Internal Recirculation - Circulating Fluidised Bed Combustion (IR - CFBC) The boiler with its simplified, cost-effective and efficient design provides improved performance. Benefits include high combustion efficiency, high reliability and availability, low maintenance cost, reduced erosion, enormous fuel flexibility and low emission.
Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels.. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials (sand, limestone etc.) through which jets of air are blown to provide the oxygen required for combustion or gasification.
In addition, BHEL has earlier executed the 4×125 MW Surat Lignite Power project at Nani Naroli in district Surat, Gujarat, also involving CFBC technology. CFBC boilers are highly fuel flexible and can burn a wide variety of fuels, including Lignite, efficiently. CFBC boilers are also highly environment friendly with very low pollutant emissions.
