Hospital waste-incineration plant with natural gas auxilliary combustion system

A hospital waste-disposal facility in the form of a `thermal waste-treatment plant' incorporating recovery of the heat yielded from the hospital waste requiring disposal and its feeding into the city's transmitted-heat system, and also complete with the appurtenant subsidiary systems for flue-gas and waste-water clean-up has been constructed for the Allgemeines Oeffentliches Krankehaus (Public General Hospital) of the spa city of Baden by Vienna. Natural gas is used as the auxiliary fuel for heating-up and temperature maintenance. This article describes, in particular, the structure of the flue-gas cleaning facility which, for environmental safety reasons, has an extremely complex four-stage layout, and the design of the extensive waste-water treatment plant.
