Guideline A-9: NOx Emissions from Boilers and Heaters

The purpose of this Policy Guideline is to reduce smog in Ontario, by reducing the emission of oxides of nitrogen by new (or modified), large, boilers and heaters. This guideline specifies limits for emissions of oxides of nitrogen (NOx") for new or modified fossil-fuel boilers and heaters which have a fuel energy input greater than 10 million Btu/h (10.5 GJ/h).
