Description: |
| Abstract:
It will be understood by those skilled in the art that the boiler above described affords many economical advantages. The combustion-chamber is large, and the gases will combine with a minimum quantity of air and will undergo perfect combustion before they begin to be cooled by striking the tubes. The best possible conditions of heating are thus afforded. Again, the hot gases tend to remain at the top of the bank of tubes, while the gases that are spent and are cooling descend to the mouth of the flue. A low stack temperature and a very high initial temperature of the gases thus result.
Claim:
A boiler having an upwardly-extending bank of tubes, a smoke-flue extending from the lower portion of the bank, a fire-chamber at the side of the boiler-setting having an annular extension around the bank of tubes into and around which the gases enter laterally from the fire-chamber, said annular extension being of greater cross-sectional area than the tube-surrounding space above, said extension entering the tube-chamber at a place exterior to the bank of tubes and at a level above the base thereof. |
