Combustion performance of domestic gas cookers with swirling strip-port and normal round-port on various natural gas compositions

Performance Optimization of Gas Turbines Utilizing Four-Port Wave Rotors

Many studies have demonstrated the benefits of wave rotor application in gas turbine engines. The general performance trends have been generated; however, there is a question of where the most appropriate design space is. The aim of this investigation is to answer this question by showing the generalized performance trends of several four-port wave rotortopping configurations in a multi-dimensi...

hazard evaluation of gas condensate stabilization and dehydration unit of parsian gas refinery using hazop procedures

شناسایی مخاطرات در واحد 400 پالایشگاه گاز پارسیان. در این پروزه با بکارگیری از تکنیک hazop به شناسا یی مخاطرات ، انحرافات ممکن و در صورت لزوم ارایه راهکارهای مناسب جهت افزایش ایمنی فرا یند پرداخته میگردد. شرایط عملیاتی مخاطره آمیز نظیر فشار و دمای بالا و وجود ترکیبات مختلف سمی و قابل انفجار در واحدهای پالایش گاز، ضرورت توجه به موارد ایمنی در این چنین واحدهایی را مشخص می سازد. مطالعه hazop یک ر...

Natural gas: physical properties and combustion features

The majority of natural gases are mixtures of saturated hydrocarbons where methane prevails; they come from underground accumulations of gases alone or gases associated with oil. There are thus as many compositions of natural gases as exploited hydrocarbon layers. Apart from the methane which is the prevailing element, the crude natural gas usually contains decreasing volumetric percentages of ...

Simulation of Dual Fuel Combustion of Direct Injection Engine with Variable Natural Gas Premixed Ratio

Nowadays, the major challenge of diesel engines development is simultaneous nitrogen oxides and soot emissions reduction without the thermal efficiency drop. Hence, different combustion concepts should be investigated to reach optimum emission and performance conditions in diesel engines without expensive aftertreatment systems. This paper presents the results of a study on a dual fuel (DF) eng...
