h v invented a certainnew and use- Imp-royement in Smoke-Consuming De- .vices, whereof the; following is a specifica- 131011, reference being had to the. accompanynfildrawings v a v 4 I0, y invention relates-to boilers and coinmeans whereby thesteam generated thereingis superheated in a retort adjacent to the boiler furnace, and injected below ,the coal fire in the furnace, with the air supplied to the latter, and directed in a above said; fire, whereby the smoke arising from said fire is forcibly mixed and consumed with the injectedfluid.

scribed is embodied in an internally fired boiler, and includes an annular retort in 'terp osedbetween the boiler furnace and the boiler tubes, out of contact with the fuel,

' and so arranged that the steam traversing a passageway in the walls of said retort is superheated by the gases of combustion in contact with said walls and being directed by said retort to the boiler tubes.-
