"explosion" type of situation that is created. Why is this? Does this have to do with the heat of fusion?
For example, plunging a large amount of ice into a boiler.

thermal shock.....sudden rise in pressure....not fusion

Hey that is one question that provokes a lot of thinking......
The explanation for the above phenomenon can be from different fronts. For example,
1. Coefficients of expansion.
Here the coefficients of expansion due to heat of the two bodies in contact may be different. This results in the hot body to contract when it comes into contact with a cold body and the cold body to expand when it comes into contact with the hot body. Say in your example when the boiler contracts and the ice expands it results in increase in pressure and thus might explode.
2. Chemical Composition:
This is called temperature detonation. For example in a particular type of Nitro Glycerine bomb, the detonation is done by introducing a fuse of higher temperature than that of the cool explosive.
3. Vaporisation;
When the cold medium comes into contact with the hot one, it vaporises thus increasing the pressure. This might also lead to an explosion.

Any "explosion" would be from the production of steam and the shattering effect of heat stress. Ice does not give off heat when melting, it absorbs heat (thus keeping an ice box from heating up.) It has nothing to do with the heat of fusion as the direction is wrong.

It is the immediate transfer of so much energy that causes what appears to be an explosion. Energy is created in the melting of ice and conversely in the area of the water that is being immediately cooled.

That is dangerous, coz it causes change within the current pressure - the sudden paradox of 2 ends of differential pressure causes the middle process system to collapse... the idea is that u disturb the vapor pressure suddenly, which causes the media to collapse under reigning pressure...

It has to do with differential expansion. The area being heated or cooled will expand or contract so quickly that it will shatter.
