Overview

Demonstrates improved combustion and spray characteristics in heavy-duty gas turbines using nanobubble diesel fuels, suggesting higher efficiency.

Key Points

  • The research investigates the impact of nanobubble-enhanced diesel fuels on diesel spray and combustion behavior in gas turbines.
  • Prepared different nanobubble-enhanced diesel fuels with air and methane.
  • Analyzed spray characteristics such as spray cone angle and SMD using pressure swirl nozzles.
  • Conducted combustion tests to evaluate emission outputs and temperature uniformity.
  • Nanobubble-enhanced fuels reduced SMD by 14% and increased spray cone angle by 3.9%.
  • Air bubbles reduced NO x emissions by up to 14%, while methane bubbles increased them by up to 13%.
  • Both bubble types showed reduced CO emissions and impacted outlet temperature distribution.
