The water utilization

water consumption and water balance were analyzed in detail for the jet bubbling reactor's(JBR)flue gas desulfurization(FGD)system in a thermal power plant.The water balance tests were conducted for the JBR's FGD system with and without gas-gas heater(GGH).The results show that water evaporation loss was the main reason for water consumption in the JBR's FGD system.In addition

water evaporation reduced greatly when the unit ran at low load

so the water balance was difficult to maintain under the low load conditions.The water balance situation will get worse for units without GGH.On this basis

this paper puts forward several optimization suggestions

such as increasing the circulating water usage and prolonging the washing interval time of the demister.
