Combustion The uneven flame in the top left photo has cold spots near its center and lower temperatures around its perimeter where heat transfers take place. It is in these cold areas where soot is formed. This is a situation in which there will be unburned fuel in the form of soot and carbon monoxide in the stack. When excess air is increased to improve combustion, energy goes up the stack. The flame in the bottom left photo is burning homogenized fuel with 7% boiler water blow down. It has the uniform flame associated with complete combustion. The perimeter of the flame is almost as hot as the center, resulting in maximum heat transferred to water side. The micro explosions of the water droplets disperse the fuel and less energy is lost heating excess air. There is also less particulate matter in the stack. Fuel required per unit of energy can be significantly decreased by the use of homogenized fuel. Particulate matter can also be eliminated. A soot-free fireside significantly improves heat transfer (The EPA has determined that 1/8" of soot will reduce the transfer of heat by 8%. This is quite a reduction in efficiency). A more efficient burn requires less oxygen, which means that less heat is lost inside the stack. Less excess air also reduces the oxygen available for the formation of NOx. The top photo is combustion of regular #6 fuel with a burnout temperature of 2084°F. The bottom photo is combustion of homogenized #6 fuel injecting 7% boiler blow down water with controlled droplet sizes of 4 to 7 microns with 100% dispersion. The combustion burnout temperature is 2280°F, an increase of 196°F above the combustion of regular #6 fuel. The micro-explosions of water droplets at initial combustion completely shatters the oil droplet to a larger burning area and create secondary atomization with the result of the droplets taking on the appearance of a burning spray. Homogenized #6 fuel with boiler blow down injection has a burnout time which is 6:1 greater than that of regular #6 fuel. The reduction of 02 required increases the fireside temperature above the melting point of vanadium. For additional information please Contact Us. |
