not only radically change the energy balance of a factory‚ but also in- fluences the quality of the product. GEA PHE Systems therefore offers you a state-of-the-art and carefully matched range of equipment for evaporation‚ condensation and general heating/cooling. Thus inputted energy can be fully exploited by using modern and powerful engineering! More efficiency for your energy balance The energy requirements of sugar production are particularly high‚ waste exhaust vapours and condensates‚ for example

statements on “heating costs”. Each serves a different purpose. Purpose To analyse To explain a cause To contrast To explain an effect To explain a process To offer a solution To classify To explain advantages To explain disadvantages Thesis A home energy audit revealed that we can reduce home heating costs by $500 a year. Our home heating costs were high because of poor insulation‚ drafty windows‚ and an inefficient furnace. Homes using passive solar energy have lower heating bills than others

and development of the company Production of electrical heating elements has a more than fifty-year tradition in Hlinsko. In 1943‚ a small joint stock electrotechnical company ESA was founded. It started with production of small household appliances‚ namely cookers and irons‚ where resistant spirals of own production inserted in ceramic base were used. In 1948‚ a licence of a Swiss company Maxim-Aurau for production of sheathed tubular heating elements of flat-oval cross section has been bought. This

Electrical Q&A Part-3 Questions and Answers related to Transformer: 1. What is a transformer and how does it work? * A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. It can be designed to “step up” or “step down” voltages and works on the magnetic induction principle. * A transformer has no moving parts and is a completely static solid state device‚ which insures‚ under normal operating conditions‚ a long and trouble-free

Properties of paper Physical Properties Basis Weight or Grammage The basis weight‚ substance or grammage is obviously most fundamental property of paper and paperboard. The Basis weight of paper is the weight per unit area. This can be expressed as the weight in grams per square meter (GSM or g/M2)‚ pounds per 1000 sq. ft. or weight in Kgs or pounds per ream (500 sheets) of a specific size. Paper is sold by weight but the buyer is interested in area of paper. The basis weight is what

EXPERIMENT 7: PERCENTAGE OF OXYGEN IN KClO3 Introduction: In this experiment you will determine the percentage of oxygen in potassium chlorate. You will calculate the theoretical value from the chemical formula and compare your experimental value to the theoretical value. Background: When potassium chlorate (KClO3) is heated‚ it undergoes chemical decomposition. Oxygen gas (O2) is given off and potassium chloride (KCl) remains as the residue. The equation for the decomposition of potassium

EXPERIMENT NO. 10 COMPOSITION OF POTASSIUM CHLORIDE ABSTRACT The aim of the experiment was to look for the percentage composition of the elements present in the decomposition of potassium chlorate (KClO3) and to find out what the residue after heating was. After performing the experiment the researchers found out that there were about 66.14% of potassium chloride (KCl) in KClO3‚ and they also deducted that the residue was actually KCl. _____________________________________________________________________________________
