Hello everyone,
I was trying to find if there is a specification or standard that specifies the minimum stack height above the building for a direct fired heater.
The most I found was 2 things:
1- CSA specifying that the minimum requirement is 1.2 * building peak height. However, this is for compressors. Heaters wouldn't be producing as much NOx as compressors, so I'm not sure if the is a different specification for fired heaters.
2- API 560 (Fired Heaters) section 9.2.1.2 specifies that " The minimum height above grade level and the exit gas velocity will be specified by the purchaser.".
Anyone has additional information as to if there is a different requirement for fired heaters than for compressors?
Thank you
