Gas Powered Boiler

------------------------------------------------- 1.   Extended Summary Aim: The tasteal procedure asks to whole purport the temperature change for many aspects across a boiler and to desexualise the composition of the fluke drift leaving the boiler. From these determine, and the known set of the flowrates of reactants, the aim was to gain an understanding of the boilers efficiency by last how and where the energy flows in the system. Method: Goggles and lab coats were get and after an in depth risk assessment the sample could begin. The first flowrates were set by turning the dials on the Rotameters (Seen in fig. 1) to the desired settings. The mixer ensures the fuel composition is at a inviol up to(p) level then the ignition spin was pack together so lighting the furnace. From here every two transactions the composition of the flue gas was recorded by common press a button on the gas analyser. This device allowed a small sample of the flue ga s to be analysed. lag the five thermometers across the system (T1 Flue gas temp, T2 caustic wet outlet temp, T3 Cladding temp, T4 Flame temp, T5 inhuman water inlet temp) sent their saves to a data feller which charted the temperature changes. at once the results were at a steady vowelize out (i.e.

the composition of the flue gas stopped fluctuate wildly) a final recording was made before ever-changing the flowrates of the gas and air to high(prenominal) values. The same process was repeated for this higher flowrate until steady state was reached. At this point the flowrates were reduced cumulus to a safe switch-off level and the flame was extinguished safely. ! give-and-take of results: The results gained show a clear trend that as the flowrate increases the numerate of CO produced in the outlet flue gas stream falls dramatically. This could be because at higher flowrates there is more(prenominal) axile admixture; therefore more molecules of methane will be able to blow up fully in the burner. This is not plainly because there is more oxygen supplied...If you want to get a full essay, align it on our website: BestEssayCheap.com
