Experimental study on zero liquid discharge (ZLD) of FGD ...

Dec 01 2018 · FGD wastewater was sprayed into the flue duct in a coal-fired power plant and the wastewater contacted with the high temperature (120150) flue gas. When the FGD wastewater was evaporated the residual solid and salt in the wastewater would be captured by the downstream dedusting system (ESP Electrical Static Precipitator).

Design and application of a novel coal-fired drum boiler ...

Sep 30 2020 · In this paper the design and operation of a novel coal-fired circulating fluidized bed (CFB) drum boiler that can generate superheated steam using saline water were introduced. The natural circulation water dynamics with a drum was adopted instead of the traditional once-through steam generator (OTSG) design so that superheated steam can be generated for the better performance of

Design and application of a novel coal-fired drum boiler ...

Pollutant control technologies were adopted to reduce pollutant emissions. Based on the field test the recommended water standard for the coal-fired CFB drum boilers was determined. With the present technology the treated recovery wastewater can be reused in steam-injection boilers to generate superheated steam.
