Looks like a Dendrobium to me.
Looks somewhat like my Den Polar Fire in shape and pattening, not sure on colour as it's difficult to tell in the pic.
Here is a link to a pic of Den Polar Fire.
Successful market launch: Dendrobium Polar Fire
although even if it looks similar it might not be. There are a lot of Dendrobium hybrids which are not registered, so you could have one that just looks like something else. I don't even think Polar Fire is a registered hybrid, just a trade name for something.
What I think is more certain is that it is a Dendrobium Hybrid which probably has a high influence from Dendrobium phalaenopsis (don't confuse this with a Phalaenopsis orchid which is something different).
