The tops of the chambers are usually stayed by stronggirders resting upon the tube plates and chamber back plates. In plates. The end plates of the boiler in the steam space and belowthe combustion chambers are stayed by longitudinal stays passingthrough the whole length of the boiler and secured by double nutsat each end. The tube plates are strengthened by stay tubes screwedinto them. Where natural or chimney draught is used the tubes are generallymade 3 or 3i in. outside diameter and are rarely more than 7 , but where forced draught is employed they are usuallymade 2 J in. diameter and 8 to 8| ft. long. A clear space of ij the tubes is almost always arranged for, irrespective of sizeof tubes. Stay tubes are screwed at both ends, the threads of the two endsbeing continuous so that they can be screwed into both tube plates;.
