Beschreibung
Zusammenfassung:	The present invention combines sewage by-products such as sludge cake, with a composition which includes iron-containing waste materials to form a heat-producing composition. First, waste materials from the conversion of iron ore to pig iron or steel combine with a reducing metal, such as aluminum or magnesium, and a small portion of a mineral acid to form a reaction mixture which gives a heat output superior to many conventional fuels. Then, this composition is admixed with sludge cake from a city sewage plant to produce a fuel which not only utilizes city sewage to some advantage but also gives a good heat output. The materials are processed in several steps to produce either a shaped or loose composition, a portion of which is then heated to a reaction temperature.
