【Help】How do fluctuations in the pressure of the fuel gas pipeline affect the furnace temperature?
Thread Content
In practical operation, it was found that when the pressure in the fuel gas network increased, the pressure of the gas entering the unit remained unchanged, but the furnace temperature dropped significantly； Conversely, when the pressure in the pipeline network drops, the furnace temperature rises. What is the main reason for this? Is it component fluctuation? How to analyze fluctuations in fuel gas composition based on pipeline network pressure?
It is the fluctuation in the composition of the fuel gas. In case of specific issues, communicate promptly with the scheduling and fuel gas supply departments, or contact the laboratory for sampling and analysis immediately if any abnormalities are detected.
With all other conditions unchanged, by examining the opening degree of the gas pressure control valve, at the same pressure, the greater the opening of the control valve, the relatively lighter the composition; and vice versa.
When the pressure in the fuel gas pipeline network increases, some of the heavier components in the network turn into a liquid phase, resulting in the fuel gas entering the device having a lower density; the calorific value of these lighter components is also lower, which naturally leads to a decrease in furnace temperature； Conversely, the same applies. Try to avoid fluctuations in pipeline network pressure.
