Elimination of outdated furnaces of various furnace fuel consumption are quite different. According to statistics, Hunan kiln advanced equipment, different type of kiln fired clay, high alumina clinker fuel consumption per unit of product are shown in Table 1, a different type of kiln firing products unit finished fuel consumption in Table 2. Table 1 different type of kiln fired clay, high alumina clinker per unit of product coal fuel consumption table kg / t product Rotary kiln vertical shaft kiln soil clay clinker kiln clinker aluminous 140-160 65-80250-300 200 -280--400-500 Thus, lime kiln advanced equipment, kiln calcination of raw materials, down draft kiln firing products, there are high energy consumption and serious environmental pollution, harsh operating environment issues. At present, these furnaces in the country is still lagging behind duplication, should resolutely stop. Kiln has been built behind the need for modification or elimination. To promote the use of oxygen-enriched combustion furnace refractory technology uses air for combustion, a lot of heat was taken away in the air N2 gas, accounting for almost 30% of total calories, causing heat utilization is low, high-temperature calcination difficult and unstable. When the combustion temperature> 1300 ℃, the amount of NOX produced increases exponentially with temperature, at high temperatures, ultra-high temperature flue gas containing a high amount of NOX, increasing the difficulty of governance. Enriched combustion, oxygen-enriched air, N2 reduction due, although slightly higher than the specific heat of flue gas combustion air, but with the increase of the oxygen content, significantly reduce the amount of flue gas, the flue gas temperature rapidly. This ultra-high-temperature firing of energy saving and reduction of NOX emissions have a significant effect. Oxygen-enriched air for combustion flue gas temperature is calculated as follows: tr = Qy / CV. Qy-- low calorific value fuel, Shanxi kiln advanced equipment, kJ / kgm3; C-- flue average specific heat, kJ / m3 ℃; V-- smoke production, m3 / kg.
