An Experimental Study on Petroleum Coke in a Bubbling Fluidized Bed Combustion Chamber

V. Chokkalingam, Dr. K. Murugu Mohan Kumar

Abstract


Fluidized bed combustor is a modern technology to burn solid fuels including the bio-fuels, coal, petroleum coke etc. In FBC air is forced through a bed of inert material and fuel at a velocity that causes the bed to become fluidized .Combustion of petcoke (100%),it is mixed with limestone for suitable molar ratio of Ca/S(calcium/sulphur)ratio. In this experimental study of petcoke firing, the convection contributes 70% to 80%and the radiation contributes 5%to 20% of the outside heat transfer co-efficient (ho). Petcoke is co-fired with coal (singaronei coal) and limestone, higher boiler capacity, improved efficiency, less smoke and less ash handling. In 100% petcoke firing sox emission is1181.5ppm and Nox rate is 101ppm and the combustion efficiency is 45.72% whereas the petcoke and coal firing the sox rate is 946.5ppm and Nox rate is 89.5ppm and the combustion efficiency is 61.95% so the petcoke mixed with coal combustion is higher efficiency and environmental friendly.
