Combined Cycle - Dry Low NOx Combustor
Stable Combustion, Lowers NOx Emissions
Although liquefied natural gas (LNG) is considered a clean burning fuel, Toshiba has further decreased NOx emissions in high temperature gas turbine combustion exhaust by developing a dry low-NOx combustor to restrict NOx generation at its source. Use of a method to premix combustion air and fuel evenly stabilise combustion. As a result, NOx generation is reduced to one tenth of that generated using conventional combustion methods.
Dry Low-NOx Combustor
Fuel is impinged from premix ducts installed on the outside surface of the combustor, which stabilizes the flame and reduces NOx emission. This combustor uses simplified, proven structure and fuel control process to assure high operation reliability.
NOx Emission Characteristics
Significantly lower NOx emission levels are realised when used in a wide operation zone.
Two stage Pre-mix Combustion
This combustion method minimises NOx emissions by improved flame stability, which in turn reduces the occurrence of local "hot spots" during the combustion process.
