Heat recovery steam generators (HRSG) and stack economizers can be used with industrial processes such as ovens, dryers, oxidizers, and large capacity boilers. They are typically configured to handle either horizontal or vertical gas flow, and they can be designed to precisely meet your performance, pressure-drop, and space constraints. Expense and fuel consumption can be dramatically reduced by recovering heat that would otherwise be lost to the atmosphere.


Merging long-life economizers with highly dependable evaporator, feedwater heater, and superheater technology, E-Tech engineers build custom heat recovery steam generators. HRSG units are custom-designed to meet specific plant operating requirements and steam turbine-driving needs in a single, fully assembled package.
