| 1. A method for injection of a solution of a compound into a gas at elevated temperature, evaporating the solution and decomposing
the compound in the gas at the elevated temperature, which method comprises
injecting the solution into an injection channel being a corrugated cylindrical, helically grooved or an at least partly tapered
injection channel being provided into at least a portion of an outer channel and being surrounded by and spaced apart from
the outer channel;
passing the gas along space between inner wall of the outer channel and outer wall of the injection channel and along inner
space of the injection channel;
evaporating the solution in and on inner wall of the injection channel; and
decomposing the compound in and on the inner wall of the injection channel and in the gas.
