CHP MODELLING 2ABSTRACTCombined heat and power systems have a wide range of benefits to users especially in the areas of reliability, efficiency, environmental and cost effectiveness. CHP systems have over the years risen to provide increased amounts of electricity and thus considered to be one of the contributing factors to a growing global energy market. The importance of CHP cannot be stressed enough because we need to understand how they operate and in turn improve it further so that the application of such a technology can be widespread. As a result, we would be able to tell the different types of CHP systems and how well to apply them in order to suit our specific needs.Keywords; Combined heat and power systems (CHP), natural gas (NG), net present value (NPV).

CHP MODELLING 3Introduction The main purpose of Combined Heat and Power, (CHP) is to achieve high levels of efficiency during operation while also saving energy by consuming less and reducing the emission of harmful gases into the atmosphere[ CITATION Pau17 \l 1033 ]. These systems basically convertone form of energy to another and in most cases, it is mechanical to electrical energy coupled with some useful heat. They are usually used in areas such as campuses/ schools as will be seen in this paper thus offering efficiency, sustainable design opportunities and ease of system maintenance[ CITATION RBe11 \l 1033 ]. The first part in this paper highlights CHP technology and explanation of what the assessment tool is all about. Then the advantages and disadvantages of the various combined heat and power, and finally the discussion and conclusionof the results obtained from the assessment tool.Technical overview of CHP technologyCHP uses a single source of fuel or energy to produce both heat and power near or at the locationof use [ CITATION Jan17 \l 1033 ]. Such systems are usually designed to meet the standards of various energy users be it city-wide levels, industries or even buildings. It can broadly be viewedas a producer of electricity and a source of heat. There are different systems that can be referred to as CHP but all of which still have an integrated system that proves to be efficient by recovering heat at the same time producing electricity. They usually consist of four main parts namely the engine/prime mover, a generator, a system to recover heat and a control system. Heat is generated by the prime mover as it drives the engine, this heat can then be recovered at the recovery unit.

CHP MODELLING 4CHP can be driven by any fuel but natural gas has proven to be more dominant [ CITATION Kha14 \l 1033 ].figure1.showingaschematicdiagramofacombinedheat∧powersystemFigure 1 can be referenced at [ CITATION Uni13 \l 1033 ]Prime moversThese are technologies that are reliable, mature and have been proven over the years. They include reciprocating engines, gas turbines, combined cycle systems and even steam turbines. Allof which operate in a similar manner whereby the fuel is burned, mechanical energy is formed oreither steam is formed first then converted to mechanical energy. This energy in turn spins the generator which produces electricity [ CITATION Gus17 \l 1033 ].Generators and recovery of waste heatAs usual generators convert the mechanical energy received from the prime mover to electrical energy [ CITATION Zie17 \l 1033 ].The prime mover and generator both produce heat during their operations. These heat is capturedby heat recovery unit which then transfers it to the building on site.CHP assessment tool
