An oven with a radiant heater for drying painted metal parts on a moving conveyor belt is designed as shown in Figure P8 36 The length of the heating section is 3 m and the heater temperature is 425 C The sidewalls are insulating and it is determined experimentally that the conveyor belt and parts attain a temperature of 120 C The belt part combination has an effective emissivity of 0 8 and the radiant heater surface has 0 7 Calculate the energy supplied to the heater Be sure to consider the radiation that is lost from the ends of the channel Take the surroundings as a blackbody at 25 C
