Abstract: A process for burning solids on a sliding fire grate system where each of the combustion control criteria are measured and controlled individually for each grate plate comprising the grate system.

Abstract: A method and apparatus for introducing a liquid or gaseous treatment medium into a flue gas stream wherein a total adjustment value for controlling the amount of active substance in the treatment medium is generated by an actual value measurement of a flue gas component and a comparison with a set value, and the treatment medium is injected through a plurality of nozzles into the flue gas stream flowing through a flow chamber. The flow chamber is divided into a three-dimensional matrix of partial flow chambers, each of which comprises a nozzle and measuring devices for detecting the temperature and flow speed of the flue gas stream in the partial flow chambers. The active substance is injected with a constant volume flow of treatment medium in an amount determined by calculation of an individual adjustment value of active substance for each nozzle. The total of the individual partial adjustment values does not exceed the total adjustment value of the active substance.

Abstract: In a process that is used to regulate the quantity of a processing medium at is used to reduce the nitrogen monoxide content in the exhaust gases generated by combustion processes, in which the quantity that is used is regulated as a function of the nitrogen monoxide content, a processing medium blow-by nominal value (8) that is changed as a function of the nitrogen monoxide content value (3) measured in the exhaust gas (2) is used in addition to a pre-set nitrogen monoxide nominal value (7) .

Abstract: In order to recover or dispose of ammonia or ammonia compounds from mixtures of dust that occur during combustion processes, during subsequent gas cooling, or during subsequent gas scrubbing, the dust that is created is mixed in batches with water in a closed system at a temperature that is lower or equal to the temperature at which the dust leaves the combustion, cooling or scrubbing process, and the resulting vapors are drawn off in a vacuum.
