Calcined lime kiln fuel gas used in more varieties, commonly used gaseous fuels coke oven gas, converter gas, blast furnace gas, calcium carbide furnace gas, natural gas and gas prepared by the mixed gas and so on. Calcined lime on fuel gas requirements are as follows. 1, the heating value of the other conditions are the same, the gas can reach the combustion flame temperature depends on the heating value of the gas. In the kiln, the gas reaches the combustion flame temperature should be higher than the lime calcination temperature difference between the two is as follows: Rotary: not low D 100 to 150 ℃. Maintaining a large temperature difference between the temperature of the kiln lime calcination and speed regulation is advantageous. 2, the yield of different gas heating value gas, under the same combustion conditions, the low heating value per unit volume of the gas meter is not identical. Low calorific value gas higher heating value than the higher yield smoke gas, fuel consumption in a rotary kiln under the same conditions, to produce more gas, easily filled kiln space conducive to uniform heating of lime. However, the amount of more smoke exhaust system will load increases, investment in equipment and operating costs. Replacing the existing fuel system, exhaust system should pay attention to the ability to be accounted for. 3, the flame blackness blackness characterization flame flames heat radiation capability. The three atoms in the gas flue Hugh (H2O, CO2) content is, the higher the flame blackness. In the rotary kiln, the material and lining brick flame and heat exchange rely mainly on thermal radiation, so the blackness of the flame for heating the material has outstanding significance.
