FAQs of WASTE HEAT RECOVERY UNIT:
Q: How does a Waste Heat Recovery Unit with a shell and tube or plate-type heat exchanger work?
A: A Waste Heat Recovery Unit (WHRU) utilizes either a shell and tube or plate-type heat exchanger to transfer heat from hot exhaust gases to another fluid, typically water or air. The system captures waste heat from industrial processes, allowing it to be reused for heating or energy generation, thereby improving overall energy efficiency and reducing operational costs.
Q: What are the installation options for this WHRU, and where can it be deployed?
A: The WHRU is available in both skid-mounted and modular formats, making it suitable for easy integration into existing or new industrial facilities. Its flexible installation, combined with floor-mounted design, allows for deployment in a wide range of industries such as manufacturing plants, power stations, or chemical processing facilities across India and worldwide.
Q: When should a facility consider installing a Waste Heat Recovery Unit?
A: A facility should consider installing a WHRU when there is significant waste heat generated from processes like flue gas exhaust or industrial furnaces. Installing the unit becomes particularly valuable when energy costs are high, there is a drive for sustainability, or regulatory compliance requires efficient heat management and emission reduction.
Q: What are the primary benefits of using this energy recovery system?
A: The main benefits include enhanced energy efficiency, reduced fuel consumption, lower greenhouse gas emissions, and cost savings. The WHRUs high thermal efficiency (7895%) enables facilities to reclaim energy that would otherwise be lost, supporting both operational and environmental objectives.
Q: How is the WHRU maintained and what is its expected operating life?
A: Designed for low maintenance, the WHRU features robust construction with quality insulation and corrosion protection. Routine checks of temperature and pressure sensors, along with periodic inspection of heat exchange surfaces and the skid framework, help ensure reliable performance. These units are manufactured for long-term use under rigorous industrial conditions.
Q: In what process conditions can this WHRU operate effectively?
A: This WHRU handles gas inlet/outlet diameters from 200800 mm, operates at pressures of 0.11.6 MPa, and can function in temperatures up to 420C. Its design accommodates air flows from 5,00030,000 m/h and capacities from 1,000 to 50,000 Nm/hr, making it ideal for continuous processing environments.
Q: What control and monitoring features does the WHRU offer?
A: The WHRU includes an integrated control panel (digital or analog) with automation options (semi-automatic/automatic). It is equipped with temperature and pressure sensors (thermocouple or RTD) for precise inlet/outlet monitoring, enabling reliable and safe operation as well as straightforward performance tracking.
