Question 1 1 pts You are asked to select the interior cladding material for a furnace. What piece of information would be most useful in making this decision? O a) The adiabatic flame temperature of the mixture O b)The fuel's heat of combustion O c) The expected normal operating temperature O d) The enthalpy of reaction and flow rate of fuel D | Question 2 1 pts The amount of air to a furnace is increased to 200% excess from 100% excess, what will happen to the adiabatic flame temperature? O a) It will increase. O b) It will decrease O c) Not enough information is given

Explanation / Answer

1) Ans: A

based on adiabatic flame temperature cladding material is selected. Because it has to with stand to that temperature.

2) Ans: B

increase in excess air (100% to 200%) there will be decrease in flame temperature. Because heat generated in the reaction is abrobed by excess air result low flame temperature at the exit of furnace.

3)Ans: C both are same
