The invention relates to a method for controlling combustion air in a boiler plant, wherein combustion air is supplied into a boiler located in a boiler building. Combustion air is taken both from the inside and the outside of the building in a suitable ratio, wherein the air flow (q1) taken from outside is used to supply part of the combustion air required by the boiler. The ratio (q1/q2) is determined at least on the basis of the temperature of the outside air and the load of the boiler. The invention relates also to an apparatus for controlling combustion air in a boiler plant. The apparatus comprises a combustion air duct (C) for conveying combustion air into a boiler located in a boiler building. Combustion air duct (C) is provided with a mixing section (1) connected to both the inside of the building for supplying inside air into the boiler and the outside of the building for supplying outside air into the boiler. The mixing part (1) is further provided with control devices (2, 3) for mixing the air flow taken from the inside (q2) and the air flow taken from the outside (q1) to a total air flow (q1+2) entering the combustion air duct in a desired ratio. The apparatus comprises means for measuring the temperature (t mix) of the air flow (q1+2) which are connected to a comparator unit arranged to control the control devices (2, 3) of the mixing section (1) for adjusting the ratio of said flows (q2, q1).
