The Value Proposition for Large scale CFB Coal Technology for Indian Sub-continent

The webinar will focus on the technical, economic and environmental benefits of CFB boilers that may be customized for the Indian power market.

CFB technology also offers several additional commercial advantages. Its inherent low emissions design avoids the cost of installing and operating expensive DeNOx and DeSOx flue gas cleaning equipment. Supercritical and ultra-supercritical CFB technology further increase conversion efficiency thus lowering both CO2 emisions and the overall cost of electricity production. Long-term operating data clearly demonstrates that CFB clean coal technology has a lower forced and planned outage rate and thus higher reliability than conventional coal and biomass combustion technologies. All these features should be very attractive.

Below are some of the questions discussed during the webinar:

  • How is NOx removed in the CFB process, as it is claimed that SCR is not needed?

  • Any operating experience with firing rice husk and straw, wheat husk and straw, juliflora, etc.?

  • Any operating experience with typical Indian coal with around 45% ash, 0.3% sulfur, 0% moisture, and HHV of around 2800 kcal/kg?

  • Is any special external protection required for furnace pressure parts because of circulating bed material erosion in CFB boilers?

  • How do you protect against high-temperature corrosion induced by high chlorine in fuel and high Na and K in fuel ash? Do you use any metal spray over the superheater and reheater?

  • Now that the coal market is declining and biomass, being carbon-neutral, is gaining popularity, will you be offering biomass to the Indian market? If yes, will it be with USC cycles?

  • Do you provide any refractory on the superheaters and reheaters? If yes, what is the thickness?

  • What kind of bed material leakage arrest measures have been taken for the furnace and cyclone?

  • What is the impact of firing plastics and other items in CFB on flue gas norms?

  • How do you handle fuel with >35% surface moisture in the SHI FW fuel feeding system? What special care should be taken?

  • Is there a commercial value of ash coming from CFB boilers? Can it be used in the cement industry?

  • What USC steaming parameters would be selected for a 350 MW USC CFB cycle firing biomass in India?

  • How do you feed coal with 45% moisture? Is any special care required?
