**Diesel
Generator Sets : Stack Height**

The minimum height of stack to be provided with each generator set can be worked out using the following formula :

H = h + 0.2 x / Ö KVA

H = Total height of stack in metre

H = Height of the building in meters where the generator set is installed

KVA = Total generator capacity of the set in KVA

Based on the above formula the minimum stack height to be provided with different range of generator sets may be categorised as follows :

For Generator SetsTotal Height of stack in metre

50 KVAHt. Of the building + 1.5 metre

50 - 100 KVAHt. Of the building + 2.0 metre

100 - 150 KVAHt. Of the building + 2.5 metre

150 - 200 KVAHt. Of the building + 3.0 metre

200 - 250 KVAHt. Of the building + 3.5 metre

250 - 300 KVAHt. Of the building + 3.5 metre

Similarly for higher KVA ratings a stack height can be worked out using the above formula.
