WHENEVER I MAKE A HEAT BALANCE OF GRATE COOLER THE CALCULATED TEMP. OF SEC. AIR COMES TO ONLY 400-500 DEG. WHILE THE TERTIARY AIR TEMP. IS 900-930 DEG. BUT AS WE KNOW THAT SEC. AIR TEMP. IS ALWAYS GREATER THAN TA TEMP. BY 70-150 DEG. AS SHOWN IN CCR. WHY WE GET A LOWER VALUE FROM THE BACK CALCULATION? IS THERE ANY MISTAKE IN CALCUALTION ? ANY OTHER METHOD FOR MAKING THE EXACT HEAT BALANCE OF COOLER WITH BACK CALCUALTIONS ETC.? PL. SUGGEST
