The temperature rise of the sulfur converter is driven by flue gas

In sulfur plants, the heating of the converter relies mainly on the heat generated by the combustion furnace. The temperature of the combustion furnace must reach over 800 degrees before the converter can start to heat up; this is due to the following two reasons: 1. At high temperatures above 800 degrees, the combustion reaction of sulfur can proceed more fully, thereby improving the operational efficiency of the system. 2. The converter can maintain good activity at higher temperatures, which is beneficial for the sulfur conversion process. If the converter is heated when the temperature of the combustion furnace is low, it may lead to the following problems: 1. The combustion reaction of sulfur cannot proceed sufficiently, reducing the operational efficiency of the facility. 2. At lower temperatures, the activity of the converter may decrease, affecting the efficiency of sulfur conversion. Regarding the gradual increase in temperature of the combustion furnace from low to high, in principle it is possible for the converter to be heated from flue gas at low temperatures generated by the furnace to flue gas at higher temperatures, but stability in device operation and the efficiency of sulfur conversion need to be taken into account. Therefore, it is generally recommended to raise the temperature of the converter after the combustion furnace reaches a certain high temperature. .
