Combustion of Fuels and Nitrogen Oxides ( NO x

2019-10-4 · 1) note that the emission varies widely depending on application temperatures and air/fuel ratios. In general - higher combustion temperature and higher air/fuel ratios increases NO x emissions.. 2) zero emission for hydrogen is a theoretically value. In practice hydrogen burned in air produces more NO x than natural gas due to the high flame speed. 3) catalytic systems common on most modern

Module 106: Natural gas boiler flue gas recirculatio

Converting natural gas and air to heat and pollution . Air contains 21% O₂ and 78% N₂, and is supplied to the burner solely to provide the component O₂ that is required in the combustion process. Nitrogen plays no part in the combustion process of natural gas and would, ideally, pass through the boiler

» Natural Gas and the Environment NaturalGas.o

Natural gas is the cleanest of all the fossil fuels, as evidenced in the Environmental Protection Agency's data comparisons in the chart below, which is still current as of 2010. Composed primarily of methane, the main products of the combustion of natural gas are carbon dioxide and water vapor, the same compounds we exhale when we breathe

Challenges when Converting Coal-Fired Boilers to Natura

2018-2-2 · since natural gas contains no Particulate Matter (PM), the PM emissions are virtually zero other than "background" PM present in the combustion airflow or that which is swept from the boiler. Regarding NOx, natural gas contains low fuel-bound nitrogen content and requires lower excess air for combustion than coal.

Low NOx Combustion of Paraho Shale Oil in a 45 M

Combustion tests of crude Paraho shale oil (0.7 percent sulfur and 2 percent nitrogen) were conducted in a 45 MW boiler equipped with six frontface mounted burners each rated at 85 million Btu/hr. Shale oil was blended in various proportions with low sulfur oil and natural gas so that the sulfur content of the fuel did not exceed 0.5 percent.
