All rights reserved.AE/ME 6766 CombustionSchool of Aerospace EngineeringImportance of Combustion Chemical energy conversion by combustion to usefulwork/heat is significant energy source ( 80% in U.S. 2019) Many applications– propulsion: ground, air, marine, space (high power density)– power generation: natural gas/coal/oil/biomass boilers, lowemissions gas turbines– heating systems: water, space heating, district heating (e.g.,GT steam plant), food processing– industrial processes: manufacture of cement, glass, paper,metal, carbon black; drying; materials/chemical processing– energetic materials: fireworks, demolition, munitions– fire safety: ignition, flame spread, smoke generation– incineration: waste, toxic materials Related technologies: fuel cells, catalytic (low T) combustionIntroduction -2Copyright 2004-2005, 2020-2021 by Jerry M.

School of Aerospace EngineeringEngineering Issues in Combustion Efficiency (chemical-thermal energy conversion)– typically high, 98-99% Environmental impacts– pollutants: NOx, SOx, CO, soot (PM2.5), UHC, – global climate: CO2, H2O, particulates (cloud formation) cleaner and sustainable fuels (syngas, biofuels, H2) Stability– static (flame stability): flame loss, blowout– dynamic: acoustic-heat release coupling, combustion dynamics Volumetric efficiency (especially for propulsion systems)– size/weight of combustor (residence time limitations) Heat loading distribution– combustor walls; heat exchange surfaces (boilers, “crackers”, ) Safety (flammability, explosions, detonations, )AE/ME 6766 CombustionIntroduction -3Copyright 2004-2005, 2020-2021 by Jerry M.
