Liquid butane will be burned. The engineer who designs the oven must calculate the highest temperature that the walls of the oven will have to withstand to choose a suitable construction material. Make the calculation assuming that the butane is fed at $25\backslash$deg C and the air enters $600\backslash$deg K$.$
