A grain dryer consists of a long semicireular duct of radius R= 1 m. One-half of the base surface consists of an electrically heated Refractory oven wall plate of emissivity ep = 0.8, while the other half supports the grain to be dried, which has an emissivity of ɛg = 0.9. In a batch drying process, the temperature of the grain is Tg= 330 K, and 1500 W/m of energy must be supplied to the grain (per Grain Heater plate meter of oven length). What is the required temperature of the heater plate? A grain dryer consists of a long semicireular duct of radius R= 1 m.
