Emission reduction through highly oxygenated viscous biofuels: Use of glycerol in a micro gas turbine

Flame characteristics of glycerol/methanol blends in a swirl-stabilised gas turbine burner

“…The physicochemical properties of crude glycerol are compared with commercial pure glycerol in Table 2. a-e refer to Refs [24][25][26][27][28] in that order while f-h refer to [6,29,30] accordingly.…”

“…6. As air flow rate increases (decreasing ER), the 70/30 methanol/glycerol flame transitions from the narrow and separated-from-nozzle flame to a broader shape showing less separation from the nozzle.…”

“…One of such alternatives that has had a universal appeal for minimizing environmental footprint of combustion are fuels with high oxygen content, particularly multifunctional alcohols and other similar biomass derivatives. These were already proven to significantly reduce the PM and NOx emissions when used in gas turbines ( [3][4][5][6]) and even atmospheric boilers [7]. Besides being main products from biomass conversion (i.e.…”

“…Under micro-gas turbine conditions, Seljak and Katrašnik [6] investigated the combustion characteristics of glycerol in regenerative cycle mode with fuel preheating.…”

Thermal calculations and NOx emission analysis of a micro gas turbine system without a recuperator

“…There is also a large body of research on NOx emissions from micro gas turbines. These include experimental and numerical simulations of the combustion and emissions of micro gas turbines fuelled by pure ammonia or methane-ammonia [11][12][13]; experimental studies of the combustion and emissions of micro gas turbines fuelled by biofuels [14][15][16]; numerical simulations of the effect of pressure and fuel-air unmixedness on NOx emissions from gas turbines [17]; experimental studies of a new combustion chamber structure to reduce NOx emissions [18]; numerical simulations and experimental studies of the emissions of micro gas turbines fuelled by syngas [19,20]; numerical simulations of the emissions of micro gas turbines fuelled by vegetable oil or vegetable oil mixtures [21,22], etc. Most of the above studies have predicted or measured NOx generation from micro gas turbines based on the specific combustion conditions in complex flow fields in combustion chambers.…”
