    HOW PLATE HEAT EXCHANGERS BEAR THE THERMAL EXPANSIONS

    OK 821326 you really mean 900 degrees C. At first i thought, you mean 90 degrees C. At the starting up period, the varming up period, there is a problem with thermal expansion. May be you can slowly heat up the MS, so that the materials can follow eats other...

    HOW PLATE HEAT EXCHANGERS BEAR THE THERMAL EXPANSIONS

    Some thoughts about it. The mentioned temperature is extreme high for gasket plates. For brazed plates,it is a block. The temperature is a middle temperature of the temperatures. All the plates do the same, follow etch other, except the endplates. The endplates are normally plane plates. With...

    double walled tube applications ideas

    Also Holland have legislated double wall constractions to prevent contamination of drinking water in case of failure. Double wall shell and tube or double wall plate heat exchangers.

    PHE Hot and Cold film Heat Transfer Coefficents

    Dear SamOntario Some of your PHE data are wrong, the heat in is the same as the heat out.The 50 000 (120 – 70) should be the same as 100 000 (85 – 60), so you have heat balance! One of your temperatures or flow is wrong. Probably the flow data. When you have the right temperatures and flow...

    Plate & Frame Heat Exchanger Leaking...

    Hi murphymok I would try the following steps: 1 Steam inlet at the top. 2 Clamp to the minimum measure, between the frame plates, this measure is often stated on the machine plate, and on the assembly drawing.And try again. 3 If you don’t have the measure, you had to ask the manufacture for...

    Pipe Pile Driving

    Hello Fuzzy I am not a geotechnical, so I feel free to come up with a perhaps crazy idea. The idea is to have a small steam pipe with a one-vay valve in the closed end pipe. When adding some amount of steam, a steam bubble, the steam bubble lift the above water column and condense. When the...

    Water Column Separation Engine ?

    May I ask you,will my WCS engine work? Imagine, a long water filled pipe or cylinder with a sealed piston in connected to a crankcase mechanism. By pushing the piston and the water column and suddenly stop or turn the piston. The water column moves further (more feets), create vacuum...
