- Enhance environmental compliance with lower emissions and improved sustainability.
- Improve overall process performance by reusing heat to support multiple operations.
Custom-Designed Heat Recovery Configurations
Epcon offers custom heat recovery solutions designed to meet specific industrial requirements, including:
Primary Heat Exchange Systems
Primary heat recovery captures hot gas from combustion to preheat incoming process air, reducing the amount of fuel required for combustion. Epcon offers two primary heat exchanger designs:
- Recuperative Systems: Air-to-air heat exchangers using shell-and-tube configurations, achieving up to 80% heat recovery efficiency.
- Parallel Flow Heat Exchangers – Cold gas and hot gas flow in the same direction for moderate heat transfer efficiency.
- Counterflow Heat Exchangers – Opposing gas flow maximizes heat transfer efficiency and improves thermal performance.
- Series-Type Heat Exchangers – Hot gas passes through multiple tube passes to increase surface contact and heat transfer.
- Regenerative Systems: Ceramic media heat exchangers capable of up to 95% heat recovery efficiency.
- Alternating ceramic beds retain and transfer heat between process cycles, allowing for continuous preheating of incoming process air.
- Ideal for thermal oxidizer integration to maximize fuel efficiency and VOC destruction performance.
Secondary Heat Exchange Systems
Secondary heat recovery repurposes hot gas from combustion for other facility processes, including:
- Waste Heat Hot Water Heaters & Boilers – Capturing excess heat to generate hot water or steam for washers, heating systems, or production processes.
- Process Heating Systems – Redirecting hot air to support ovens, dryers, curing chambers, and industrial furnaces.
- Direct Heating Applications – Integrating heat recovery directly into air pollution control systems or drying operations for enhanced energy efficiency.
Tertiary Heat Exchange Systems
For maximum energy recovery and efficiency, tertiary heat recovery methods:
- Capture low-grade waste heat from the secondary heat exchange stage to power facility operations.
- Compress vapors, pump liquids, or drive turbines to generate on-site electricity.
- Support facility-wide comfort heating, utilizing excess thermal energy for general HVAC operations.
