WebAlso, lower combustion temperatures reduce the fouling and corrosion of heat-transfer surfaces. (Fouling is the phenomenon of coal ash sticking to surfaces.) Ash from a fluidized-bed combustion system is amorphous—that is, ... the temperatures developed inside the furnace are high (up to 2,150 °C, or 3,900 °F). At such high temperatures ... WebAir leakage through furnace openings, particularly moving parts such as furnace doors, can result in large heat losses. For a melting furnace without pressure control, even a ¼-inch …

Webfurnaces tend to emit more of these pollutants than larger combustors. This is because smaller units usually have a higher ratio of heat transfer surface area to flame volume than larger combustors have; this leads to reduced flame temperature and combustion intensity and, therefore, lower combustion efficiency. WebThe main reason was that the density of the fuel entering the furnace was lower than burning corn, board, or other high-density fuels, so the residence time in the furnace was short. Also, the gas temperature in the dense phase zone had no obvious sudden changes, indicating that the combustion share in the lower part of the furnace was low.
