ascension pipe मीनिंग इन हिंदी

It ran continuously along the row of benches within the retort house, and each ascension pipe from each retort descended into it.
Each retort ascension pipe dropped under the water level by at least a small amount, perhaps by an inch, but often considerably more in the earlier days of gas manufacture.
Within each retort-house, the retort benches would be lined up next to one another in a long row; each retort had a loading and unloading door; affixed to each door was an ascension pipe, to carry off the gas as it was evolved from the coal within.
However, after the early years of gas, research proved that a very deep, excessive seal on the hydraulic main threw a backpressure upon all the retorts as the coal within was gasifying, and this had deleterious consequences; carbon would likely deposit onto the insides of retorts and ascension pipes; and the bottom layer of tar with which the gas would have to travel through in a deeply sealed main robbed the gas of some of its illuminating value.
