Webhydrogen can lead to the thermal formation of nitrogen oxides (NO x – the sum of NO + NO 2) via a mechanism that also applies to the combustion of fossil fuels. NO 2 is a key air pollutant that is harmful in its own right and is a precursor to other pollutants of concern such as fine particulate matter and ozone. Minimising NO Abstract. Nitrogen dioxide is a notable workplace contaminant in many types of underground mines, both due to its production in fossil fuel combustion and blasting, as well as for its human health effects. In some jurisdictions, permissible limits have reduced by over 90%. Although it is recognized that … Ver mais Hatch was recently presented with a challenge during the detailed ventilation design of an underground Canadian mine: to meet the strict … Ver mais Following the development of the diesel engine performance requirements, Hatch consulted with engine manufacturers to analyze engine data and determine compliance with the … Ver mais Hatch developed a diesel engine specification for the project to define the specific performance required to meet the desired NO2 limit. An important aspect of the specification was to highlight that an engine being Tier 4 … Ver mais Technologies associated with Tier 4 Final (EU Stage IV) engines, such as SCR, provide many advantages in underground mining applications. Firstly, as discussed in previous sections, … Ver mais
