The Rise of the Steam Engine - National Coal Mining Museum
2022年3月17日 The pressure was limited by the quality of the boiler which in early days was made of copper and then later riveted iron plates. These could fail at anything more than a very low pressure, resulting in a catastrophic explosion. Instead the engine made use of atmospheric pressure hence its original name. Its structure was like a seesaw.

The Blast Furnace: 800 Years of Technology Improvement
2023年2月23日 Coke-fired blast furnaces were not any cheaper to operate than charcoal-fired ones, and the use of coke resulted in sulfur impurities in the iron, which, while not a problem for castings, made the iron unsuitable for conversion to wrought iron. As of 1750 only 10% of the pig iron produced in Britain was from coke-fired furnaces.

Coking coal of the United States—Modern and historical coking
Coking coal, or metallurgical coal, has been produced in the United States for nearly 200 years. Coking coal is primarily used in the production of coke for use in the steel industry, and for other uses (for example, foundries, blacksmithing, heating buildings, and brewing). Currently, U.S. coking coal is produced in Alabama, Arkansas, Pennsylvania, Virginia , and West Virginia.

How does coke and coal play into steel making?
2016年6月22日 In either coke or non-coked coal, the quality of the coal affects the quality of the steel. Metallurgical coke is made from bituminous coals by a distillation process. Ash deposited by the coal must be kept to a minimum, preferably below 10% of the original mass. The ash can lower furnace temperatures and leave non-combustible materials.

Iron Making Boundless World History - Lumen Learning
Abraham Darby made great strides using coke to fuel his blast furnaces at Coalbrookdale in 1709. However, the coke pig iron he made was used mostly for the production of cast iron goods, such as pots and kettles. He had the advantage over his rivals in that his pots, cast by his patented process, were thinner and cheaper than theirs.
