Abstract：

A　numerical　simulation　model　of　ORC　system　of　stationary　CNG　engine　was　built　by　using　GT-Suite　software,　and　the　dynamic　characteristics　of　expander　were　analyzed　to　determine　the　running　state　of　the　ORC　system.　The　running　performances　of　stationary　CNG　engine-ORC　combined　system　were　investigated.　The　results　show　that　the　fluctuation　of　refrigerant　mass　flow　rate　in　expander　is　obvious　during　the　engine　runs　in　low-load　region(from　20%　to　40%　of　engine　load).　The　thermal　efficiency　of　the　combined　system　increases　with　engine　load.　However,　the　increment　of　thermal　efficiency　of　combined　system　is　slight　in　the　high-load　region　of　engine(from　90%　to　100%　of　engine　load).　Compared　with　the　stationary　CNG　engine,　the　thermal　efficiency　of　the　combined　system　can　be　increased　up　to　5%　(at　the　rated　condition　of　engine),　while　the　brake　specific　fuel　consumption(BSFC)　can　be　reduced　up　to　4%(at　the　rated　condition　of　engine).　©　2016,　Editorial　Board　of　Acta　Energiae　Solaris　Sinica.　All　right　reserved.
