Significance: It blew the horn of the industrial revolution and brought mankind into age of steam.

1679, Dennis papen made the working model of the first steam engine.

1765, British instrument repairman james watt invented the steam engine with condenser and cylinder wall separated. Watt's creative work made the steam engine develop rapidly. He turned the machine that can only carry water into a widely used steam engine, which doubled the thermal efficiency and greatly reduced the coal consumption.

/kloc-Since the late 8th century, steam engines have been widely used not only in mining, but also in smelting, textile, machinery manufacturing and other industries. It has increased the textile output in Britain by five times (from 1766 to 1789) in more than 20 years, provided a large number of consumer goods for the market, accelerated the accumulation of funds and put forward urgent requirements for the transportation industry.

Historical function

The steam engine promoted the development of the whole industrial revolution. Traditional horsepower or water power cannot provide the power needed for industrial revolution, and the development of steam engine energy has brought more effective and powerful power to the world. Although the ancients began to explore this aspect in the 2nd century BC, it was not until Watt's steam engine was put on the market that the commercial value of the steam engine was really opened.

The appearance of steam engine promoted the development of metallurgy, coal mine and textile industry. The appearance of steam engine and the mechanization of textile industry increased the iron consumption of industry. Because Britain is rich in iron ore and coal mines, the increase in demand has stimulated the improvement of iron smelting technology and coal mining industry and accelerated the pace of industrialization. 1804 steam engine train and 1807 steam engine boat greatly improved the transportation conditions and assisted the development of the industrial revolution. ?
