| Comprehensive Pros and Cons | Low over/under-burn rate, high lime reactivity, low energy consumption. Cons: High investment cost, complex maintenance. Optimal production for 600T/D is only 500T/D when using low-calorific-value blast furnace gas. | Low over/under-burn rate, high lime reactivity, low energy consumption. Cons: High investment cost, complex arch and heat exchange duct prone to issues, complex maintenance. | Lower investment, simple refractory and brick structure, low gas pressure required. Cons: High energy consumption, higher investment cost, prone to issues with combustion beam, higher staffing needs, complex maintenance. | Low investment cost, simple refractory and brick structure, low gas pressure required, fewer staff needed, high adaptability. Cons: Slightly higher energy consumption, higher over/under-burn rate. | Comprehensive consideration of investment and operating costs, operational management requirements, environmental policies, investment, and project risks to determine the core process route. |
