To accurately evaluate the actual energy-saving value of the Equipment Insulation jackets, this test adopts the "before-and-after comparison method": Under the premise that the equipment operating conditions (working temperature, load, ambient temperature) are fully consistent, professional instruments such as high-precision temperature sensors, heat flux meters, and power meters are utilized to monitor the equipment surface temperature and heat dissipation loss respectively before and after the installation of insulation jackets. Taking on-site images as an example: In this test scenario, when the equipment valves were not equipped with insulation jackets, their high-temperature surfaces continuously dissipated heat outward, resulting in an operating temperature of up to 120℃-200℃. After the insulation jackets were installed, heat energy dissipation was effectively blocked, and the ambient temperature around the equipment was directly reduced to approximately 35℃-45℃. —— After installing insulation jackets on the equipment pipelines and valves in the refining workshop, the temperature was significantly lowered to around 40℃, successfully meeting the standard operating temperature requirements for the equipment. The insulation measures have achieved remarkable results, effectively ensuring the stable operation of the equipment.?
