fluidised bed combustion (CFBC) have been studied along with their relative merits and demerits. One of CFBC's key advantages is its ability to use a wider range of fuels, including pet coke. Another advantage of CFBC is that it does not slag as the combustion temperature in CFBC boilers is low (8000C to 9000C) and reduces the NOX emissions.
CFB Boiler. The fuel-handling system receives petroleum coke, coal, and limestone and conveys it to stock-out and storage areas.
Pet coke has become a competitive fuel, which has made it very popular in CFBC Boilers. CFBC technology is able to take advantage of this fuel as the main fuel in a remarkable way. Petroleum coke basically comes in two types named the fluid coke and delayed coke.
