The steam has a number of uses in a hospital including heating of the building, domestic hot water, humidificaction, sterilization and a number of other uses. It can also provide cooling with absrobption chillers. Several of the older college campuses have central steam plants and when a new building is built, it is usually connected to the steam system.

I think it used to burn coal in the boilers  but uses natural gas now. At one time, they were looking a burning trash to generate steam but that turned out to not be economically feasible.
