    Regulate Incoming Steam Pressure

    there are two producers attached on the steam header, one from the coal-fired boiler, the other from the waste heat boiler of sulfuric acid plant. there is no problem with the steam coming from the sulfuric plant, as it can maintain a pressure of 42ksc, the problem is with the coal-fired boiler...

    Regulate Incoming Steam Pressure

    the problem is the steam pressure coming from the coal-fired boiler is often lower than the steam header pressure. How can i ensure that the pressure at the header is maintained?

    Regulate Incoming Steam Pressure

    We have steam from coal-fired boiler and steam from waste heat boiler of sulfuric acid plant, all connected on a common header. The problem is, the pressure of steam coming from the coal-fired boiler is fluctuating and is almost always < 42ksc, while that coming from the sulfuric acid waste heat...

    Hello guys, i work at a fertilizer plant, and as i go over the P&ID's looking for the schedule numbers of pipes existing in the plant, it seems that i can't find it in the drawings. I looked for the data sheets of the valves that are in the plant and found out that the valves has corresponding...

    NPSH and the validity of siphoning effect

    Thanks Latexman, the one thing i ignored was taking the pressure at the highest point in the piperack, i will look into that. By the way, the pump is centrifugal. BigInch, please elaborate on putting a booster at the tank

    NPSH and the validity of siphoning effect

    We have a project which is to construct and additional storage tank for sulfuric acid adjacent to the existing tanks. It has been proposed that the existing transfer pumps be used for the additional tank so as to avoid additional cost. It turned out that the said proposal is plausible because...
