Furnace Shell Spray Cooling Design

  1. Feb 22, 2012 #1
    Hi,

    Please help anyone.

    The furnace shell will be cooled using spray cooling along the outside wall surface from a reservoir tank and then the water is collected below through troughs. I need to calculate the temp of the water down the shell when collected if it needs extra cooling as it is pumped back to the reservoir.

    Knowns;
    1) 2 mm water film on shell surface
    2) Dry bulb temp = Max 50 / Min 6 D.C.
    3) Wet bulb temp = 28 D.C.
    4) Wind velocity = 50 m/s

    I dont know where to begin, please send me in the right direction, very rusty in heat transfer.

    Thanks!
