Question

Who improved the steam engine produced by newcomers?

Answer 1

Thomas Newcaomen invented the atmospheric engine in 1712, and it is commonly referred to as a Newcomen engine. The engine worked by condensing steam drawn into the cylinder, producing a partial vacuum that allowed the piston to be pushed into the cylinder by atmospheric pressure. It was the first practical system to use steam to perform mechanical tasks.

Complete answer:
Newcomen engines were widely used in Britain and Europe, mostly to extract water from mines. Hundreds were built over the course of the 18th century. Later engine designs by James Watt were an improved version of the Newcomen engine that nearly doubled fuel efficiency.The "atmospheric" design was used in the first steam engines, which were introduced by Thomas Newcomen in 1712. When steam was added, the weight of the object being pushed by the engine forced the piston to the top of the cylinder at the end of the power stroke.

The cylinder was then cooled with a water mist, causing the steam to condense and create a partial vacuum in the cylinder. The top of the piston was pulled down by atmospheric pressure, which lifted the work object. Watt found that it took a lot of heat to warm the cylinder back up to the point that steam could reach the cylinder without condensing right away. When the cylinder was sufficiently wet, it was filled with steam the next power stroke could commence.

Watt realised that by adding a separate condensing cylinder, he could save the heat required to warm the cylinder. After the power cylinder was filled with steam, a valve on the secondary cylinder was opened, allowing the steam to flow through it and condense, triggering the power stroke. To keep the steam condensing, the condensing cylinder was water cooled.

As the piston rose to the top of the power stroke, the valve was closed to allow steam to fill the power cylinder. The end result was the same cycle as Newcomen's, but without any cooling of the power cylinder, which was ready for another stroke almost immediately.Watt worked on the design for many years, adding the condenser and making changes to almost every aspect of the design.

Watt, for example, conducted a long series of tests on how to seal the piston in the cylinder, which significantly decreased leakage during the power stroke and prevented power loss. All of these improvements resulted in a more dependable design that used half the amount of coal to generate the same amount of electricity.

Hence, James Watt improved the steam engine produced by newcomers.

Note: The majority of steam engines are large and powerful. As a result, moving them from one location to another is difficult. In comparison to other heat engines, steam engines have a lower performance.
