Our project is an existing manufacturing project and we have 1 existing steam boiler and will install 1 new.
Both steam boilers will supply steam for process equipment only not for space or hot water heating.
Our questions are:
- Can we do the exceptional calculation to claim energy saving from these process boiler? Our boiler are high efficiency one with economizer and condensate return.
- If we can claim saving then can we use the boiler efficiency in ASHRAE 90.1 table 6.8.1F as baseline efficiency?
- To declare the efficiency of the existing boiler, can we use their specification with derating factor or we need to do the actual measurement of boiler efficiency?
