emission sampling ports on stacks of boilers, furnaces and heaters
emission sampling ports on stacks of boilers, furnaces and heaters
(OP)
Dear All,
In one of the job I have to install emission sampling ports on stacks of boilers, furnaces and heaters . I have attached the standard clause with this thread.
First of all I need to understand where the sampling ports should be located. Is it 8 Diameters from the Top of the stack or is it 8 diameters from the bottom?
Secondly how can i determine if the flow inside a stack is cyclonic or not?
thanks

You can do an EPA test to determine if the flow is cyclonic:
