Double-hearth lime kiln
The invention discloses a double-hearth lime kiln which comprises a double-hearth furnace body, a fuel assembly, a waste gas emission assembly, an oxygen enrichment assembly and a PLC. The oxygen enrichment assembly is connected with the double-hearth furnace body through a pipeline. The PLC adjusts the oxygen content in the double-hearth furnace body through the oxygen enrichment assembly. Therefore, the oxygen content in the double-hearth furnace body can be adjusted, the application of the low-calorific-value coal gas to the double-hearth lime kiln can be realized, the requirement of the double-hearth lime kiln on the fuel calorific value is reduced, the utilization rate of the low-calorific-value coal gas of an iron and steel plant is improved, the emission of the low-calorific-value coal gas of the iron and steel plant is reduced, and the production unit use cost.
本发明公开了一种双膛石灰窑，其包括双膛炉体、燃料组件、废气排放组件、富氧组件和PLC控制器，所述富氧组件通过管路连接所述双膛炉体，所述PLC控制器通过所述富氧组件调节所述双膛炉体内的含氧量，从而可以调节所述双膛炉体内的氧气含量，从而可以实现低热值煤气在双膛石灰窑上的应用，降低双膛石灰窑对燃料热值的要求，提高钢铁厂对低热值煤气利用率，减少钢铁厂低热值煤气排放，降低生产单位使用成本。
