Project Description:
Proposes to research the feasibility of using a variable, partial, recuperator exhaust by-pass on a natural gas fired microturbine that would allow the turbine to be used for absorption cooling, space heating and power generation in commercial buildings.
Proposed Outcomes:
§ System design
§ Model of building profiles for energy supply, power demand and thermal demand.
§ Economic analysis of the proposed system.
§ Feasibility analysis of microturbine exhaust diversion system.
Anticipated Benefits:
§
This technology seeks to optimize the energy efficiency
of microturbines in commercial building applications, which could reduce their
energy consumption from the grid by up to 80% by shifting the load to natural
gas.
§
It is projected that the proposed system could achieve
a combined cycle peak efficiency of 85% with an average annual efficiency of
55%.
§ Projected payback period is estimated to be between 1.8 and 3.9 years depending on the amount of waste heat that can be utilized.
