How did James Watt improved the steam engine?

In around 1764, Watt was given a model Newcomen engine to repair. He realised that it was hopelessly inefficient and began to work to improve the design. He designed a separate condensing chamber for the steam engine that prevented enormous losses of steam.

How was the steam engine improved?

In about 1712 another Englishman, Thomas Newcomen, developed a more efficient steam engine with a piston separating the condensing steam from the water. In 1765 James Watt greatly improved the Newcomen engine by adding a separate condenser to avoid heating and cooling the cylinder with each stroke.

Why was the Watt steam engine more efficient?

The first major innovation of Watt's was to include a separate condenser so that the steam didn't have to be cooled in the same cylinder that contained the piston. This meant the piston cylinder remained at a much more consistent temperature, greatly increasing the fuel efficiency of the engine.

In May 1765, after wrestling with the problem of improving it, he suddenly came upon a solution—the separate condenser, his first and greatest invention.

What was the steam engine before James Watt?

Before James Watt, the existing steam engine was the one built by Thomas Newcomen. It was a reciprocating (piston) “atmospheric” engine. What that means is that the piston was really pushed by atmospheric pressure. This is completely different from all the other steam engines that found practical use later. These other engines use the pressure of the hot steam to push the piston.

How did Watt make the engine more powerful?

Third, Watt took the bold step of using positive (higher than atmospheric) steam pressure on the top of the cylinder, to push the piston down, instead of having atmospheric pressure push the piston. This made the engine more powerful, since the pressure pushing the piston was higher than the atmospheric pressure. To do this, Watt had to seal the top of the cylinder, to contain the steam pressure (previously, it was open to the atmosphere). This steam on the upper cylinder would also be evacuated to the condenser after it pushed the piston. It soon became obvious that he could also increase the pressure on the bottom of the cylinder to the same pressure of the top. Thus, the steam at the bottom wasn’t just a “filler” that would create a vacuum, but it also pushed the piston. The engine was now a “double acting engine”, because steam would push the piston from both sides. The fact that steam was pushing the piston meant that the piston now need to drive a rod, instead of a chain, in order to work in both tension and compression.

What was the Watt engine? What was its innovation?

Watt's innovation was the separate condenser, boosting efficiency. What people forget is that the Watt engine was not really powered by steam. When we think of a steam engine, we think of a device that admits steam into a cylinder; the steam expanding as it pushes against the piston creating the work. Watt's engine was much like Newcomen in that the steam was admitted to the cylinder in order to displace air (it was very low pressure steam). This steam was then condensed, creating a vacuum in the cylinder. It was atmospheric pressure pushing against the piston that generated work.

What engine did the Newcomen use?

Both the Newcomen and Watt steam engjnes were atmospheric engines. They both used steam to fill the cylinder under the piston so that the pump shaft weight could pull the piston upwards.

Why did Newcomen and Watt use condensation?

Because they couldn’t push steam out, both Newcomen and Watt used condensation to drastically decrease the volume of the steam/water, and create vacuum. But Newcomen did this inside the cylinder, while Watt added an external condenser, that also created a vacuum (when steam met the cold water outside the cylinder), so even low pressure steam inside the cylinder would be ”pushed out” to this vacuum in the condenser.

How did the Newcomen engine work?

The way the Newcomen engine worked was to have a vertical cylinder with a piston, the piston being connected to a crank via a chain. On the other side of the crank, the chain connected to a water pump and counterweight. Because of the chain arrangement, power could only be transmitted via tension (pulling from one side or another), in one stroke, when the piston went down. The piston would then be raised, also by tension, when the counterweight on the other side went down.

Why did Watt add sleeves to the cylinder?

This kept the cylinder warmer, at a more constant temperature, so there would be less energy loss bringing the cylinder up to working temperature (even with an external condenser, the cylinder would still cool down because gasses always cool down when they contract).

What did James Watt do?

James Watt was born on January 30, 1736, and he always had an interest in creating and innovating new things. At the age of seventeen years old, Watt had decided what he wanted to do with his life. He wanted to become a mathematical instrument maker.1To make that happen, Watt needed to travel to Glasgow where he would fulfill his goal. Watt traveled to Glasgow, where he then worked at the University of Glasgow as a mathematical instrument maker. Later in life, in the year 1755, he traveled to London where he met his master to train him in mathematical practices, design, and building. It wasn’t until 1765 that he began one of his most successful accomplishments in his life: creating the most efficient steam engine anybody had ever seen.

How did Thomas Newcomen use steam engines?

At the time, steam engines were one of the most powerful pieces of machinery used in the mines. The steam engine was used to provide mechanical power by using steam created by the engine. Workers would fill up a boiler with water, and a fire would then heat the boiler making steam. The steam would be transferred from the boiler to the cylinder through a pipe causing a piston to move up and down creating energy. This energy was spread throughout the mining sites to power other equipment and mainly pump water. Watt had finished repairing the steam engine and decided to put it to the test. While testing his newly repaired steam engine, Watt realized that more than a quarter of the steam created by the engine was being released and wasted, causing it to be inefficient when used in the work field. Watt knew his desire to innovate would lead him to improve this steam engine.   Watt then spent the next year on the problem causing the loss of steam while using the engine. After that year’s long work, Watt realized that the problem of the steam engine was the loss of latent heat. Realizing this, Watt remembered the many different scientists he met, one being Joseph Black. Black was a British chemist and physicist who was the first to develop the concept of latent heat. Watt had first learned about this concept from Joseph Black himself while working at the University of Glasgow. It wasn’t until May of 1765 that Watt finally figured out a solution. Watt realized that he could utilize one of his great inventions known as a separate condenser.2The separate condenser was made by Watt in 1765, just in time to use on the steam engine he had been trying to improve. The separate condenser was essentially a condensation chamber where the steam was transferred to. With the condenser and the working cylinder being separate, the condensation occurred without a significant loss of heat from the cylinder, ultimately preventing the loss of large amounts of steam. Watt had figured out a solution, but there was still an issue on how Watt would apply the separate condenser to the steam engine. Once he had figured this out, another old friend he had met, John Roebuck, had pushed him to make a small test engine. With loans from Joseph Black, Watt made a test engine. Within a couple of months, Watt transferred what he had done to the small prototype engine to the real steam engine. Even though Watt had fixed the initial issue, he was nowhere near done. He continued to improve the design of the engine by adding rotary motion. In doing this, it would eventually broaden the uses of the steam engine. Watt wanted to continue improving his design but had multiple financial setbacks while trying to do so.3

His daughter was named Margaret and was born in 1767. She died when she was 29. The marriage lasted around nine years; in 1773, his wife passed away during the birth of his third child. The child was stillborn.

How old was James Watt when he started his instrument making business?

After his venture in London, James Watt returned to Glasgow to establish his own instrument-making business. At the time, James was only 18 years of age. During this same period his mother passed away, and his father’s health deteriorated.

What did James Watt do to build the Newcomen engine?

Fascinated by the Newcomen engine, Watt began building miniature models using tin steam cylinders and pistons attached to driving wheels by a system of gears. Over the winter of 1763–1764, John Anderson at Glasgow asked Watt to repair a model of a Newcomen engine. He was able to get it running, but perplexed by its waste of steam, Watt began studying the history of the steam engine and conducted experiments in the properties of steam.

Who invented the steam engine?

James Watt (January 30, 1736—August 25, 1819) was a Scottish inventor, mechanical engineer, and chemist whose steam engine patented in 1769 greatly increased the efficiency and range of use of the early atmospheric steam engine introduced by Thomas Newcomen in 1712. While Watt did not invent the steam engine, his improvements on Newcomen’s earlier ...

What was the purpose of the Newcomen engine?

In 1759, a student at the University of Glasgow showed Watt a model of a Newcomen steam engine and suggested it might be used—instead of horses—to propel carriages. Patented in 1703 by English inventor Thomas Newcomen, the engine worked by drawing steam into a cylinder, thereby creating a partial vacuum which allowed the increased atmospheric pressure to push a piston into the cylinder. During the 18th century, Newcomen engines were used throughout Britain and Europe, mostly to pump water out of mines.

Why was the Newcomen engine so inefficient?

While Newcomen engines offered improvements over earlier steam engines, they were inefficient in terms of quantity of coal burned to make steam vs. power produced by that steam. In the Newcomen engine, alternating jets of steam and cold water were injected into the same cylinder, meaning that with each up-and-down stroke of the piston, the cylinder’s walls were alternately heated, then cooled. Each time steam entered the cylinder, it continued to condense until the cylinder was cooled back down to its working temperature by the jet of cold water. As a result, part of the potential power from the steam’s heat was lost with each cycle of the piston.

What was Watt's breakthrough?

However, Watt’s future success was in no way assured nor would it come without hardship. By the time he came up with his breakthrough idea for the separate condenser in 1765, the expenses of his research had left him near poverty. After borrowing considerable sums from friends, he finally had to seek employment in order to provide for his family. During a span of about two years, he supported himself as a civil engineer, surveying and managing the building of several canals in Scotland and exploring coal fields in the neighborhood of Glasgow for the magistrates of the city, all while continuing to work on his invention. At one point, a despondent Watt wrote to his old friend and mentor Joseph Black, “Of all things in life, there is nothing more foolish than inventing, and probably the majority of inventors have been led to the same opinion by their own experiences.”

What did James Watt do in his teens?

The young Watt was an avid reader and found something to interest him in every book that came into his hands. By age 6, he was solving geometrical problems and using his mother's tea kettle to investigate steam. In his early teens, he began to exhibit his abilities, particularly in mathematics. In his spare time, he sketched with his pencil, carved, and worked at the tool bench with wood and metal. He made many ingenious mechanical works and models and enjoyed helping his father repair navigational instruments.

What is the name of the chamber that a steam engine uses to condense steam?

Developed in May 1765, Watt’s solution was to equip his engine with a separate chamber he called a “condenser” in which condensation of the steam occurs. Because the condensing chamber is separate from the working cylinder containing the piston, condensation takes place with very little loss of heat from the cylinder.
