Energy-saving monitoring is the general term for activities such as entrusting energy-saving monitoring agencies to supervise and test the status of energy utilization and to propose solutions to energy-wasting behaviors in accordance with relevant national regulations and technical standards during the process of implementing energy-saving supervision according to law. An important part of energy-saving monitoring work is to test the energy utilization status of energy-consuming equipment with infrared cameras online.

1. IR thermography camera is applied to heating furnace monitoring


Furnace and Boiler Energy Saving Monitoring The traditional heating furnace and boiler heat loss detection method is to use a point thermometer or heat flow meter for testing:

Method 1: Select some parts on the outer wall of the furnace, use a temperature measuring instrument to make the temperature measuring probe touch the part to be measured, measure the temperature value, and then calculate the heat dissipation.

Method 2: Select some parts on the outer wall of the furnace, use a heat flow meter to measure, attach its probe to the surface of the equipment to be tested, read the heat flow directly, and then calculate the heat dissipation in this area. The above two methods need to be in direct contact with the measured object, and the operator is within 1 meter from the measured object, which has the following adverse effects on the measurement accuracy: direct contact measurement destroys the temperature field of the measured object; The distance between the measured object is small, which affects the flow field of the measured object and its convective heat transfer intensity, so the error in calculating the average wall temperature and heat loss is large.

In addition, point thermometers and heat flow meters are point-type detection. For some large-scale equipment, high-temperature points may be missed, and it is difficult to detect certain high-level and difficult-to-reach parts. Online thermal imaging camera measurement is a non-contact measurement within a certain distance, which can completely avoid the above-mentioned adverse effects. The entire furnace body can be quickly scanned by using the IR thermography camera, and the image is stored in the memory card of the fuselage, and then analyzed by professional software. In this way, the temperature field distribution of the furnace body can be obtained, providing data support for the calculation of heat dissipation loss, and it is also possible to intuitively find insulation defect parts to avoid missed inspections. In addition, some special types of thermal imagers can also detect whether the furnace tube in the heating furnace is scaled or thinned due to wear through the flame and flue gas without stopping the furnace, which contributes to the energy saving, high efficiency and safety of the heating furnace. Operation provides a scientific basis. In short, the IR thermography camera is applied to the monitoring of the heating furnace, regardless of fault diagnosis, maintenance, or technical transformation, it can provide rigorous data support.

Pipeline energy-saving monitoring The hot logistics pipelines used by enterprises to transport steam, raw materials or products are usually wrapped with thermal insulation materials to reduce the loss of effective heat to the environment. As the running time increases, some parts of the pipeline insulation layer will age and fail. However, most of the above-mentioned pipelines are laid overhead, and the conventional inspection method is inconvenient to operate; it is difficult to find the heat insulation failure parts of the long-distance pipelines in time. With the use of infrared thermal imaging cameras, the entire pipeline can be quickly inspected to avoid omissions. In addition, if the pipeline is scaled or the pipeline is thinned due to wear and tear, the thermal conductivity of the part due to scaling or thinning will be significantly reduced or increased. The thermal imager can also detect this difference and give a timely warning to avoid energy waste and accidents. 

Many key equipment in industrial enterprises operate in a relatively high temperature range, and whether their operating conditions are good and economical are directly related to thermal insulation performance. Insulation failure will increase the heat dissipation loss of the equipment, increase energy consumption, push up product costs, and even cause equipment damage and even stop the entire production line. The start and stop of the device will cause a great waste of energy. Therefore, ensuring the long-term operation of the device is also an important measure for energy saving and consumption reduction. Online infrared cameras are used in energy-saving monitoring work, which can comprehensively, accurately and efficiently evaluate the energy-saving of related equipment, especially making it possible to comprehensively evaluate the insulation status of large-scale equipment. IR thermography cameras can also provide early warning of equipment failures in a timely manner, providing technical support for the safety, energy-saving, high-efficiency, and long-term operation of industrial equipment.
