Gas Conversion and Low NOx Retrofit of a 450 kpph Tangentially Fired Boiler A North American utility company needed to convert a tilting tangential oil‐fired boiler to a dual fuel (natural gas and oil) unit. Additionally, heavy oil NOx emissions were to be reduced from the current low NOx burner levels.

Numerical study on NOx reduction in a large-scale heavy

A numerical approach is given to study the combustion of heavy-fuel-oil in boilers. • The model is validated against a benchmark test and the on-site operational data. • Effect of burners' adjustments on NO emission and combustion efficiency is studied. • Air distribution in burners' stages and swirl intensity greatly affect NO

1.3 Fuel Oil Combustion

Fuel nitrogen conversion is the more important NOx-forming mechanism in residual oil boilers. It can account for 50 percent of the total NOx emissions from residual oil firing. The percent conversion of fuel nitrogen to NOx varies greatly, however; typically from 20 to 90 percent of nitrogen in oil is converted to NOx. Except in certain large

The purpose of the evaluation was to assess the capabilities of SNCR technology to reduce NOx emissions on large boilers. The two pulverized coal-fired units evaluated were: a 500 MW wall-fired boiler equipped with low-NOx burners and overfire air and an 880 MW tangentially fired boiler equipped with a low NOx concentric firing system which

Boilers and Process Heaters - sdapcd.org

Boilers can operate on a variety of fuels including natural gas, propane or fuel oil. Boilers can be used to produce hot water or steam. Process heaters are used to heat a working fluid other than water where flue gas does not come into contact with the working fluid. Common techniques for controlling emissions include the use of low NOx

CFD Simulation of a Low NOx Oil Fired Boiler | GT | ASME

Nov 11, 2008 · This paper compares the results of an advanced CFD calculation with measurements of a heavy fuel oil fired low NOx boiler. First, a state of the art boiler was investigated and the impact of boiler load and excess air on the NOx emissions was measured. In a second test run a staged combustion technology was integrated using the over fire air
