... Abstract Principle use of the pilot flame is to control combustion in systems having continuous ignition and maintain main flame by providing heat or chemical species and prevention from cold air. This paper study the numerical simulation of non-premixed methane/air piloted flame comparatively...

... Ultra-low concentration coal bed methane is difficult to utilize due to its low concentration and fluctuant flow. A laboratory fluidized bed reactor was employed to burn ultra-low concentration coal bed methane. The temperature and pressure characteristics during combustion were studied...

... critical boilers are introduced in this paper, they include the single-furnace with double fireball corner fired furnace, the wall fired furnace and the tower-type furnace. The low NOx combustion technologies have been widely used to face the environmental challenges. The low NOx technologies employed...

... 25 11 2008 Power plants concerned with lowering NOx emissions are making tremendous changes to accommodate EPA regulatory requirements. A substantial number of these changes include the expansion and upgrade of the plant combustion oxygen measurement equipment. There is a striking...

... 28 10 2008 The real time, in-situ measurement of excess oxygen and temperature in the radiant heat zone of a boiler or furnace provides a window for viewing combustion conditions closest to the source. Excess oxygen and temperature measurements, taken at strategic sample points around...

... effect and radiation reabsorption. So, we made detailed chemical kinetic calculations including the effect of radiation reabsorption to clarify the premixed laminar flame speed of such mixture as one of the most important properties for controlling the combustion. The concentrations of mixture are varied...
