    摘要: A method for treating odorous gases of a chemical pulp mill, according to which method odorous gases are combusted in a separate combustion device and flue gas generated therein is scrubbed. The scrubbed flue gas is led into a recovery boiler. The flue gas is scrubbed in a series of scrubbers wherein scrubbing solution discharged from one scrubber may be fed to a preceding scrubber.

    摘要: The invention relates to a method and an arrangement for the removal of concentrated odorous gases of a pulp mill. According to the method, the concentrated odorous gases containing sulphur compounds are collected from the odorous gases of the sulphite pulp mill and combusted with under air to oxidize the sulphur compounds, so that at least an essential part of the sulphur compounds is oxidized into elemental sulphur. The elemental sulphur is recovered in a liquid or solid form. It can be returned to the process or used in other processes.

    摘要: A method and a system for feeding combustion air of a soda recovery boiler to a furnace. The air is fed to the boiler furnace as primary air jets and auxiliary airjets, which are substantially shorter than the primary air jets. At least one primary airjet is placed between two opposite auxiliary air jets.
