How to perform cold oil replacement in a heat transfer oil furnace?

How to perform cold oil replacement in a heat transfer oil furnace during a power outage? Is it necessary to have a backup generator to power the circulation pump in order to carry out cold oil replacement? Is cold oil transfer simply putting the oil from the high-level tank into the low-level tank? I’m a beginner and really don’t understand how to carry out cold oil replacement. I hope teachers and those with more experience can provide detailed explanations! Which valve should be opened first and which one second? What are the specific detailed steps for operating it? It would be great if a diagram could be drawn to show the flow path! I once again express my gratitude
Is it mainly to replace the heat transfer oil inside the furnace? Doesn’t the heating of the equipment and the heat transfer oil in the pipes need to be replaced?
Please refer in detail to the \"Instruction Manual for Heat Carrier Boilers\" provided by the manufacturer, or consult the operating procedures for heat transfer oil boilers. Of course, it is also necessary to take into account the process flow diagrams provided by the manufacturer as well as the actual conditions on site
There’s nothing yet; it’s still in the construction phase
Is it necessary to open the vent valve on the expansion tank during cold oil replacement?
Add an emergency pump so that the oil furnace can circulate
Make sure to check the liquid level in the relevant storage tanks and drain the water in advance. Raise the temperature according to the heating curve
Cold oil replacement is generally applied to heat transfer oil furnaces that use coal or other solid fuels, as the fuel in the furnace continues to burn for some time after a power outage. To protect the furnace tubes and prevent the heat transfer oil from overheating, a cold oil replacement pipeline connected to a low-level oil storage tank is usually installed on the outlet pipe of the heat transfer oil furnace. When this pipeline is activated, the low-temperature heat transfer oil stored in the expansion tank flows automatically into the furnace due to the pressure difference, passing through the expansion tube, as well as the inlet and outlet pipes of the heat transfer oil pump, before entering the oil storage tank via the cold oil replacement pipe. For fuel and gas boilers, it is generally not necessary to install cold oil replacement pipelines, as the supply of fuel stops immediately in the event of a power outage. Without a continuous combustion process in the furnace, the temperature drops rapidly as well; therefore, such pipelines serve little purpose.
Thank you for your detailed explanation! We use a 15t gas-fired heat transfer oil furnace! But right now we are still in the stage of building with traditional materials; we don’t have any equipment or supplies yet, so I’m reaching out to the seniors here for advice
May I add you on WeChat? If I have any questions in the future regarding heat transfer oil furnaces, I would like to ask you for more guidance! My WeChat ID is dc1503290
