Advanced and clean gasification of solid wastes by downstream hot flue gas cleaning with high temperature filters and catalytic beds
- Univ. Complutense of Madrid (Spain)
Thermochemical gasification of solid wastes has two main advantages over their incineration: a lesser flow rate of exit /stack gas is produced, smaller gas cleaning devices are thus required, and no formation of dioxins/furans, because of the reducing gas atmosphere. Nevertheless, at least two other problems remain to be solved: the destruction or elimination of the halogenated tars produced, and the removal of the heavy metals from the flue gas. Two small pilot plants are being used at University of Madrid to study and solve these problems. They are based on a bubbling fluidized bed gasifier and on a riser type gasifier. They have a continuous feeding of waste (1-4 kg/h) and downstream vessels for high temperature gas cleaning with filters and catalysts. 2 refs., 2 figs.
