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

CHAPTER I 1. Fuzzy control Fuzzy control is a practical alternative for a variety of challenging control applicationssince it provides a convenient method for constructing nonlinear controllersvia the use of heuristic information. In a sense fuzzy systems can be “trained” and can “learn” how to perform throughout a control task and are considered as intelligent control system. Fuzzy control system design is based on empirical methods‚ basically a methodical approach to trail-and-error. The

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

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

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. _____________________________________________________________________________________

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
