Background
The waste heat resource belongs to secondary energy, and is a product obtained by converting primary energy or combustible materials, or the heat left after the heat generated in the fuel combustion process is finished in a certain process.
The flue gas waste heat recovery device of the sintering cooling system mainly recovers the sensible heat temperature of the sintering ore, the change value of the waste gas temperature of the cooling machine is 300-450 ℃, and the flue gas waste heat recovery device accounts for a great proportion of the total heat. In the sintering step, the temperatures of the sintering exhaust gas and the exhaust gas released during cooling are different depending on the combustion conditions of the sintered ore on the sintering machine. When the sintering ore is not sufficiently combusted, the temperature of the waste gas released by sintering is overhigh, and when the combustion is violent, the temperature of the waste gas released by a cooling link is lower. The main reason that the temperature fluctuation range is large is that the air volume of the waste heat recovery hood penetrating through the material layer changes, if the air permeability is too good, the air volume passing through is large, the recovery and the reutilization of the sintering residual heat are not very beneficial, and meanwhile, the problem that the sintering residual heat recovery link needs to pay attention to and solve is also the main reason.
