In the prior art, during the operation of the first vacuum unit a and the second vacuum unit B of the waste incineration power plant, the vacuum pumps in the single unit are used and prepared. When the first vacuum pump a1.1 in the first vacuum unit a fails, the first backup pump a1.2 can be put into operation, which ensures that the first vacuum unit a does not stop. However, if the first backup pump a1.2 fails at the same time, the first vacuum unit a can only be stopped because no pump is available. Likewise, the second vacuum assembly B also suffers from the same problems.
