Thermal treatment of sewage sludge pyrolysis and gasification

Abstract

The treatment of sewage sludge and, at the same time, a great demand for energy for heating and electricity production is a problem of modern society. The technology of modern times makes it possible to satisfy two needs at the same time. The first problem is the treatment of sewage sludge, sewage sludge disposal and environmental pollution. Another problem is the necessity to replace fossil fuels with alternative fuels in power plants and heating plants. Sewage sludge can be disposed of in several ways. The most effective treatment is thermal. The thermal treatment neutralizes harmful substances from the sludge and at the same time produces heat. The burning of sludge can be made in the rotary kilns, reactors for the pyrolysis and gasification.
