\begin{abstract}
Based on the principle of active anti-wear method, seven metal anti-wear
devices of types A through G were designed and numerically evaluated by
comparing the erosion distribution of the local water wall surface in
this work. The result shows: an approximate vertical triangle structure
with an inclined upper surface and a vertical lower surface, is the most
ideal structure for reducing the erosion rate. The type G and ash
deposition can be combined into this ideal structure. The simulation
results based on the type G show that the erosion rate increases
correspondingly with the increasing inlet velocity and particle size and
is somewhat mitigated by the addition of cohesive particles. The height
of the ash deposition zone decreases with decreasing particle diameter
and proportion of cohesive particles. The type G is preferred to be
tested on the CFB boiler for half a year, and achieved a good anti-wear
effect.%
