My project involves a propane-fired combined heat and power system that is offsetting the space heating load for an oil boiler. How should I calculate the MMBTU value for the Application?
Estimate the space heating MMBTU value from the CHP system (converting the propane using the conversion factors in Appendix I). For example: If your CHP analysis shows that the system will provide X MMBTU for space heating, this is the value for the Application.& The electricity production from the unit is seen as the primary function for the CHP unit.
