Regarding heat duty
Thread Content
For example, in the case of an RGibbs vaporization furnace, does its heat duty refer to the heat it generates, with a negative value indicating that heat is being produced? Is net heat duty the heat generated minus the heat incoming? And if the value is positive, does it mean heat is flowing in? Thanks, I’m really confused
It should be a negative value. Take another look at the software’s Chinese instructions; it should be calculated in this way: h = h0 – h1. If the device you want to simulate releases heat, then no heat needs to be inputted into it, so h0 = 0. If that device releases 50 KJ of heat, then h1 = 50 KJ. In that case, clearly h = -50 KJ. Refer to the instructions for the model you’ve chosen, using what I’ve said as a guide
In RGibbs’ vaporization furnace, the heat duty does not refer to the heat generated by the reaction itself, but rather to the heat that is removed from or supplied to the system from outside.
It should be heat that requires external supply or removal
