In the case of mono sewage sludge incineration, a solution may be created that enables sewage sludge ash, which may still have a low proportion of unburned carbon, to be discharged from a mono sewage sludge incineration plant. This is achieved by a method for the post-combustion of sewage sludge ash obtained in a mono sewage sludge incineration in a rotary kiln by means of a hot and a low oxygen content, such as an oxygen content of 5-10 vol. % oxygen. The gas stream from the rotary kiln may escape the sewage sludge ash and is fed to the gas flow. This sufficiently hot gas flow may cause oxidation or afterburning of unburned carbon contained in the sewage sludge ash.

Process and device for improving of synthesis and/or flue gas velocity field solves technical problem of local increase of velocity and resulting non-homogeneous flue gas field resulting in uneven temperature and concentration distribution within flue gas field by providing for homogenization of flue gas field using strategically placed obstacles in the flow field such as flaps or similar devices.

A membrane method processing system and process for a high-concentration salt-containing organic waste liquid incineration exhaust gas is described. The system consists essentially of a waste liquid incinerator (I), a gas-solid separator (II), a heat exchanger (III), an air blower (IV), an anti-caking agent storage tank (V), a membrane method dust cleaner (VI), an induced draft fan (VII), a check valve (VIII), and a desulfurization tower (IX). The present invention introduces the dust collecting membrane into the tail gas treatment system and utilizes the small pore size and high porosity of the dust collecting membrane to prevent inorganic salt particles from entering the internal of the filter material and agglomerating there. When the humidity of the gas entering the dust collector increases during the dust removing process, the anti-caking agent is also introduced into the tail gas treatment system to change the surface structure of the inorganic salt crystal to prevent the crystal from agglomeration.
