warming of flowing liquid and gaseous mediums. As the heating medium passes through the heating chamber of the electric heater under pressure, it uniformly carries away the tremendous heat generated by the electric heating elements during operation, according to the principles of fluid thermodynamics, thus achieving the temperature of the heated medium as required by the user's process.

Section 2: Working Principle of High-Temperature and High-Pressure Fluid Electric Heater:

A high-temperature and high-pressure fluid electric heater converts electrical energy into heat to heat the material requiring heating. During operation, the low-temperature fluid medium enters through the inlet under pressure, flows along a specific heat exchange channel inside the electric heating vessel, and follows a path designed based on fluid thermodynamic principles, carrying away the high-temperature heat energy generated by the electric heating elements. This raises the temperature of the heated medium, resulting in a high-temperature medium at the electric heater's outlet as required by the process. The internal control system of the electric heater automatically adjusts the output power based on the temperature sensor signal at the outlet to ensure uniform temperature of the medium. In the event of overheating of the heating elements, the independent overheat protection device of the heating elements immediately cuts off the heating power, preventing the heated material from overheating, which can cause coking, deterioration, carbonization, and in severe cases, damage to the heating elements. This effectively prolongs the service life of the electric heater.
