Methodology to Perform a Combined Heatingand Power System Feasibility Study for Industrial Manufacturing Facilities

摘要

This article considers combined heating and power (CHP) systems based on topping cycles, in which electricity is generated by a prime mover and heat is then recovered from the exhaust and utilized to offset all or a portion of the facility's process and / or space heating requirements. The article presents a methodology to perform a base load CHP system assessment and feasibility study for industrial manufacturing facilities as well as to determine emissions reductions that may result from utilization of such a system. In order to determine the best and most viable option for the facility in question, the proposed methodology can be used to size different systems which utilize diverse technologies and fuel sources, perform an economic analysis of each proposed option, and then compare the benefits and setbacks of each type of CHP system considered. The economic analysis will provide a broad insight as to which proposed system will show the best payback if installed. In addition to the economic analysis, the proposed methodology can be used to determine the potential reduction of emissions associated with utilization of the CHP system. Examples are presented to describe in detail the application of this methodology.
