We are in the process of design stage for our plant expansion and Im having trouble with the boiler stack.
Currently we have 3 nos x 12500 kg/hr boilers operating at almost optimum capacity and we are intending to add 1 more boiler with a capacity of 15000 kg/hr.
The total steam generation would likely to have 52500 kg/hr.
I need to know if our existing stack with an ID of 1200 mm if enough to handle this capacity.
Our operating conditions as follows.
Boiler Operating pressure: 14.5 bar g
Boiler Operating temp: 200 deg C
