Only if you qualify it to add "Anthracite coal stoker designed to burn pea coal".
There are many good Anthracite hand fired and stoker boilers on the market. The strong points of each vary. How important each is depends on your particular needs. The Antratube and Coalgun designs are the highest operating efficiency stoker boilers with documented tests to back up the claim. Even though the test was done 50+ years ago!
