First the easy part. Generally, you probably already know it is a Phalaenopsis (moth orchid). If it wasn't tagged with a variety name, you will never know which specific moth orchid variety you have. Too many white Phalaenopsis that nobody kept the breeding records on. Just enjoy it for what it is.
Leaf damage. I the damage is not growing larger, it is probably heat or sun damage. If the damage is getting larger, it is probably bacterial damage; cut the leaf off an inch into healthy green leaf tissue. I recommend a very sharp blade. Preferably sterilizing the blade before and after cutting (boiling water, folloed by cooling, works well).
