Surface Combustion with Thermal Evaporation
Surface combustion technology solves traditional heat exchanger failures common with other designs.
These designs are subject to application-specific conditions that impact the performance and life expectancy of the heat exchanger.
The Wastewater Evaporators design utilizes a surface combustion technology in which premixed gas and air burn on a porous medium surface layer.
- Surface combustion technology benefits include:
- Extremely low emissions of NOx, CO, and unburned fuel components
- No risk of heat exchanger metal impingement or high heat stress
By contrast, the double pass tubular design has flame and combustion gasses drawn by an induced draft blower through the heat exchanger.
This design has sweep elbows, and a 90-degree pipe turns the burner flame contacts. This risks thermal damage to these welded areas compounded with application solids and grime buildup. If solids accumulate on the heat exchanger's flat top oily residues, thermal damage will likely occur.
The top of the heat exchange is sloped to prevent solids from accumulating. The vertical water tubes are easily accessible from the top of the tank for periodic inspection and cleaning. All heat exchangers are not created equal. The Wastewater Evaporators design combines innovation with high quality, thus producing a robust solution to problematic evaporator applications.
