CCA SYSTEMS
COMBUSTION SYSTEMS aND LOW-NOx BURNERS
Peerless Emissions Management engineers high-efficiency, low-emission combustion systems for industrial and utility boilers. Built on the proprietary technology of CCA Combustion Systems, Peerless low-NOx burners stabilize the combustion process, so units operate safely throughout the load range, with high turndown, low NOx and CO emissions and ease of maintenance.
PEERLESS EMISSIONS
One Partner. Inlet Combustion to Outlet Emissions.
Peerless and CCA Combustion Systems
CCA’s combustion expertise is part of Peerless Emissions Management. CCA Combustion Systems, was founded in 1980 and acquired by Peerless in 2014, expanding its technology beyond post-combustion emissions control. Peerless joined CECO Environmental in 2015, as a global industry leader in the engineering, design, development, testing and manufacturing of high-efficiency, low-emission combustion and emissions systems for industrial and utility boilers.
CCA technologies have been installed on hundreds of steam generators worldwide, ranging in size from 10 MW (25,000 lb/hr steam generation) to 800 MW, and on thermal oxidizers and dryers.
Low-NOx Burners (LNB)
Peerless low-NOx burners are configured to stabilize the combustion process and allow the unit to operate safely throughout the load range. Each burner is engineered to provide stable combustion with high turndown, low NOx and CO and ease of maintenance.
LNB Benefits
- Low total cost of ownership
- High-efficiency NOx reduction of up to 50%
- Extends burner life
- Reduces fly ash carbon losses and loss on ignition (LOI)
- Lowers excess air levels and maintains the lowest possible emissions at maximum and minimum loads
LNB Applications
- Utility power boilers, wall-fired and T-fired
- Package boilers
- Recovery boilers, startup and auxiliary fuel burners
- Burner heat capacity from 25 MMBtu/hr to 300+ MMBtu/hr
Fuel Flexibility
Peerless low-NOx burners are designed to fire any combustible gaseous or liquid fuel, from natural gas and hydrogen to process off-gases, hazardous waste streams, ultra heavy fuel oils and biomass. This fuel range sets Peerless apart, giving facilities one combustion partner for the fuels their process requires or produces.
Fuels We Fire
- Natural gas, refinery gases, propane, hydrogen and landfill or digester gases
- Process off-gases and liquids
- Hazardous waste gases and liquids
- Heavy fuel oil
- Ultra heavy fuel oils (pitch and bitumen)
- Light fuel oils and kerosene
- Biomass, including wood and nut shells

Combustion and Emissions Control in One Project
Meeting a NOx limit starts at the burner and ends at the stack. Peerless handles both ends. Peerless engineers design and supply the burners and combustion systems at the inlet, then engineer the SCR or SNCR system that controls emissions at the outlet. Peerless brings combustion and emissions control together under one project and one partner.
At a New England paper mill, Peerless installed an SCR system into the existing system, optimized the combustion system and converted the plant to a safe urea reagent system. The retrofit achieved ultra-low emissions across the mill’s full range of production while improving plant operations at wider load ranges.
COMBUSTION SYSTEMS
Complete Combustion Solutions Suite
Alongside low-NOx burners, Peerless combustion solutions include overfire air (OFA), flue gas recirculation (FGR), combustion tempering (CT) and rich reagent injection (RRI) systems, together with SNCR and SCR systems for post-combustion NOx control. These combustion control technologies reduce NOx, particulate matter (PM), unburned carbon and CO emissions.

Keep Your Burners Performing
Peerless supports combustion systems long after start-up with replacement parts, combustion optimization services, systems support, on-site technical advisory engineers and long-term service agreements.
Retrofits Delivering Measurable Results
Lower Emissions. Greater Operating Flexibility.
At Tucson Electric Power’s Sundt Generating Station Unit 4, Peerless replaced nine burners with CCA low-NOx gas burners designed to directly replace the existing burners. Tested at 165 MWg, NOx dropped from a baseline of 0.230 lb/MMBtu to 0.162 lb/MMBtu and CO dropped from 0.062 lb/MMBtu to 0.009 lb/MMBtu. The new burners deliver reliable, repeatable light-off without operator adjustments and a stable flame with 10:1 turndown, allowing maximum boiler turndown with all burners in service.
