@ECHO OFF

set array[1]=22750289 512
set array[2]=22750289 5600
set array[3]=22750289 5612

for %%N in (1,1,3) do (
    echo %array[%%i]%
    echo %array[1]%

For this you need to enable delayed variable expansion using setlocal:

@echo off

setlocal EnableDelayedExpansion

set array[1]=22750289 512
set array[2]=22750289 5600
set array[3]=22750289 5612

for /L %%N in (1,1,3) do (
echo !array[%%N]!)

endlocal

Notice that the variables are no longer available after endlocal.

For more information about delayed variable expansion reference this thread.

Also worth nothing that you're going to want to use a for /L loop instead of the regular for loop you've got there.
