Which fuel is good for using in lime kiln to burn lime
The selection of fuel is crucial in the process of firing lime in a lime kiln, as it directly affects production efficiency, cost, and environmental effectiveness. Common fuels include solid fuels (such as anthracite and coke), gas fuels (such as natural gas, blast furnace gas, coke oven gas), and liquid fuels (such as heavy oil).
Anthracite is widely used in solid fuels due to its high fixed carbon content and stable combustion, but attention should be paid to the pollutants it may produce. Coke has high calorific value and low ash content, making it suitable for occasions with high requirements for lime quality, but it also has high cost and pollution problems.
In terms of gas fuel, natural gas has gradually become the preferred choice due to its clean and efficient characteristics. It produces fewer pollutants during combustion, which is beneficial for environmental protection. Blast furnace gas and coke oven gas, as by-products of the steel industry, have lower costs but complex compositions that require pre-treatment.
Liquid fuels such as heavy oil have high calorific value but are expensive, and they emit a significant amount of pollutants during combustion.
Considering all factors, natural gas is the ideal choice for pursuing environmental protection and efficiency; If cost is prioritized and environmental requirements are moderate, anthracite or coke is more suitable; By utilizing industrial by-products such as blast furnace gas, resource recycling can be achieved while reducing costs. Enterprises should choose the most suitable fuel based on their own production conditions, environmental requirements, and economic strength.
