3.1.2 SoLoNOx Combustion System (Optional)
In addition to the conventional combustion system, Solar’s proprietary SoLoNOx dry
emissions system reduces pollution by limiting the formation of nitrous oxides (NOx),
carbon monoxide (CO), and unburned hydrocarbons (UHC). This system uses lean
premix combustion to lower the maximum flame temperature and reduce pollution
formation. Solar’s engineering staff works with customer’s to meet local permitting
emission requirements.
