Accident prone and preventive measures for electric heaters installed on thermal oil pry

Due to improper operation or management, the quality of heat transfer oil deteriorates prematurely, which is one of the common problems in the installation of electric heaters with heat transfer oil. Some heat transfer oils only take one or two years, and their performance indicators seriously deteriorate. When low-quality heat transfer oil is operated for a long time, the carbon deposition on the heating surface tube wall continuously increases, the pipe diameter decreases, the heat transfer oil flow rate continuously decreases, the resistance of the circulating pump gradually increases, and the heat transfer efficiency continues to decrease, leading to coking and blockage inside the furnace tube, which in turn causes coking and blockage inside the furnace tube, leading to explosion.

One of the reasons for the decline in the quality of heat transfer oil is the local overheating, thermal cracking, and oxidation of heat transfer oil in the electric heater installed on the heat transfer oil pry. If the heat transfer oil exceeds its specified operating temperature, it will cause local overheating, thermal decomposition and condensation, precipitation of residual carbon, decrease flash point, darken color, increase viscosity, decrease heat transfer efficiency, and cause coking and aging. The oxidation reaction between heat conduction oil and oxygen in the air generates organic acids, which condense into cement and increase viscosity. This not only reduces the service life of the medium, but also causes the failure of the system's acid corrosion control system and hidden dangers of safety protection.

What should be noted when using a single head electric heater

When a single head tube electric heater is used to heat substances such as nitrates, paraffin, asphalt, etc. that are prone to melting metals or solids, the heating substance should be melted first to reduce the external voltage of the single head tube electric heater, and then restored to the rated voltage after melting. In addition, when heating substances such as nitrates that are prone to explosion accidents with a single head electric heater, safety measures should be fully considered.

When using single head tube electric heaters for air heating, attention should be paid to the uniform arrangement of single head tube electric heaters. The benefit of doing this is to ensure that the single head tube electric heater has sufficient and uniform heat dissipation space, ensure air flow as much as possible, and improve the heating efficiency of the single head tube electric heater.

Magnesium oxide is filled in the gap inside the single head tube electric heater, and the magnesium oxide sand at the outlet of the single head tube electric heater is prone to contamination due to the infiltration of impurities and moisture. Therefore, during operation, attention should be paid to the status of the output terminal of the single head tube electric heater to avoid leakage accidents.

The storage location of the single head tube electric heater must be kept dry and have appropriate insulation resistance. If it is found that the insulation resistance of the storage environment of the single head tube electric heater is too low, it can be restored by low-voltage electrification before use. Before use, the single head electric heater should be properly fixed, and the wiring part should be placed outside the insulation layer to avoid contact with corrosive, explosive media, and water.

When using a single head tube electric heater for heating liquids or metal solids, it is important to ensure that the single head tube electric heater is completely placed inside the heated object, and it is not allowed to experience empty burning of the single head tube electric heater. If there is scale or carbon on the outer metal shell of the single head tube electric heater after use, it should be removed in a timely manner to avoid affecting the heat dissipation performance and service life of the single head tube electric heater.
