A New Steam Generator

we learn from the Philadelphia Gazette that
recently invented steam-generating apparatus
has been pat in operation in that city, which
promises to avoid the chief difficulties and dan
gers OF the boiler and to obtain power at
greatly reduced cost. The apparatus consists
of double coil of pipe into which water and
air are forced in dense spray and around
which the IRE rises vertically The proportions
OF air and water forced in by the pump ara

being worked by the exhaust steam. The ex-
periments show saving in fuel over the old
method that is scarcely credible but its pro-
prietors claim for its constan. performance
saving OF only fifty per cent; also that it can
not explode, since the coils which are OF lap
welded boiler iron, will bear two thousand
pounds to the inch Of pressure, and the safety
valve is as large as the diameter of the coils. -
There Is also no body Of water in the generator
to be intensely heated under the pressure, as in
tue boiler, which body OF water, will instantly
take on the form OF steam if the boiler be broken
