[Gasification] What is sensible heat of Producer gas? How much sensible heat is added from Gross calorific value?

[A.Saravanakumar]

Dear All,



Producer gas heating values is 1200 kcal / nm3 @ 30°C 



In normal case 1kg wood + 1.5 kg air = 2.5 kg of producer gas ~ 2.5 m3 of producer gas @ 30°C



1m3 of producer gas = 1200 kcal



Therefore 2.5 m3 of producer gas = 1200 X 2.5	= 3000 kcal / m3 @ 30°C



In our case Producer gas outlet temperature is 	=  600°C

Producer gas outlet temperature is increased from 30°C to 600°C. Hence producer gas generated 

at 600°C in this temperature sensible heat is added. 



If the producer gas generated at 600°C How much sensible heat is added from Gross calorific 

value?
