low nitrogen natural gas boiler burner

GAS TECHNOLOGY: Boiler NOx Emissions - Plant Engineering

In many areas, industrial boiler operators face stricter regulation of NOx emissions, even with the use of clean natural gas. In some areas, operators are required to meet what are called Ultra-Low NOx (ULN) requirements, typically less than 10-12 ppm.

Natural Gas Fired Boilers - innovativecombustion.com

The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas.

LO-NOx burner - Wikipedia

It is well established that conventional "blue flame" or bunsen gas burners produce oxides of nitrogen at levels of 30-50 nanograms per joule and are as such not considered to have potential for NOx reduction. Surface combustion burners or radiant tile burners in comparison produce nitrogen oxides' levels 60-70% less.

Ultra-Low NO Burners - johnzinkhamworthy.com

n the mid-1990s, a technology was developed that allowed burning natural gas in industrial boilers while producing nitrogen oxide (NO X) emissions less than nine parts per million by volume (ppm). This tech-nology involves rapidly mixing fuel gas with air in a burner geometry that produces stable low tempera-ture combustion.
