GE Marks 'Ultra Low' NOx Gas Turbine Technology Triumph

Jul 21, 2010 · For many operators of industrial boilers, an important first step was to change from coal or oil boiler fuels to natural gas, which is cleaner burning in many respects. However, NOx continues to be a target. With natural gas, fuel based nitrogen is not the concern, but the use of air for combustion does provide the primary source for NOx.

Low-NOx Burners for Industrial Boilers | HPAC Engineering

Due to the characteristically low fuel nitrogen content of natural gas, NOx formation through the fuel NOx mechanism is insignificant. Carbon Monoxide - The rate of CO emissions from boilers depends on the efficiency of natural gas combustion. Improperly tuned boilers and boilers operating at off-design levels decrease combustion efficiency

Low-nitrogen retrofit plan for natural gas boilers, cost

Apr 01, 2021 · 1. Low nitrogen retrofit plan for natural gas boilers Gas boiler flue gas NOx is produced due to the high temperature of gas combustion, which ensures that the center temperature of the furnace flame is lowered and the formation of NOx is suppressed under the condition that the combustion status of the furnace does not change much.

Ultra-low nitrogen oxides (NOx) emissions combustion in

Jan 01, 2013 · Many ultra-low NO x gas turbine combustors have had to solve the problem of acoustic instability, and this normally involves making a change in the flame stabilizer design, so that a combustion or mixing time constant is changed. The alternative is to alter the combustor or plenum-chamber length or volume to change the acoustic constant, and this is normally much too costly.
