  The black string solution is a model of black holes in (3+1) dimensions that
can be related to the BTZ (2+1) dimensions black hole solution. This object can
be seen as a cylindrical black hole. In this work it is considered the black
string Hawking temperature obtained by the Hamilton-Jacobi method and a
description of a system composed by a black string and a thermal reservoir,
considering the thermal equilibrium state.
