Today on Weekly Boiler Tips we explore how premixed burners work, the role of mesh surfaces as flame arrestors, and why adding additional materials can disrupt the burner system's efficiency. Feb. 26, ...

Some premix burner designs use either high excess air levels or FGR to further reduce NOx). FIGURE 1. Furnace temperature vs. thermal NOx level. There are several ways to supply recirculated flue gas ...

In a diffusion flame such as a candle flame, ... "Most natural-gas burners in domestic stoves and furnaces use premixed burners," he writes, hence the blue flames. The question.

“In a traditional premix gas turbine combustor, a change in fuel reactivity implies a change in flame location. In particular, higher fuel reactivity forces the flame to move upstream ...

Similarly, comparative studies using both LES and Reynolds-averaged Navier–Stokes (RANS) methods have examined the formation mechanisms of nitrogen oxides in non-premixed industrial gas burners.
