Horizontal pipe pressure measurement
Thread Content
To improve the straight-run uniformity coefficient of the coke oven, it is first necessary to ensure that the pressure in each row of horizontal tubes is appropriate, which raises the issue of measuring the pressure in these horizontal tubes. Select a standard transverse pipe; when taking measurements, use the pressure of this standard pipe as a reference to determine the relative pressure difference of the other transverse pipes. What is an appropriate range for the relative pressure difference of these transverse pipes?
It should be determined based on the pressure in the horizontal pipe; generally, it should not exceed 5%
Our factory has never done this before; could an expert please explain how to measure it and what the specific standards are?
I heard an experienced teacher say that the pressure in horizontal pipes should generally be kept around 800!
At the end of the gas cross-pipe, there is a plug used to measure the pressure in the cross-pipe; during measurement, this plug is removed and connected to a measuring instrument. Of course, the valve of this combustion chamber must be closed before unscrewing the plug. Turn it on during measurement. It can be measured using a U-tube manometer or an inclined pressure gauge. Inclined pressure gauges have lower errors; they can also be connected directly to a single lower nozzle in the combustion chamber for measurement, requiring tight sealing.
