Combustion of Fuels and Nitrogen Oxides ( NO x ) Emission

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 than natural gas due to the high flame speed. 3) catalytic systems common on most modern ...
