WE know the surface orbital velocity of a black hole is "C"
The quantum effect produces faster and slower photons.
The majority of photons are trapped in orbit. the faster ones spiral outward.
The slower photons could neither spiral outward or maintain orbit.
What the heck happens to them? Can we save the black hple?

It is not orbital velocity.
It is the escape velocity. In order for a black hole to exist the diameter of the mass should be less than the diameter at which the escape velocity is C.
Now rewrite your question.

Hi. Photons equate to energy. Some energy obviously escapes which is why we see the bright area in the accretion disk. Once a photon is 'absorbed' by the black hole it just adds it's energy. The black hole does not need saving!
