Boiler Economizer Retrofit
Sergeant Bluff, Iowa
Rasmussen Mechanical Services was contracted to retrofit a boiler economizer for the Gelita plant in Sergeant Bluff, Iowa. This involved temporarily pulling the boiler stack while the economizer was attached to the boiler and then re-installing the stack.
The economizer captures energy that would normally be lost through the boiler stack and uses it to pre-heat boiler feedwater; increasing efficiency and reducing the risk of thermal shock.
“By recovering waste heat, an economizer can often reduce fuel requirements by 5% to 10% and pay for itself in less than 2 years.” – US Department of Energy
