GE originally introduced the tower boiler design in the mid-20th century to utilize high moisture lignite in Europe. With standardization and modularization, tower boiler equipment can be sourced and constructed cost-effectively around the globe while meeting high quality standards.

High cycle efficiency

Boiler towers achieve high cycle efficiencies at ultra-supercritical conditions reaching 44 to 47% on an LHV basis (42 to 45% HHV basis), leading to less fuel consumption and reduced emissions.

Low primary NOx emissions

Low primary NOx emissions using advanced tangential firing systems and effective overfire air arrangements, resulting in less SCR catalyst material and less reagent consumption.

Outstanding operational flexibility to support a stable grid

Reliable plant operation enhanced by tower boiler with fully drainable heating surfaces, resulting in faster startup periods and reduced stresses in pressure parts.
