Show o rate to provide turbulent mixing at all air flows and flame shape control. The fuel/air mixture is expelled into the furnace through a refractory throat section. The refractory throat re-radiates heat to the fuel/air mass to promote rapid combustion, stability and can by preselected configuration, be used to shape the flame envelope to the particular furnace. Using a conventional register burner, allows the inclusion of gas and/or liquid fuels for combustion, with or as an alternate to the solid fuel. INSTALLATION This particular installation is fairly typical of our ninety solid fuel burners installed over the last nineteen years. The installation is at a Williamette Industries particle board plant. The burner replaced a gas burner on a conventional 35,000 PPH Babcock and Wilcox "D" type packaged boiler. This is the second heat source in the plant to be converted from natural gas to wood and gas capability. The wood fuel fired is sanderdust, from their particle board process. Fuel particle size is 1/32 inch or less. Moisture varies between 3 and 5 percent by weight. Ash content is usually less than 1 percent though this varies with the type of binders used in the board and can go as high as 10 percent on occasion. » 27-10 |
