Research & Development

FBS provides an inexpensive alternative to in-house process and product development. Our CFB experts provide high quality R&D services through access to one of the world's most sophisticated fluidized bed research facilities.

Fast and confidential services make us stand out from others

Some of our past projects include:

  • Development of a mathematical model of a large CFB boiler for a major European company
  • Development of advanced CFB boilers
  • Development of novel design methodology for gasifiers
  • Development of novel equipment for torrefaction of biomass
  • Detailed heat transfer and hydrodynamic analysis of a CFB boiler at a trouble-prone plant in Asia
  • Combustion behavior of waste fuels for some Canadian companies

Design Auditing

An FBS design audit is offered to EPC contractors, plant owners and financial institutions to help protect you against failure or underperformance of fluidized bed boilers.

Although the EPC contractors take total responsibility of a power plant; ensuring that all components of the plant including the fluidized bed boilers meet their performance guarantee offered by the vendors, it has been observed that after one year of the acceptance test, more than 80% of the boilers either gave less than desired generation or had to be operated at considerably higher furnace temperature giving stiff sorbent penalty and frequent tube failures. In most cases, since these incidents occurred well after the contractual performance tests, the boiler owner could not claim compensation from the supplier. Only in limited cases these resulted in protracted legal procedures with minimal effect on the profitability of the plant.

FBS, being a specialist in CFB and BFB boiler design & operations, offers an alternative to this potential loss of revenue by acting on behalf of the plant owner; thoroughly checking the design of the boiler along every step of its design and construction to ensure that the necessary steps are taken to avoid potential future boiler failure.

  • Reduce Your Capital Cost

    • FBS will analyze the cost submitted by your vendor and determine if any superfluous costly items are included or any less expensive but better performing items could be used. FBS will also compare vendor's offer against its own cost data bank for India.

      If you are allowed to import, FBS will explore which overseas suppliers can provide you with a better price and by using FBS's extensive network in other countries will verify the technical competence and reliability of their design.

  • Save Loss of Revenue From Post Handover Downtime and Generation Shortfall

    • FBS will independently design the boiler offered by your vendor. It will compare the design offered by them and work with your vendor to alter over-design or under-design. FBS will also offer suggestions for improvements in their design to make it suitable for your specific operating conditions.

      If necessary, FBS will carry out tests with your fuel in their research unit to verify some design parameters.

  • Ensure That The tariff Calculation Gives You The Best Value

    • By using our extensive experience in power plant tariff calculation, FBS will independently calculate the tariff for given capital cost, financial package, etc. Allowing you to negotiate with your BOT vendor to get the best possible deal.

  • Choose The Right Technology

    • By taking into consideration the environmental regulation changes and availability of fuel expected for the next 20 years, FBS will help you make the best choice in boiler technology and save you from the 'least cost' choice your vendor might offer which could be very expensive a few years down the road.

  • Make The Right Management Decisions

    • Your executives can be exposed to financial, operational and technological aspects of the present day technological options for captive power plant allowing them to make informed decisions and negotiate best terms from your bidders.

What A Design Audit Can Do For You

Does FBS force boiler vendor to change their design? 

No, FBS is simply an informed advisor to the boiler purchaser. If it observes some weakness in the design or manufacturing, FBS brings that to the attention of the supplier. If convinced, the supplier could either accept that or ignore that. In that latter case the vendor takes responsibility of ignoring the technical suggestion.

Worldwide Training

Worldwide Training: In-house or at client's premises.

(Coming Soon): Web-Based Training


Fluidized Bed Systems Limited. (FBS) licensed its Circulating Fluidized Bed boiler technology to Seoul Sharp Heavy Industries in the range of 50-250 tons per hour capacity for coal, petcoke and biomass. Seoul Sharp Heavy Industries Co. Ltd. ( is a leader in the manufacture of air pollution control equipment in South Korea with a dominant presence in wet electrostatic precipitator. CFB boiler makes a strategic fit in their portfolio of environment friendly technology.

FBS is ready to license Bubbling and Circulating Fluidized Bed technology to industries who wish to diversify into the growing market of fluidized bed boiler. For further details contact: Vice President (Administration), Fluidized Bed Systems Limited at

Troubleshooting & Perfomance Analysis

Fluidized Bed Systems Limited. has a unique capability to assist Fluidized Bed Boiler operators to improve the present performance of their boilers and to investigate into the causes of boiler problems. Our personnel have more than 20 years of experience in designing and building of both Bubbling and Circulating Fluidized Bed boilers, as well as 25 years of experience and research into causes of failure of materials in fluidized bed boilers. We have especially studied the erosion process in Circulating Fluidized Bed boilers.

Some of our past projects include:

  • Agglomeration in a Bubbling Fluidized Bed boiler while operating well above design velocity.
  • Exceptionally low furnace heat absorption leading to very high back-end temprature and corrosion in a Circulating Fluidized Bed boiler.
  • Loss in generation in a Circulating Fluidized Bed boiler.
  • Frequent erosion of bed nozzles in a Bubbling Fluidized Bed boiler.

Facilities available for troubleshooting & performance analysis

FBS has access to these modern facilites:

  • SEM and XRD for analysis of materials.
  • Portable gas analyzer with on board computer for performance analysis.
  • Nozzle testing facility.
  • Bench scale Bubbling Fluidized Bed combustor/gasifier.
  • Large cold model of Circulating Fluidized Bed gasifier to study the hydrodynamics of CFB.
