Description: |
| Abstract:
I have provided my boiler with means for preventing priming, by which I mean the carrying of water out with the steam by reason of the rapid circulation of the water through the tubes, which in some cases is so violent as to cause to a serious extent the evil just mentioned. For this purpose I place in the steam-drum a submerged perforated or grid-like plate 13, situated below the normal water-line, preferably only a few inches below- the same. This plate may extend entirely across the steam-drum, or it may be placed only in that part of the drum which is opposite the ends of the tubes in which the most violent ebullition occurs. Even when the water is oily, which generally causes the most violent ebullition, the presence of the perforated baffle-plate is sufficient to check the foaming, and it renders it harmless.
Claim:
A steam-boiler having a steam and water, drum, water-tubes entering the same, and a perforated baffle-plate in said drum, submerged somewhat below the normal waterline and situated above the tubes. |
