Regarding hydraulic jet pumps

In my workplace, the hydrogen-to-chlorine ratio in the two-in-one synthesis furnace is between 1.6 and 1.7; however, the pressure inside the furnace remains within 1 KP, the flame color is normal, and production is proceeding as usual. But I’m worried that problems might arise if this situation continues. Could anyone tell me what might be the cause of this issue? 1. Is the flow meter inaccurate? 2. Is the hydraulic jet pump set too high? ? (We are at -1~2 KP), so I want to adjust the hydrogen flow rate and lower the hydraulic jet pump, then check whether the pressure inside the furnace is normal This idea is feasible; if not, what can I do to reduce the ratio? Also, what pressure level for the hydraulic jet pump is necessary to accurately reflect the actual intracranial pressure? ? What is the relationship between the pressure of the hydraulic jet pump and the furnace pressure? # , , &
We have two sets of furnaces for hydrochloric acid production. The first set is from Roland; its ignition system does not include a hydraulic pump. At the beginning, a fan is used to create negative pressure, and once ignition is successful, the fan is turned off, leaving the furnace pressure at around 1 KP. Later, for the second set equipped with a domestic two-in-one furnace, the piping was arranged in the same way as that of the first furnace, and no hydraulic pump was installed either; the furnace pressure during normal operation was also around 1 KP. In my opinion, the furnace pressure is related to the following factors: 1. The ratio of hydrogen to chlorine; an excess of either gas will cause the furnace pressure to rise. 2. The concentration of hydrochloric acid – if the concentration is too high and absorption is incomplete, this can also lead to an increase in furnace pressure. If the flame is white, it indicates an excess of hydrogen, while a yellow flame suggests an excess of chlorine. If the pressure of the hydraulic pump is reduced, the furnace pressure will definitely increase. If it is necessary to adjust the ratio, experienced technicians on site can observe the flame and instruct the control room to gradually reduce the amount of gas to be decreased.
Hehe, it seems like your answer isn’t what I asked. Anyway, thank you anyway; what you said was very useful. Is this question that difficult~?:) Members of Haichuan Technology, could the expert team help answer it?
A low furnace pressure is not harmful to the furnace, but it hinders subsequent absorption. The furnace pressure cannot be adjusted by changing the ratios; those ratios must remain fixed. An excessive amount of hydrogen, as you mentioned, is very dangerous for the exhaust gases
