Hualing Henggang Comprehensive Utilization Project of Blast Furnace Gas
2017-11-06 | 3943 Posted by: admin 2017-11-06 | 3943

Before the blast furnace gas purification CO plant was put into operation, the blast furnace gas utilization method adopted by Henggang was to mix some natural gas into the blast furnace gas to increase its heating value for use in the rolling furnace. After the project was launched, Henggang purified the 67000Nm3 / h blast furnace gas to obtain 17,500Nm3 / h of CO product gas and directly delivered it to the heating furnace. The purity exceeded 70% and the calorific value reached 8800kJ / Nm3. According to reasonable calculations, it can replace natural gas 3382 × 104Nm3 per year It is equivalent to 38,000 tons of standard coal, which is equivalent to 1/4 of Henggang's original natural gas consumption, which has largely alleviated Henggang's tight demand for natural gas.
