Claim 18

Apparatus as described in claim 15 including a deflection plate means mounted in said chamber and positioned along and normal to the axis of said second outlet means.

Claim 19

Apparatus as described in claim 9 wherein said first inlet means has a different cross sectional area than said first outlet means.

Claim 22

A method as described in claim 18 wherein said low pressure slurry is a mixture of coal and water.

Claim 23

A method as described in claim 18 additionally comprising: (a) forming a sump for the storage of slurry; (b) removing slurry from said sump for injection into said vortex; (c) conveying said removed low pressure fluid to said sump for storage.

Claim 24
