Client approached Furnace Improvements to provide a design for replacing the convection section of the CO Boiler. Furnace Improvements carried out the engineering study for replacing the convection section. We conducted a detailed operation analysis of the existing CO heater and built a model of the existing design. With the model built, we were able to simulate the current operating conditions and predict the heater performance for the future operating conditions.
We developed a better design overcoming the drawbacks in the existing CO Heaters. The convection section was redesigned to:
The new design was developed retaining the existing soot blower locations and platform elevations, and without any additional firing requirement. The detailed engineering drawings of the convection section vendor were also reviewed.
The proposed revamp took care of all the issues with the existing CO Boiler. It was estimated to save the client almost $550,000 per year. The heater was commissioned in March 2003 and has been running continuously now.
