Introduction Lowrank coal (LRC) is a widely used energy source for power plants, contributing about 45% of the total global coal reserves [1]. However, the most apparent difference between the LRC and bituminous coal or anthracite coal is its high moisture content, which causes many problems in the utilization processes [2].

Wet cooling towers (WCT) are widely used to reject the unutilized heat in coal thermal power plants (TPPs). But this comes at the cost of excessive water consumption. Adoption of aircooled condensers (ACC), also known as dry cooling systems, in all proposed Indian TPPs would reduce their water consumption by 26% in 2030. However, power producers are reluctant to install ACC due to technical ...
