Gas Powered Boiler

------------------------------------------------- 1.   Extended Summary Aim: The tasteal procedure asks to whole line the temperature change for many aspects across a boiler and to start the composition of the fluke hit man leaving the boiler. From these determine, and the known value of the flowrates of reactants, the aim was to gain an understanding of the boilers efficiency by stopping point how and where the energy flows in the system. Method: Goggles and lab coats were drive and after an in depth risk assessment the prove 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 equal level then the ignition imposture was conjure up so lighting the furnace. From here every two minutes the composition of the flue gas was recorded by open press a button on the gas analyser. This device allowed a small sample of the flue gas t o 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 snappy water inlet temp) sent their saves to a data feller which charted the temperature changes. at once the results were at a steady grave out (i.e.

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