Converting from Steam to Gas

steam-formaldehyde sterilizer for gas penetration efficiency

SYNOPSIS A test piece is described for monitoring the performance of low-temperature steam-withformaldehyde sterilizers. Comparative tests have shown it to be more difficult to penetrate than an arterial catheter when exposed to the same sterilizing conditions. It is permanent and simple to use and maintain. The growth or non-growth of bacterial spores, in the convenient form of spore strips, i...

Power Plants, Steam and Gas Turbines WebQuest

A WebQuest is an Internet-based and inquiry-oriented learning activity. The aim of this work is to outline the creation of a WebQuest entitled “Power Generation Plants: Steam and Gas Turbines.” This is one of the topics covered in the course “Thermodynamics and Heat Transfer,” which is offered in the second year of Mechanical Engineering at the Defense University Center at the Naval Academy in ...

From natural gas to ethylene: a study on combining oxidative coupling of methane with steam reforming

طراحی حرارتی – سیالاتی، ابعادی ریکوپراتور گاز به گاز (gas to gas) میکروتوربین 200 کیلو وات

یکی از راههای افزایش راندمان حرارتی واحدهای میکروتوربینی، استفاده از حرارت گازهای داغ خروجی از توربین می باشد که این گرما در مبدل حرارتی ( ریکوپراتور) به هوای خروجی از کمپرسور منتقل شده و بدین طریق میزان سوخت مصرفی سیکل کاهش یافته و در نتیجه راندمان این واحد ها افزایش می یابد. ریکوپراتورها مبدل های حرارتی گاز به گاز فشرده¬ای هستند که با نسبت سطح به حجم بالایی، میزان انتقال حرارت ما بین گاز خروج...

Converting from ECCE to SICS

Introduction Cataract continues to be the cause of almost half the cases of blindness worldwide and the challenge to meet the needs and develop the required resources is as great as ever. Cataract surgery has evolved from couching, first practised several thousand years ago, through intraand extracapsular extraction (ECCE), to phacoemulsification. However, whatever the technique, the most impor...
