Marcet Boiler

The apparatus used was a building block of Marcet kettle hole and water. The unit of Marcet tympani consists of a stainless steel pressure level vessel fitted with high pressure immersion electricalheater, control panel, a guard relief valve, water inlet port & valve, laggard thermionic vacuum tube pressure gauge, temperature and pressure touchstone devices.Before starting the experiment a quick inspection was performed to picture the unit is in meet operating condition. The unit of Marcet Boiler was later connected to the hot power supply. Valve at the belong away port and the direct spate tube were opened. after that, the boiler was filled with distilled water by means of the race port and the water level was madesure to be at around half of the boilers height. Then, the valves at the level caprice tube were unlikable and the power supply is turned on.The temperature ascendancy was set at 185.0 °C which is slightly above the rate boiling point of the water at 10.0 sedan(abs). The valve at track down port was opened and theheater was turned on. The valve at the level cognizance tube are made sure to be closed in(p) beforeturning on the heater as the sight tube is non designed to withstand high pressure andtemperature. The rise of pop off temperature was observed as the water boils. The steamfrom the valve was allowed to come out for 30 seconds before the valve was closed.

Thisstep is important to remove aviation from the boiler as the accuracy of the experimental resultswill be significantly affected if activate is present. The steam temperature, gauge pressure at1.00 run (abs) and time understand for the steam to reach 1.00 bar (a bs) were enter. Thisstep was repeated by ! setoff the interval of pressure with 0.5 bar (abs) until the steam pressure reaches 10.0 bar (abs). After that, the heater was allowed to cool down to roomtemperature. All the results were preserve and tabulated under the table below. Graph of temperature against absolute pressure was plotted. inscription of the slope of the graphwas made.
