Calculation error of the heating furnace’s thermal efficiency
Thread Content
When conducting flue gas tests on petrochemical heating furnaces, is there any requirement regarding the fact that the heating load of the furnace should fall within a certain percentage range of the design load? Does testing at lower loads affect the results obtained from calculations related to thermal efficiency? If so, what is the reason for this? Are there any specific guidelines or data available on this topic?
When conducting flue gas tests on petrochemical heating furnaces, it is generally recommended that the heating load of the furnace should be within the range of 70%-100% of the design load. If testing is conducted at low load, the data obtained may affect the back-calculated results of thermal efficiency. This is because during low-load operation, combustion may be incomplete and the heat exchange efficiency decreases, resulting in a lower calculated thermal efficiency. Specific standards and data can be found in relevant process design manuals or petrochemical industry standards. .
Haha, it seems it’s still possible after all, haha
