Each boiler has two dampers, which are hung and can be workedindependently of each other. When the fires are at rest during themeal hours or at night, these dampers are always shut as close aspossible consistent with not sending the smoke out at the furnacedoors. When the furnaces are in full operation these dampers arealways full open; if less draught is required, it is not to be got byclosing these dampers, but by closing the damper in the main flue asshown further on. There are two main flues—one goes direct to thechimney, the other is the economiser flue through which the smokepasses to the chimney if the economiser is in operation, which italways is, unless on very rare occasions and for special purposes.
