This is weird. I'm adding a partical generator to my 3d engine. It uses alpha blended pictures, but when the z-buffer is enabled some of the particals are transparent and some of them arn't. Smoke trail without zbuffer:

That is as it should be.

When you are rendering your particles you need to disable z-buffer writes. Note you should not disable z-buffer reads as you would then be able to see particles through solid objects, like walls and stuff.
