The invention discloses a coke oven partial combustion chamber gas exchange and heating method. The method includes the steps that firstly, when an oven wall of an Nth coking chamber needs to be repaired, gas inflow of the Nth row, the (N+1)th row and the (N+2)th row of blast furnaces is shut off, and gas inflow of the (N-1)th row, the Nth row, the (N+1)th row and the (N+2)th row of coke ovens is started; secondly, the cover plate opening degree of air inlet doors of an Nth, an (N+1)th and an (N+2)th exchange opening and closing devices of a flue is increased, and the turning plate opening degree of an (N-1)th, the Nth, the (N+1)th, the (N+2)th and an (N+3)th exchange opening and closing devices of the flue is reduced; thirdly, after flame on the top of the furnaces is normal, a four-way small porous plate needing to be cooled and corresponding to a fire path is taken off and replaced with a blind plate, and the oven wall of the Nth coking chamber is repaired; fourthly, after the oven wall is repaired, the do
