The Story of Watt Inventing the Steam Engine (150 words)

Watt (1736- 18 19) was born in England and was the inventor of the first steam engine in the world. As a child, Watt was sickly and timid. He often likes to play alone, but he likes to use his head.

One day, he saw the boiling water in the kettle suddenly lift the lid and make a "poop-poop" sound. He asked his grandmother curiously, "Why does the lid jump?" Grandma told him that this is the power of steam in the pot. Small watt thought, the power of steam is really great, if only it could be used! This incident inspired him to invent the steam engine.

Watt came from a poor family and went out with his father to learn crafts after graduating from high school. /kloc-when he was 0/9 years old, he went out alone as an apprentice and worked in a cold workshop for ten hours every day. The harsh environment honed his will and made him learn many skills of repairing experimental instruments.

At the age of 20, Watt got help from his friends and entered the university laboratory to be a repairman of teaching tools and instruments. He learned a lot of new knowledge there. On one occasion, he was responsible for repairing the model of the steam engine, thinking while repairing it; I should build a better steam engine than it. Watt successfully trial-produced the first steam engine in 1782.

Extended data

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. Therefore, Watt is a reformer of steam engine.

/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.

The experiment of using steam engine as propulsion power on ships began in 1776. After continuous improvement, Fulton, USA made the first practical open-wheel propulsion steam engine ship "clermont". Since then, steam engines have been used as propulsion power on ships for more than one hundred years.
