Combustion Systems

Advanced biogas utilization, thermal oxidation, and energy recovery systems for environmental compliance and resource efficiency

Overview

What is Combustion Systems?

Combustion systems provide essential solutions for biogas utilization, volatile organic compound (VOC) destruction, and thermal energy recovery in wastewater treatment and industrial facilities. These systems safely convert gaseous byproducts and emissions into useful energy while ensuring environmental compliance through complete, clean combustion.

Applications range from biogas flares that safely dispose of excess anaerobic digester gas, to combined heat and power (CHP) systems that convert biogas into electricity and thermal energy. Thermal oxidizers destroy VOCs and odorous compounds from treatment processes. Boilers and furnaces utilize biogas as renewable fuel, displacing fossil fuels and reducing operating costs.

Spans Envirotech designs and supplies comprehensive combustion solutions including enclosed flares, dual-fuel engines, gas turbines, thermal oxidizers, and biogas boilers. Our systems incorporate advanced controls, safety interlocks, and emissions monitoring to ensure reliable, efficient, and compliant operation while maximizing energy recovery value.

Process

Combustion Technologies

1

Biogas Collection & Conditioning

Biogas from anaerobic digesters is collected, filtered to remove moisture and contaminants, and pressurized for delivery to combustion equipment.

2

Combustion Air Management

Controlled air supply ensures complete combustion with minimal emissions. Variable speed blowers adjust air-fuel ratios based on gas composition and heating value.

3

Ignition & Flame Control

Automatic ignition systems start combustion safely. Flame monitoring ensures continuous operation. Advanced controls maintain optimal combustion temperature and residence time.

4

Energy Recovery

Heat exchangers recover thermal energy from flue gases for process heating, space conditioning, or power generation. CHP systems convert biogas chemical energy into electricity and heat.

5

Emissions Control

Complete combustion destroys VOCs and odorous compounds. Emissions monitoring verifies compliance. Selective catalytic reduction (SCR) controls NOx when required.
