Industry-leading combustion control technologies that reduce NOx, particulate matter (PM),  CO emissions at combustion facilities.

Peerless Emissions Control, consisting of Peerless and CCA Combustions Systems technologies, is a global provider of combustion control technologies to reduce NOx, particulate matter (PM), unburned carbon and CO emissions at various types of combustion facilities, including utility power plants, pulp & paper mills, chemical plants, oil refineries, ethanol plants and marine vessels.

Peerless specializes in supplying in-furnace and post-combustion emission control technologies. Our technologies have been installed in over 250 steam generators worldwide, ranging from 10 MW to 800 MW (50,000 to 5,500,000 lb./hr. steam flow), on coal, natural gas, fuel oil, refinery gas and biofuel fired units. Peerless technologies have also been installed on thermal oxidizers and dryers.

In addition to new DeNOx and combustion systems installations, Peerless Emissions Control is also a turnkey engineering and installation expert for retrofit DeNOx technologies. With expertise in complete SCR system design and optimization, CECO Peerless is your one-stop partner to meet NOx emissions regulations while working within your existing plant infrastructure. Our extensive experience with complicated SCR retrofit projects helps you get more out of your plant while avoiding unnecessary maintenance costs and outages.

The nearly 90-year history of Peerless began back in 1933 when Don A. Sillers founded the Peerless Manufacturing Company. Shortly after the company’s launch, Peerless announced the invention of the first M-Type Odorizer in 1937.

In 1988 Peerless entered the emissions control market with the launch of the SCR division and the introduction of the first SCR system in California.  Peerless Emissions Control expanded its presence in DeNox technology with the acquisitions of CCA Combustion Systems in 2014.  Peerless became part of the CECO Environmental family in 2015.

Headquartered in the United States, with additional offices in the UK, Dubai, Shanghai, and Singapore, Peerless serves customers in all time zones and locations across the globe.

Power – Fossil (Coal, Gas, Petroleum)

Fossil energy sources, including oil, coal and natural gas, are non-renewable resources that formed when prehistoric plants and animals died and were gradually buried by layers of rock. Today, fossil fuel industries drill or mine for these energy sources, burn them to produce electricity or refine them for use as fuel for heating or transportation.
