摘要： A method for determining a sulfur trioxide content in a gas. A sample of the gas is taken, and a gas pressure of the sample is reduced. A wave number-resolved transmission measurement is carried out on the sample using a wave number-tunable monochrome light source, and a sulfur trioxide content is derived from the measurement. The measurement is carried out in the sulfur trioxide absorption band between 1360 and 1410 cm−1, in particular in a window around the sulfur trioxide absorption at 1365.49 cm−1. A method for operating a power plant, a measuring system for determining a sulfur trioxide content in a gas, and a power plant are adapted to determine a sulfur trioxide content in a gas.

摘要： In a method for exhaust gas aftertreatment, in which an exhaust gas to be aftertreated, which is produced during combustion of a fuel, is treated with a reducing agent. A constituent of the fuel is hereby also used as a constituent of the reducing agent, with the constituent of the fuel which is also used as a constituent of the reducing agent being hydrogen. The hydrogen is produced from water, and the reducing agent is a mixture of hydrogen and ammonia.
