How to reduce the consumption of natural gas in heating furnaces
Thread Content
To reduce the consumption of natural gas in the heating furnace while keeping the processing load unchanged in the hydrogenation unit, what measures should be taken? Our operating pressure is 3 Mpa.
Maintain an oxygen content of less than 4% and a flue gas temperature slightly above the dew point corrosion temperature; from a process perspective, this can be achieved by raising the temperature of the material fed into the furnace as well as the temperature of the fuel gas feed. The key is to strengthen the adjustment of the \"three valves and one plate\" on-site
There are many ways to save fuel in heating furnaces: reducing the flue gas temperature, increasing the feed temperature of the furnace, using efficient burners, controlling the temperature of the combustion air, cleaning the convection chamber, adjusting the amount of combustion air and the oxygen content, as well as regulating the wall temperature of the furnace.
1. The fuel line is equipped with sequential control for temperature and flow regulation. . . Avoid instability in fuel gas regulation. . . 2. Monitor the oxygen content in the flue gas. . . Assess the combustion effect. . . Adjust the dampers in a timely manner. . . :lol 3. Use high-efficiency burners designed specifically for gas. . .
