The first steam engine was invented and manufactured by French physicist Denis Papan in 1688, and it had a cylinder and a piston. Watt is the inventor of the improved steam engine.
Who invented the steam engine?
James watt james watt, a Scottish inventor, is often called the inventor of the steam engine and a key figure in the industrial revolution. In fact, Watt was not the first person to invent the steam engine. In the 1st century AD, Alexander Hiro designed a similar machine .. 1698, and Thomas Zavili obtained the patent right to pump water with a steam engine. 17 12, Thomas Coleman, an Englishman, obtained a slightly improved patent for a steam engine. Niukaomen steam engine is inefficient and can only be used for coal mine drainage. 1764, watt became interested in this kind of machine when he was repairing Niukaomen steam engine. Although Watt received only one year's mechanical manufacturing training, he has an extraordinary genius for invention. His improvement of Cogate machine was so important that people thought he invented the first practical steam engine. Watt's first major innovation was the addition of an independent condensation chamber, which was patented in 1769. He also isolated the steam cylinder from the outside world and invented the double-acting engine in 1782. Together with some minor innovations, these inventions have improved the efficiency of steam engines by at least four times. In fact, the improvement of efficiency means the difference between a flashy device and a machine with great industrial value. 178 1 year, Watt also invented a set of gears to convert the reciprocating motion of the steam engine into rotary motion. This set of gears has increased the use of steam engines. Watt also invented centrifugal governor (1788), manometer (1790), counter, indicator, throttle valve and many other instruments that can automatically adjust the running speed of steam engines. Watt himself doesn't have a good business mind. However, in 1775, he established the Watt-Burton Company in partnership with Marlowe Burton, a very capable businessman and engineer. The company produced a large number of steam engines, and both shareholders became rich. The importance of the steam engine cannot be overestimated. Of course, many other inventions appeared in the industrial revolution, such as mining, smelting and many industrial machinery. Several of these inventions, such as the pulley shuttle (john kay, 1733) and the Leni spinning machine (James Hargraves method, 1764), all appeared before Watt started. Most other inventions only represent minor changes, and none of them can play a decisive role in the industrial revolution alone. However, the steam engine is different. It plays a key role. Without it, the industrial revolution would be beyond recognition. Before it, although windmills and waterwheels had certain uses, the main power source was always the human body, which seriously limited industrial productivity. With the invention of the steam engine, this limitation was eliminated. Now there is huge energy available for production, and the output has also increased greatly. 1973 oil embargo makes us realize how seriously the lack of energy will hinder the development of industry. This experience will make us realize the significance of Watt's invention to the industrial revolution. Besides being the power of the factory, the steam engine has many other important uses. 1783, Marquis Juferroy Dabans successfully used a steam engine to drive a ship. Richard Trevisi restrained himself from building the first steam locomotive. However, these two models are not successful economically. However, in a few decades, ships and railways have completely changed land and water transportation. Historically, the industrial revolution appeared almost simultaneously with the American revolution and the French revolution. Although people did not seem to have a clear understanding of the industrial revolution at that time, today we can see that its role in human daily life is obviously much more important than those two great political revolutions. Therefore, james watt is one of the most influential figures in history.
Who invented the steam engine?
The first steam engine in the world was the spinning ball invented by the ancient Greek mathematician Herod of Alexandria in 1 century.
About 1679, the French physicist Dennis Papen made the working model of the first steam engine after observing the steam escaping from his pressure cooker. Around the same time, Samuel Moran also put forward the idea of steam engine.
17 12 years, Thomas Newcomen and 1769 years, James watt made early industrial steam engines, and they all made their own contributions to the development of steam engines. 1807, robert fulton was the first to successfully use a steam engine to drive a ship.
Watt is not the inventor of the steam engine. Before him, the steam engine, newcomen Steam Engine, appeared a long time ago, but it consumed a lot of coal and was inefficient. Watt improved the efficiency of the steam engine to more than three times that of the original newcomen machine, and finally invented the modern steam engine, which really popularized the steam engine.

Who invented the steam engine?
One summer morning in Watt, the sun was shining, and the thrush was singing a sweet song in the tree. On the campus of Glasgow University in England, there is a man walking. He walked slowly up and down on the green lawn. He sometimes looked at the vast sky, sometimes at the winding playground, and sometimes frowned ... Suddenly, a smile appeared on his face and his mood suddenly became clear. He came up with an effective solution to the steam engine. He ran happily, his feet flying fast. In an instant, he appeared on the operating platform that accompanied him for many years. He is Watt, the inventor of the steam engine. Someone once said, "Watt invented the steam engine because he has superhuman genius and wisdom." Actually, it is not. To illustrate this problem, let's talk about Watt's diligent study and study. Make up a story The Enlightenment of Water Vapor With the development of intellectual education, Watt became interested in some objective things, and he became curious and delved into them. This laid a good foundation for his later invention of the steam engine. In Watt's hometown of Greenock, every family makes a fire to boil water and cook. Who cares about such a common thing? Watt left his heart. Is there a Huai? He watched his grandmother cooking in the kitchen. There is a pot of boiling water on the stove. The boiling water is boiling. The lid of the pot smacked and kept jumping up. Watt observed it for a long time and felt very strange. He wanted to know what the reason was, so he asked his grandmother. What makes the lid jump? Grandma replied, "The water is boiling, that's all." . Watt asked discontentedly, "Why does the water jump when the lid is opened?" Is something pushing it? Maybe my grandmother was too busy to answer him correctly, so she said impatiently, "I don't know." What's the point of children asking these questions? "Watt didn't find the answer with grandma, but he was unfairly criticized. He was very uncomfortable, but he didn't lose heart. For several days, whenever cooking, he squatted by the fire and observed carefully. At first, the lid was very stable. After a while, the water will boil and make a loud noise. On the ground, the steam in the pot came out and pushed the lid to jump. The steam kept rising, and the lid kept beating, as if a magician was hiding inside, doing tricks. Watt almost cried out for joy. He opened the lid, closed it again and again, and verified it again and again. He also covered the cup and spoon that sprayed steam. Watt finally figured out that steam pushed the lid to jump, and the power of this steam was not small. Just as Watt was in high spirits and ecstatic, grandma spoke again: "You child, you don't know what's funny about the kettle, go away quickly!" "She said casually. His grandmother is too impatient and subjective, and if she neglects it casually, it will almost dampen Watt's self-esteem and enthusiasm for exploring scientific knowledge. Old man, you don't understand Watt's heart at all, do you? What a revelation water vapor is to Watt! Isn't the physical phenomenon that water vapor pushes the lid of the kettle to jump off the water bottle the source of Watt's understanding of inventing the steam engine? 1769, watt changed the steam engine into a single-acting engine with great power. Later, after many studies, the trial production of the new steam engine was completed in 1782. With the linkage device on the machine, the simple motion turned into rotary motion, and the perfect steam engine was successfully invented. Due to the invention of the steam engine and the developed coal and iron industry in Britain at that time, Britain became the first country in the world to use steam to drive iron "seagoing ships". /kloc-in the 0/9th century, the reform of maritime transportation began, and some countries entered the so-called "steamboat era". Since then, ships have been sailing on the boundless ocean. Subsequently, coal mines, factories and trains all used steam engines. Manual labor was liberated and the economy developed. This is the result of the invention of the steam engine. Of course, this is also the credit of Watt, the inventor of the steam engine. Therefore, Watt is famous all over the world. Watt's life is full of hardships and struggles. What a bumpy road he has traveled. He created blessings for mankind in hardships and hardships and opened up a new milestone for human progress. Watt attaches great importance to study and practice. Learning enriched his wisdom; Practice has achieved fruitful results.
Who invented the steam engine? When exactly?
The first steam engine in the world was an air balloon invented by Herod of Alexandria in the 1 th century, but it was just a toy. About 1679, the French physicist Dennis Papen made the working model of the first steam engine after observing the steam escaping from his pressure cooker. Around the same time, Samuel Moran also put forward the idea of steam engine. Thomas Seville in 1698, Thomas Newcomen in 17 12 and james watt in 1769 made early industrial steam engines, all of which made their own contributions to the development of steam engines.
Who invented the steam engine?
The steam engine is a reciprocating power machine, which converts the energy of steam into mechanical work. The appearance of the steam engine caused the industrial revolution in the18th century. Until the beginning of the 20th century, it was still the most important prime mover in the world, and then it gradually gave way to internal combustion engines and steam turbines. From the end of 16 to the end of 17, the British mining industry, especially coal mines, has developed to a considerable scale, and it is difficult to meet the requirements of pumping groundwater only by manpower and animal power, and there are abundant and cheap coal as fuel on site. The needs of reality have prompted many people in Britain, such as Papan, savery and newcomen, to devote themselves to the exploration and experiment of "lifting water by firepower". The world's first practical steam pump made in savery won the British patent named "Friends of Miners" on 1698. He first filled an egg-shaped container with steam, then closed the steam inlet valve and sprayed cold water outside the container to condense the steam in the container to form a vacuum. Open the water inlet valve, and the water at the bottom of the mine is sucked into the container through the water inlet pipe under the action of atmospheric pressure; Close the water inlet valve, reopen the steam inlet valve, and use steam pressure to press the water in the container out through the drain valve. When the water in the container is drained and filled with steam, close the steam inlet valve and drain valve, and spray water again to condense the steam. In this way, the two egg-shaped containers work alternately and can continuously drain water.
Who invented the steam engine? Who improved the steam engine?
Watt invented the steam engine. I don't remember who improved it.
