This is advisable to makeallowance for expansion when there is a fire on only one side of thewall. The sections in Figure A apply to the side walls at the rear of thebridge wall. For the furnace section in front of the bridge wall, weadvise that the walls be battered from the grate level to the closing-inline near the middle of the boiler shell.
