Dec 16, 2020 · Heat Load on Furnace. You can calculate heat load on furnace from the heating requirement of process air. Q = Air flow rate*Heat Capacity*(620 110) Q = 6000*0.25*(620 110) = 765,000 kcal/h. Considering 5% heat loss from furnace actual heat requirement will be Q = 765,000*1.05 = 803,250 kcal/h.
