Effects of Flame Temperature on Combustion Instabilities of a Premixed Burner
Combustion instabilities in gas turbine has been a major setback in the quest for efficient and clean combustion. Accurate characterisation and prediction of these disturbances is required to suppress them either at the design stage or in a close loop control when the system is in operation. The use of flame transfer functions has been a common approach in different literatures. Flame temperatu...
متن کاملCyclic flame propagation in premixed combustion
In experiments of hot surface ignition and subsequent flame propagation, a puffing flame instability is observed in mixtures that are stagnant and premixed prior to ignition. By varying the size of the hot surface, power input, and combustion vessel volume, it was determined that the instability is a function of the interaction of the flame, with the fluid flow induced by the combustion product...

متن کاملSimulation of Nitrogen Emissions in a Premixed Hydrogen Flame Stabilized on a Low Swirl Burner
There is considerable interest in developing fuel-flexible, low emissions turbines for power generation. One approach is based on burning a variety of lean premixed fuels with relatively low flame temperatures. Such flames can be stabilized in a low swirl burner configuration, for example, using a variety of fuels such as pure hydrogen and hydrogen-seeded hydrocarbon mixtures. However, many hyd...
متن کاملImage-Based Flame Control of a Premixed Gas Burner Using Fuzzy Logics
This paper presents an application of fuzzy logics for controlling the combustion flame of a premixed gas burner. The control objective is to achieve a good characteristic of combustion flame by visualizing the colors of the flame while maintaining its size as desired. The fuzzy logic controller adjusts the flow rates of gas and air independently through two stepper-driven needle valves. A CCD ...
