HEAT RECOVERY SYSTEM
Did you know that Devco Process Heaters (DPH) offers a Heat Recovery and Improvement Maintenance (HRIM) program, that has been available for our customers since 2014?
The HRIM program provides a means to improve your current heating systems operation with minimal cash infusion for major new equipment investments. With the current market, lower oil prices, and COVID-19’s impact, DPH’s HRIM program is ideal to accommodate today’s requirements to extend the life and performance of your heater.
DPH’s Field Service Expert (FSE) will travel to your site at your convenience and collect the necessary data to provide a complete comprehensive summary of your existing heating systems condition with potential improvements addressing the following as a minimum:
- Mechanical Evaluation
- Inspect and confirm existing condition
- If required provide quotation to repair, recover, and improve mechanical operation.
- BMS Evaluation
- Inspect and confirm compliance with original BMS certification
- If required provide quotation to recover and meet existing BMS requirements
- Provide quotation for current state of the art BMS standards and components.
- Upgrade existing BMS to improve or increase DCS interface and communication.
- Combustion System Evaluation
- Inspect to insure proper operation and condition.
- If required provide quotation to replace damaged components.
- Provide quotation to improve:
- Burner performance
- Combustion air blower performance
- Combustion efficiency
- Emission control
- Increase heating system overall thermal efficiency
- Provide equipment to improve the overall heating system efficiency (e.g. Economizer/Convection Section or Air Preheat).
Please feel free to contact me for more information or to schedule one of our FSE’s to start the
HRIM process.
Looking forward to hearing from you, stay safe and healthy!
Waste Heat Recovery
A HEAT EXCHANGER WHICH INCREASES THERMAL EFFICIENCY
In these times of increasing costs and greater interest in energy conservation, Devco has developed a new product which converts otherwise waste heat to a useful purpose. The Devco Waste Heat Recovery System (WHRS) takes advantage of available heat in flue gas products that would otherwise be released into the atmosphere. The Devco WHRS will transfer this available heat to a variety of media ranging from natural gas to crude oil.
Less heat transfer area is required in the Devco WHRS than conventional heat exchangers. This is due to the high velocity experienced on the shell side of the exchanger. With high transfer rates and less tubing, lower pressure drops are realized. The heat exchanger coil bundle can be designed to any applicable code with working pressure up to 9,000 PSIG.
In the event of process flow cessation, control of the heating medium temperature virtually eliminates damage to the coil bundle and process fluid.
The utilization of a Devco WHRS will increased the thermal efficiency of existing or new systems.
COMPLETE CONTROLS DELIVER SAFE UNATTENDED OPERATIONS
Control Systems for the Devco WHRS deliver maximum performance at relatively low operating temperatures. This allows unattended operations on even the most sensitive process fluids.
The amount of flue gas circulated and bypassed is controlled by monitoring the process fluid outlet temperature.
True countercurrent and concurrent heat exchange is utilized. The Devco WHRS is designed to keep flue gas temperature above its dew point. This feature virtually eliminates corrosion and oxidation of the finned tubes in the heat exchanger.
SUITED FOR SENSITIVE HEATING APPLICATIONS
The Devco WHRS non-radiant convection design makes the system ideally suited for a wide range of sensitive heating media. The Devco WHRS can be used to:
- Heat Pipeline Oil, Crude Oil, Oil-Water Emulsions, and Heat Transfer Media
- Generate Steam
- Heat Natural Gas
- Regenerate Glycol or Amines
- Heat Sensitive Fluids and Gases to High Temperatures
PROGRAMMED DESIGN SELECTIONS FOR ECONOMY
The Devco WHRS design and calculations are completely computerized. Material and heat balances are calculated on both shell and tube sides of the exchanger. Convection heat transfer rates for thermal design and mechanical ratings are utilized in the heat exchanger design.
VARIETY OF APPLICATIONS
The Devco WHRS can be designed to fit any specific need, to take advantage of the waste heat only when it is available. The Devco WHRS is ideally suited in applications where there is a critical need to maintain a constant heat load being transferred to the process fluid.
Devco can incorporate in its design:
- An auxiliary burner system which operates simultaneously while the waste heat flue products are flowing thru the Devco WHRS. This burner system operates automatically to provide a constant total heat load when the available waste heat fluctuates.
- A standby heater to provide the required heat load during seasonal periods when the available waste heat is minimal or non existent.
CONSIDER THESE ADVANTAGES
Increased Operating Efficiencies
The Devco Waste Heat Recovery System will increase the thermal efficiency of a new or existing system.
Accurate Control System
Process fluid degradation and scaling are minimized.
Finned Process Pipe
Small tube bundles permit minimum pressure drop. Each process tube is accessible for replacement.
Low Installation Cost
The Devco Waste Heat Recovery System modules are designed for simple, economical installation and relocation.
No Operational Costs
The Devco Waste Heat Recovery System takes advantage of available waste heat. Therefore, operational costs are minimal to none.
Continuous Rapid Circulation of Hot Inert Gases
Uniform flux density in heat exchanger section is assured. Hot spots are avoided. Heating of sensitive fluids can be predicted and controlled.
