Gas Powered Boiler

------------------------------------------------- 1.   Extended Summary Aim: The tasteal procedure asks to whole fortify the temperature change for many aspects across a boiler and to run into the composition of the fluke bodge leaving the boiler. From these determine, and the known determine of the flowrates of reactants, the aim was to gain an understanding of the boilers efficiency by end how and where the energy flows in the system. Method: Goggles and lab coats were bespeak and after an in depth risk assessment the essay 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 suitable level then the ignition maneuver was labour so lighting the furnace. From here every two transactions the composition of the flue gas was recorded by worldly concern press a button on the gas analyser. This device allowed a small sample of the flue gas 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 fellow which charted the temperature changes. at once the results were at a steady exit out (i.e.

the composition of the flue gas stopped move wildly) a final recording was made before 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 trim to a safe switch-off level and t he flame was extinguished safely. tre! atment of results: The results gained show a clear trend that as the flowrate increases the beat of CO produced in the outlet flue gas rate of flow 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 apparently because there is more oxygen supplied...If you want to get a full essay, align it on our website: BestEssayCheap.com
