Engine, Boiler & Combustion Source Testing

Onterris helps facilities measure and document emissions from regulated combustion equipment so compliance teams, operators and engineers can make decisions with defensible data.

• Permit-required testing for boilers, engines, heaters and turbines
• Emissions measurement for flares, incinerators and process combustion systems
• Source testing to support compliance demonstrations and operating decisions
• Field execution for routine tests and complex stack testing programs

Our specialists measure key combustion-related pollutants using applicable regulatory methods to support accurate reporting and defensible compliance data.

• Nitrogen oxides (NOx)
• Carbon monoxide (CO)
• Sulfur dioxide (SO2)
• Particulate matter (PM)
• Volatile organic compounds (VOCs)
• Ammonia (NH3)

Our teams help clients understand how combustion performance, control equipment and operating conditions affect emissions so they can make informed decisions about compliance and performance.

• Combustion efficiency evaluation
• Burner and boiler performance assessment
• SCR and SNCR optimization support
• Ammonia injection balancing where applicable
• Complex gas matrix analysis

We support testing programs that evaluate how control systems perform during operation and changing conditions.

• Control equipment efficiency testing
• Capture efficiency and destruction efficiency testing
• Operating condition review
• Performance data to support optimization

We support routine and complex source testing programs from initial planning through final reporting so clients can meet local, state and federal requirements with confidence.

• Permit review and test planning
• Dedicated project manager for scope, schedule and logistics coordination
• Regulatory reporting support
• In-house laboratory analysis for reliable data quality
