Steam required to boil a substance?

  1. Mar 31, 2012 #1
    Hi there,

    I am working on a process in which I have to melt 100 kg/h of plastic. The best way we thought of doing this was to use a boiler (steam generator) to produce sufficient heat to boil the plastics in time. I am currently trying to choose the right boiler for the system. Yet, I do not know how to calculate the required mass flow rate of steam to boil the mass flow rate of the incoming plastics. Can anyone give me an equation, or explain how I can calculate this?

    First you need to know how much heat you need. Do you know the thermal properties of your plastic?
