Flue gas composition is significantly affected by the combustion conditions. Concentration of gaseous species upon firing 1.7% S coal (chemical composition is given in Table 1) was calculated at 1300 °C, assuming thermal equilibrium, and presented in Figure 2 as a function of airfuel ratio. In this chapter, airfuel ratio is defined by the ratio of their weights; airfuel ratio of 10

Reheat Temperature - an overview | ScienceDirect Topics

20/11/2001 · Depending on the outdoor temperature, the pressure differential needed to drive the flue gases up and out of the furnace is somewhere between 1 and 5 Pascals (0.004 to 0.020 in. of water column [wc]). What this means is, as flue gases leave the furnace, they must be at -1 to -5 Pascals relative to atmospheric pressure.

Flue Gas Monitoring and Control. Flue gas monitoring and control using variable speed drives can reduce the energy use for the flue gas fans, reducing the heat losses in the flue gas. The flue gas flow varies over time, which makes the use of variable speed drives possible. Flue gas VSDs have been installed in various countries (e.g., Germany, UK).

The change of pressure at t = 900 s is clearly visible in α.Note that the smoothed α(t) curve has a small wiggle around t = 900 s, just before the drop, which is an actual phenomenon, only slightly exaggerated by the cubic spline approximation.. This example shows that α in gas quenching has to be treated as a function of time, to represent the quenching conditions correctly.

The Importance of Operating with Proper Furnace Draft

There is another method of injecting flue gas into the furnace where the take-off point is much nearer to the furnace, which means the flue gas has a much higher temperature but much lower pressure. Recirculation fans are provided to generate pressure higher than the furnace. The gas recycling damper does the rest of the things.
