    High Temperature Experiment set-up

    I need to test a sodium wicking system in high temperature and agitated conditions. The experiment setup seems like it is going to be pretty complicated, however, and I need some direction on where I might get a glass set-up that I could modify. The set-up is as follows: Solid sodium pellets...

    What Flexible Seal Can Withstand 500°C and Allow Linear Motion?

    I am working on a project where I need a high temperature sealing element. You can see the system in the attachment. My moving object is moving linearly in a motion slot which is constructed on a sheet metal plate. But the surrounding temperature in this process is 500 C degree and there...

    Reaction Rate Order for High Temperature Gas-Solid Reactions

    Hello chemists! In the classical treatment of reaction kinetics, the overall reaction rate is usually written as a constant times the concentration of species raised to some power (called the order of reaction for that species). It is impressed in high school level students that this reaction...

    Packaged milk heated to high temperature

    Yesterday they were showing a kind of documentary on how packaged milk is processed and where they mentioned that at a stage milk is heated to a high temperature for a few seconds to kill all bacteria present without affecting the quality and nutrients of milk. I don't exactly remember the...

    How is high temperature reactor design different?

    I think its common knowledge that the next generation of nuclear reactors are going to operate at much higher temperatures than current designs in order to get away from the Rankin cycle and take advantage of thermochemical cycles, but what is it that makes high temperature reactors (HTR)...

    Heating solid to high temperature

    Hi, I want to electrically heat a uniform block of a known material to a high temperature (about 2000 K). I want to get a rough idea of how much electrical energy I need to supply to raise the material to this temperature so as to gauge what apparatus I will need. How would I go about this...

    High Temperature Reactor Fuel Elements

    Folks, this is my first thread in this forum. I'm writing my PhD about HTR-Fuel Elements. I'm not quite sure if anyone in this forum knows about this sort of fuel which is totally different to "normal" fuel. Anyway, I'm looking for informations about research in the US (or global) what...

    High temperature and pressure steam is used in turbines

    I did thermodynamics I and II 50 yrs. ago so help me out here. I note that high temperature and pressure steam is used in turbines and presumably the higher, the better the efficiency. My question is, is the temperature doing anything or is it only necessary to produce the high steam pressure...

    Why do I shiver when I have a high temperature, not when I have a low one?

    I'm sick and running a fever. If I take an Advil and my fever goes down, I stop shivering, but as the medicine starts wearing off, I begin to shiver more. I thoguht shivering was a mechanism designed to raise you're body heat, so it doesn't make sense that when I'm running a 103.8 temperature...

    High temperature superconducting switches

    Although low temperature superconducting (LTS) switches are pretty common nowadays (used in MRI magnets etc), HTS switches are far less so, in fact I'm wondering whether the one I built recently is the world's first? Does anyone know otherwise? Does anyone care? (I doubt it). Also, is this...
