Description

Technical Field

[0001] The utility model relates to a water-coal slurry furnace which is advantageous for ash conveying. Background Art

[0002] In the original production, a slag remover was used at the bottom of the wind chamber. After the coal ash cooled, the chain plate was used to remove the coal ash and put it into a cart.
