Boilers for Steam Power Generation

Our boiler technology has existed for more than 100 years, and our boilers make up about 30% of all boilers installed or under construction in power plants worldwide.

Unparalleled Fuel Expertise

Our knowledge of fuels and combustion, a core GE competence, comes from our extensive laboratory and field experience. GE technologies help our customers to burn a wide spectrum of fuels—from high-rank coals to low-rank coal wastes, and from oil and natural gas to opportunity fuels such as petroleum coke, biomass, and oil shale. Additionally, our excellent fuel firing flexibility can lower the cost of electricity for our customers.

Tangential Firing System

GE introduced the tangential firing system in 1927. We inject fuel and air through windboxes from the corners of the furnace, aimed tangent to an imaginary circle in the center of the furnace. This creates a single rotating flame envelope (vortex) that produces a uniform and consistent heat profile across the furnace walls over the operating load range. Due to aerodynamics, the fuel and air are mixed throughout the furnace, resulting in high efficiency combustion. For our two-pass and tower boiler designs, tangential firing also provides:

 

  • Low primary NOx emissions for decreased SCR catalyst volume, reagent use, and maintenance requirements
  • Efficient use of furnace volume, resulting in reduced slagging tendency and soot-blowing frequency
  • Excellent flame stability for increased unit turndown and a wider latitude for fuel property variation
  • Tilting capability resulting in no attemperation for reheat temperature controls

Industry Leader in Supercritical and High Efficiency

GE led the industry in developing supercritical steam generation technology, and is an industry leader in today’s high efficiency ultra-supercritical PC and CFB technology

High Efficiency

GE’s ultra-supercritical boilers contribute to cycle efficiencies of 42 to 45% on an HHV basis (44 to 47% LHV basis). This significantly reduces both fuel and emission control costs for our customers.

Extensive Experience and Reference 

To date, GE has directly supplied more than 116,000 MW of supercritical/ultra-supercritical boilers worldwide, and has licensed and trained other companies to install an additional 140,000 MW. 

Ongoing Development

We continue to invest significantly in research and development dedicated to improving our high efficiency power generation equipment.
