Circulating Fluidised Bed Boiler Technology

Doosan Lentjes provides Circulating Fluidised Bed (CFB) boiler technology, which ensures that fuel quality and range is maintained throughout client projects.

Constant refinement and innovation means you benefit from a product which can deliver the critical reliability and environmental performance you need.

CFB technology is a part of our heritage and, as a trusted name in the deployment of high-efficiency boilers with integrated Fluidised Bed Heat Exchanger (FBHE) systems, we have a proven track record of up to almost 300MWe (~700MWth) with the capability to offer designs up to 500MWe (~1300MWth).

Our focus on constant refinement and innovation in our products has allowed us to develop a design that is more compact and minimises boiler footprint.  Coupled with our parametric design process, we can offer superlative value regardless of your application.

At the heart of cleaner, highly efficient power generation at your facility, our proven CFB process delivers ‘best in class’ emissions performance. Utilising limestone furnace addition ensures that more than 90% of sulphur dioxide (SO2) emissions are captured and thanks to low, multi-stage combustion at temperatures of 850°C, we minimise thermal NOx formation and deliver remarkable NOx emission performance.

Our CFBs provide a range of further benefits:

  • Product applications for a wide range of solid and liquid fuels including coals, lignites, biomasses, refinery by-products, slurries, etc
  • Carbon burn-out of 98-99% depending on fuel type
  • Partial load operation as low as 40%, with a rate of load change of up to 3-7% per minute dependent upon your needs
  • Optimised for conventional sub-critical steam, supercritical and Combined Heat and Power (CHP) applications

We continue to deliver a range of innovations to maximise availability, reliability, efficiency and minimise emissions. Our integrated Fluidised Bed Heat Exchanger (FBHE) is just one of our key innovations delivering more effective heat transfer from hot ash to steam allowing for the optimal operating conditions that result in high efficiency.  Coupled with our Spiess valve technology for reliable ash flow control such innovations also bring enhanced availability.

Our developments continue to focus on improving value with performance be that through water-cooled cyclones with compact geometries to developing the next generation CFB at higher supercritical steam conditions.

With over 100 CFB plants in operation globally our clients have placed their trust in Doosan Lentjes to continue to deliver product improvements that add value to their power generation and steam production CFB.
