However, their operational safety, especially during sudden power outages, is often overlooked. An unexpected power failure, if not handled properly, can lead to severe fires or even explosions within minutes. This article analyzes causes and prevention of fires in Electric Thermal Oil Heaters During Power outages.<\/p>\n\n\n\n

1. Why Do Power Outages Cause Fires? Key Reasons<\/strong><\/h2>\n\n\n\n

A common misconception is that when the power goes out, the electric heater stops working, and the system becomes safe. In reality, the danger lies in the stagnation of high-temperature thermal oil<\/strong>. Here are the main reasons:<\/p>\n\n\n\n

    \n
  1. Circulation Pump Stops, Causing Oil Stagnation<\/strong>
    When the power fails, the circulation pump stops immediately. Although the electric heater shuts off, the heating elements and pipeline walls remain extremely hot (often above 300\u00b0C). The stagnant oil continues to absorb heat, leading to localized overheating.
    Result:<\/strong>\u00a0The thermal oil cracks and carbonizes, forming coke deposits. These deposits reduce heat transfer, creating a vicious cycle of more overheating and coke formation. Eventually, the pipeline may weaken, deform, or rupture.<\/li>\n\n\n\n
  2. Thermal Oil Decomposes Rapidly When Overheated<\/strong>
    Thermal oil is an organic substance with limited thermal stability. Localized overheating causes it to break down, generating flammable gases and low-boiling-point compounds. These gases have low explosion limits and can ignite easily.
    Result:<\/strong>\u00a0The decomposed gases increase system pressure, potentially exceeding the expansion tank\u2019s capacity. This may cause leaks or trigger safety valve releases.<\/li>\n\n\n\n
  3. Air Enters the System, Forming Explosive Mixtures<\/strong>
    During a power outage, temperature changes or leaks can create negative pressure, sucking air (oxygen) into the system through seals, flanges, or the expansion tank.
    Result:<\/strong>\u00a0The high-temperature oil (and flammable gases) mixes with oxygen, forming an explosive mixture. When the power returns or another ignition source is present, combustion or explosion may occur.<\/li>\n\n\n\n
  4. Improper Emergency Response<\/strong>
    If operators panic and fail to follow procedures\u2014such as shutting off the heater, activating emergency cooling, or venting the system\u2014the situation can quickly escalate.<\/li>\n<\/ol>\n\n\n\n

    2. Prevention Methods: How to Avoid Fires<\/strong><\/h2>\n\n\n\n

    Prevention is always better than mitigation. To avoid fires during power outages, implement the following measures:<\/p>\n\n\n\n
