One is a new sort of steam pump, essentially two devices like de Caus', but attached to a single boiler. A key invention is the addition of cooling around the containers to force the steam to condense. This produces a partial vacuum inside the chambers, which is used to draw a volume of water into the containers through a pipe, thus forming a pump.
The energy consumed in manufacturing ductile iron pipe was 19.55 MJ per kg and volume of emissions released during manufacture was 1.430 kg CO 2 per kg, compared to 68.30 MJ per kg of energy and 4.860 kg CO 2 per kg emissions for PVC pipes, and 1.24 MJ per kg and 0.148 kg CO 2 per kg for concrete pipes of the same diameter.
In the steam-iron process the iron oxidizes and has to be replaced with fresh metal, in the Lane hydrogen producer the iron is reduced with water gas back to its metallic condition, after which the process restarts. The chemical reactions are [3] 3Fe+ 4H 2 O → Fe 3 O 4 + 4H 2 Fe 3 O 4 + 4CO → 3Fe + 4CO 2. The net chemical reaction is: CO ...
In the mid-1750s, the steam engine was applied to the water power-constrained iron, copper and lead industries for powering blast bellows. These industries were located near the mines, some of which were using steam engines for mine pumping. Steam engines were too powerful for leather bellows, so cast iron blowing cylinders were developed in 1768.
A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages. [ 1 ] [ 2 ] A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure (HP) cylinder , then having given up heat and losing pressure, it exhausts directly into one or more larger-volume low-pressure (LP ...
A steam pipe explosion in New York City's Flatiron District on Thursday morning sent steam spewing high above buildings and created a crater-like hole on 5th Avenue. The explosion, which occurred ...
A steam pipe explosion sparked road closures and evacuations in Manhattan’s Flatiron district on the morning of July 19, police confirmed.The New York Police Department said the closures were ...
Steel pipe (or black iron pipe) was once the most popular choice for supply of water and flammable gases. Steel pipe is still used in many homes and businesses to convey natural gas or propane fuel, and is a popular choice in fire sprinkler systems due to its high heat resistance.
