Which of the following variables affects the furnace capacity ?
Correct answer: D. All A., B. and C.
- A. Temperature of flue gas
- B. Thermal conductivity of stock
- C. Thickness of heating stock
- D. All A., B. and C.
Explanation
Furnace capacity depends on the available heat in the flue gas, the stock's ability to conduct heat inward, and the distance heat must travel through the stock. Increasing stock thickness generally slows heating, so temperature, conductivity and thickness all matter.
