Are water-coal slurry boilers less efficient compared to pulverized coal boilers? respective efficiency ranges.
Think about it: to evaporate the water from all that fuel in water-coal slurry, additional heat must be consumed::$
Why are coal-water slurry boilers still in use given their low efficiency? By how much is their efficiency low?
Because it becomes a fluid, transportation and storage are easier. Coal powder poses an explosion risk, and certain areas require explosion-proof design; these issues do not exist with water-coal slurry. Efficiency isn’t taken into account; however, the moisture content of water-coal slurry is usually around 30%.
