Recently, the Yangzi Petrochemical Refinery used plant shutdown to carry out technological transformation, and recycled low-pressure steam to heat up the fuel gas, which increased the fuel gas from approximately 20°C to 80°C to 100°C. It has both recycled low-pressure steam and increased The utilization of fuel gas components reduces the consumption of fuel gas and improves the thermal efficiency of the heating furnace. It is reported that since July, the thermal efficiency of heating furnaces has remained above 92%, an increase of 2% year-on-year.
