In the operation of generators of this type an allowance of at least 1
gallon of clean generating water per pound of carbide should be made, and
the generator should be cleaned after slaking of every full charge. Where
lump carbide is used the lumps may become embedded in the residuum, if
the latter is allowed to accumulate at the bottom of the generating
chamber, causing overheating from slow and restricted generation, and
rendering the mass more liable to form a hard deposit and bring severe
stresses upon the walls of the generator by slow expansion.
26. GENERATING CHAMBERS.--(_a_) Must each be connected with the
gasholder in such a manner that they will, at all times, give open
connexion either to the gasholder or to the blow-off pipe into the outer
air.
(_b_) Must be so arranged as to guard against appreciable escape of
gas to the room at any time during the introduction of the charges.
(_c_) Must be so designed that the residuum will not clog or affect
the operation of the machine and can conveniently be handled and removed.
(_d_) Must be so arranged that during the process of cleaning and
recharging the back-flow of gas from the gasholder or other generating
chambers will be automatically prevented.
