Pollutants emitted from combustion sources have been regulated by local and federal governments since the early 1960s. Specific rules vary by state and air district, but they generally apply to industrial, fossil fuel-fired equipment that emit nitrous oxides (NOX), carbon monoxide (CO), volatile organic compounds (VOCs), and other harmful pollutants. As a combustion source, most boilers fall into this category and are heavily regulated in some areas of the country.
These types of protocols have been implemented for the well-being of our society, and they extend not only to stationary or permanent equipment but also to boilers installed for temporary applications. A temporary rental boiler can be installed for short periods (one week) or long periods of time (multiple years) and are often required at industrial facilities for a variety of operational scenarios. These include increased process steam demand, planned maintenance outages, use during a new boiler installation, or unplanned/emergency situations.
