WEBINAR

Water conservation in coal-fired power plants

About this webinar

The vulnerability of the power generation industry to constraints in water availability is widespread and growing, and this is increasing the pressure on power plant operators to conserve water. This webinar will discuss where water can be conserved or recovered within pulverised coal-fired power plants. It will include ways of saving water in bottom ash handling, pollution control (flue gas desulphurisation), and cooling systems. Cooling typically accounts for the largest usage of water (where water is the coolant), and wet flue gas desulphurisation is the second largest use at wet-cooled plants. Techniques for recovering water from the pulveriser and pre-dryer exhausts, and from the flue gas are also discussed. There is an opportunity for power plants to become a supplier of both electricity and water, if sufficient water can be economically recovered from the flue gas. This could be a way forward for some coal fired power plants in the future, as well as helping to solve local fresh water shortages.
