A new designfor a propane grill uses preheated air to improve its performance.The grill flame operates with an equivalence ratio of 0.9 and theair and fuel are heated to 450K prior to the burner. A ceramicplate is above the burner for radiating heat to the food on thegrill. You are told that the plate is capable of withstanding 2200K. Assuming that the flame directly impinges on the plate, are youcomfortable with this design? Show calculations to back up yourreasoning.
