The New York State Department of Environmental Conservation is taking comment until March 27 on an air permit change covering a major revamp of the boilers at Cornell University‘s main campus in Ithaca.
This major permit modification was submitted in order to enable the construction of two new package boilers which will be designated as Boiler #3 and Boiler #4 (Emission Sources BOI3 and BOI4 respectively). These new boilers will be dual-fueled units capable of firing natural gas or distillate (No. 2) oil. Each unit will have a maximum heat input capacity of 99.72 MMbtu/hr on natural gas or 94.86 MMbtu/hr on oil.
These new units will be equipped with low-NOx burners and an oxygen trim system. Emissions from these new boilers will be directed to existing Emission Point 00002.
Boiler #9 (a 200 MMBtu/hr package boiler) is being removed from the permit at this time. This unit was originally permitted in 2011, but was never constructed. In lieu of Boiler #9, Cornell has decided to construct two smaller boilers (Boilers #3 & #4). The rental boilers are currently vented to Emission Point 00002. The rental boilers will be used until the end of the current heating season, and are expected to be removed by April 2015.
The new package boilers #3 and #4 will be connected to the stack via the same portal used for the rental boilers. The new package boilers #3 & #4 will not be physically connected to the stack until the rental units have been permanently disconnected from the ductwork.
