Two gentlemen in France have patented an apparatus that promises to be of much use in economizing the fuel for high pressure engines. The plan consists in conducting the steam, after its action on the piston, into a close vessel, which likewise holds the cold water intended for the boiler : this latter rapidly acquires, by the condensation, a temperature of 98 or 100a centigrade. The water is then conducted into another vessel, in which it deposits the earthy particles and other extraneous substances, that it may contain before entering the boiler. This arrangement presents the advantage of forming much less calcareous deposit, and of not obliging the boilers to be so often cleaned
It’s Time to Stand Up for Science
If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.
I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.
If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.
In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.
There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.
