Fluidised Bed combustion systems to control pollution

Fluidised Bed combustion systems to control pollution

ABSTRACT:

With the escalating prices if oil and gas during the last decade the world power industry shattered and there is a move to shift the power industry from oil to coal as coal is abundant in comparison to oil. Coal plays a major role in the Indian economy. It accounts for 36% of annual energy produced. Though it is cheap & plentiful, the environmental and health impact of coal use is becoming more and more severe due to its deteriorating quality. The economy is expected to grow at a rapid pace and it is quite likely that India may also have to use inferior quality fuels which may be available at lower cost for economic generation of power. In light of such a scenario there is an increasing need to find ways of limiting pollution of air through the use of cleaner technologies and more efficient processes. Steam turbines can run on a variety of fuels but coal continues to remain a popular choice. However, the traditional coal-fired plants suffer from two major drawback: overall efficiency levels are low and pollution levels are high.Growing environmental concerns and the need to improve conversion efficiency levels have led to the development of clean coal technologies. The most popular of the new clean coal technologies are Fluidised Bed Combustion (FBC) The Fluidised bed combustion chamber plays a vital role in reducing the sulphur dioxide and nitrous oxide pollutants.
This paper describes CFBC technology development, process description, technical and environmental performance .
