摘要： The invention relates to a method for energy recovery after combustion of solid combustible material, for example solid waste material. In the method, the cooling of flue gas, which flue gas is obtained by combustion of solid combustible material, is carried out in two steps, wherein in a first step the flue gas is cooled to a temperature of 620 to 680 °C via radiant heat transfer and in a second step the flue gas is further cooled by convection heat transfer with water to a temperature of at most 250°C, through which convection heat transfer a heating of water to saturated steam and subsequently to superheated steam is also carried out, which superheated steam is used as such for energy-demanding processes and/or is used for converting the superheated steam into electricity.
The invention also relates to a device for energy recovery after combustion of solid combustible material.-

摘要： The invention relates to a method for obtaining an acidic liquid from flue gas originating from the combustion of chlorine-comprising material, in which at least the following steps are applied:
the removal of solid particles from the flue gas via a two-field electrofilter;
absorbing hydrochloric acid from the flue gas in at least one absorption column with packing material whereby a solution is obtained; and
adsorbing pollutants in the solution on one or more activated carbon filters, whereby an acidic liquid is obtained, wherein the solution has a concentration of HCl of at least 3 wt%.
The invention also relates to a device for purifying flue gas, and also relates to purified flue gas per se.-

摘要： The invention relates to a method for cleaning flue gas originating from the combustion of chlorine-comprising material, in which at least the following cleaning steps are applied to the flue gas:
- cooling and absorbing pollutants in a quench;
- absorbing pollutants in one or more packed columns;
- adsorbing pollutants on one or more activated carbon filters;
- absorbing pollutants in one or more absorption columns; and
- expelling cleaned flue gas thus obtained,
characterized in, that an absorbent flows through the packed columns in the opposite direction of flow to the flue gas and consists of at least 90 wt% water upon entering one or more absorption columns.
The invention also relates to a device for cleaning flue gas, and also relates to cleaned flue gas per se.-

摘要： The present invention relates to a method for processing various liquid chlorine-comprising waste streams, the method comprising the following steps: mixing the different waste streams into a mixture; burning the mixture at 1100-1400°C where combustion gases are released; cooling the combustion gases via a steam boiler to 250-300°C; removing particles from the combustion gases in a two-field electrofilter; cooling the combustion gases in an economizer to 180-220°C; bringing the flue gases in contact with an absorbent in at least two packed absorption columns; obtaining a hydrochloric acid solution; wherein the absorbent has a pH
