The Benefits of CFB Technology for Utility Power

Sumitomo+SHI+FW_Logo (main).jpg

Topics presented in the webinar will include:

  • 2,200 MWe Samcheok Green Power Plant in Korea utilizing SFW's most advanced ultra-supercritical CFB technology firing coals and biomass

  • 460 MWe Lagisza Supercritical CFB Plant in Poland

  • 1,000 MWe Mong Dong plant in Vietnam firing high ash Vietnamese anthracite

  • 600 MWe Cleco plant in the USA firing coals and petcokes

  • 510 MWe Soma Kolin plant  in Turkey  firing Turkish lignite

  • 105 MWe Dangjin plant in Korea firing biomass and demo woods

An important added benefit is CFB’s clean burning process which can avoid expensive air pollution control equipment. This allows CFB plants to reach levels of emissions, reliability, plant capital and operating cost well beyond today’s fleet of pulverized coal (PC) power plants. For consumers, this means reliable, clean power at the lowest possible cost. This free webinar can help you make an informed decision about the application of CFB technology in your power market and on your specific fuels.

In this informative webinar, Kris Matsuo, Director, Sales and Business Development, Asia, Strategic Business Development, Sumitomo FW (SFW), will discuss the technical, economic and environmental benefits of CFB boilers applied to the Asian power market. Plant case studies that illustrate the fuel flexibility of the CFB on fuels commonly available in Asia will be presented

Below are some of the questions discussed during the webinar:

  • What are the in-furnace NOx emission levels that can be achieved in CFB boilers without post-combustion SCR application?

  • What cleaning technology is offered for biomass-fired applications: steam, air, or sonic horn? Which is more suitable for convection pass cleaning?

  • Can we achieve 30 ppm SOx in a CFB boiler?

  • What is the average percentage base load a CFBC can be operated continuously?

  • What is the tube life in the kick-out area in your supplied CFB boilers around the world?

  • Do you have any experience with refractory anchor damage in your supplied CFB boilers?

  • Is it okay to use higher moisture coal (45%) in a CFBC? What are the precautions for safe and continuous operation?

  • How does a CFB boiler manage low ash fuels, like below 7%?

  • How can we adjust the refractory height in the kick-out area to reduce the high erosion rate on the lower furnace side?

  • Is there any case where HFO is used without FGD/SCR?

  • Why does the refractory dislodge in the inlet duct of the hot cyclone, and how can this be avoided?

  • Do any of SFW's CFB installations have wet/dry FGD/SCRs?

  • Do your FW boilers face agglomeration issues in the cyclone? Please explain and how to mitigate this.

  • Lots of refractory in the furnace, separators, and COD restricts too fast cold start-up. How does start-up time compare with PC?

  • What is the cold, warm, and hot start-up time of these boilers and also the shutdown time to make entry into the furnace for maintenance?

  • To stop agglomeration or slagging, do you need to inject coal ash into the furnace or increase sulfur content in the flue gas?

  • For petcoke-fired CFB, what is the final normal disposition of limestone, especially when the sulfur of petcoke exceeds 7 wt% sulfur?

  • Why do we observe NOx going high if lime consumption is running to control it?
