Why turn to Alfa Laval for waste heat recovery?

WHR-leading-energy-savings.jpg

Leading energy savings

Alfa Laval Aalborg waste heat recovery systems provide the best overall performance in the power generation industry. They recapture the maximum amount of energy possible, which results in the shortest payback time for investment – often less than a year, depending on project specifications. Expect a 15% improvement in fuel-to-electricity efficiency in combined cycle, and/or a 95% improvement in plant efficiency in combined heat and power applications.

Profitable flexibility

Our Alfa Laval Aalborg waste heat recovery boilers enable fast ramp-up, which means you can take your power plant offline and start it up again easily. That lets you save fuel and money by using wind and other energy sources when available – with no negative impact on your waste heat recovery system’s efficiency. When your boiler systems are restarted, they quickly return to top performance, where they maximize your profits.

Envelope waste heat recovery solutions

Besides individual Alfa Laval Aalborg waste heat recovery boilers and auxiliary equipment, we can design and deliver compact, cost-saving envelope solutions for your power plant. Our envelope solutions are turnkey waste heat recovery systems, complete with boilers, integrated platforms, steel structures, piping and wires/cabling. As well as providing the equipment, we can handle the onsite installation, commissioning and service.

Why envelope solutions?

  • Resource efficiency – five times less steel needed
  • Space savings – minimized footprint
  • Easy acquisition – one-stop shop for design, installation and commissioning
  • Minimized downtime – faster and smoother installation
  • Less total CAPEX – significantly reduced investment

Engine waste heat recovery

Modern engine systems are considerably more efficient than their predecessors, but much of the fuel energy is still wasted as heat. Alfa Laval Aalborg waste heat recovery solutions maximize the energy you get from your fuel, ensuring that your power plant can use less and profit more. Their compact design is as suitable for retrofits as it is for new plants.

  • Smart technology for flexible operation – designed for frequent and quick ramp-ups
  • Effective operation with minimized capacity loss between off-service cleanings
  • Vibration- and pulsation-resistant structure

Waste heat recovery in engine power plant

Optimizing boiler response times in waste heat recovery solutions

Investing in waste heat recovery (WHR) boilers for internal combustion engines and gas turbines presents a unique opportunity that benefits operating economy as much as it does the environment. By recapturing energy and putting it to use, they reduce both fuel consumption and emissions, which lowers operating expenses. This paper focuses on the heat recovery boiler system, and how to identify start-up bottlenecks and related factors.

Gas turbine waste heat recovery

Gas turbine waste heat recovery

Gas turbine power plants are often designed for flexible operation. In both cogeneration and combined-cycle applications, the heat recovery steam generator (HRSG) must react quickly to changes in turbine load. Alfa Laval waste heat recovery systems offer rapid response that boosts your power plant’s revenue, and their layout is adaptable to new plants or retrofit needs.

  • Smart technology for flexible operation – designed for frequent and quick ramp-ups
  • Modular system design that reduces installation time and costs
  • Maintenance scheduled to match gas turbine overhauls
