Analysis of a bladeless steam turbine for use in a domestic combined heat and power system Peter Burton Edinburgh Napier university Abstract This report analyses the suitability of a bladeless ‘Tesla’ type steam turbine to determine its merit for use in a domestic combined heat and power system. A physical prototype was developed and built so that cost and performance data could be determined. With this done‚ a cost analysis was prepared to evaluate its performance when integrated into a

The Greek engineer who invented the steam engine 2‚000 years ago Almost two millennia before the rest of humanity entered the industrial age‚ the Greek inventor Hero invented the steam engine‚ wind-powered machinery‚ and theories of light that couldn’t be improved for centuries. And then he invented some really crazy stuff. Scientific geniuses have to pull off a tricky balancing act before they’re even born. Great minds like Albert Einstein or Isaac Newton were born at precisely the right time

Isolation of Acetyleugenol (Clove Oil) from Cloves Purpose In this experiment‚ you will obtain the essential oil from cloves by steam distillation. You will then separate a component (acetyleugenol) from the oil by liquid-liquid extraction. Finally‚ you will isolate the acetyleugenol by using a rotovap for reduced pressure distillation‚ which will remove the organic solvent (dichloromethane). Background Whole cloves contain between 14% and 20% by weight of essential oils‚ but

It is although believed that crude forms of distillation‚ the main method that essential oils are now obtained‚ were practiced thousands of years ago in Persia‚ Egypt and India. Distillation was used mainly for the extraction of exotic flower waters. The medicinal use of plants and their extracts in India has been continuous from 5‚000 years ago to the present day

Isolation of the Major Component of Clove Oil Pre-Lab Questions: 1.) Briefly explain the concept of steam distillation. What is the difference between a simple distillation and a steam distillation? When a mixture of two immiscible liquids are distilled it is referred to as codistillation. This process is referred to as steam distillation when one of the liquids is water. This distillation is used to separate organic liquids from natural products and reaction mixtures in which the final product

In this experiment‚ eugenol was isolated from a sample of cloves using a series of techniques including steam distillation‚ solvent extraction‚ decantation‚ and evaporation. A simple-steam distillation apparatus was assembled and a mixture of water and cloves distilled to separate the eugenol from other clove components. The use of a solvent‚ Methylene Chloride was then used to isolate the Eugenol‚ and
