Yes, but how much UV depends on what's burnin / how hot its burning. Otherwise they mostly put out IR.

We use UV/IR combo Flame detectors at work for this purpose.

IIR, hydrogen flames can emit enough of their energy in the UV for that to be a serious issue - both direct human exposure, and degradation of exposed surfaces and equipment.
