Thomas Savery was the first person to build a steam engine. Thomas was an English military engineer. The purpose he built it was to pump water out of coal mines. The design he made had no moving parts, it only had a boiler which was a steam chamber with its valves located on the surface. It had a pipe leading to the water in the mines. Water is heated in the boiler chamber until its steam fills the chamber forcing out any remaining water or air. The valves are then closed and the chamber would be sprayed on the top with cold water, forming it into a vacuum. When the valves reopened, the vacuum would suck up all the water in the mine.But this …show more content…
He was also Thomas Savery’s partner. Newcomen’s steam engine design increased the efficiency by setting a moving piston inside a cylinder. This technique is still used in many steam engines today. In his engine, he replaced the large open boiler chamber with a cylinder. A piston is fitted inside the cylinder, which was used to create motion instead of a vacuum. When steam filled the cylinder from an opening valve, it is sprayed with water causing it the steam inside to condense into water and create a partial vacuum. The piston is forced down by the pressure of the air outside, producing a power stroke. The piston was connected to a beam, which was connected to a water pump at the bottom of the mine by a pump rod. The movement of the piston causes the water pump to suck up the water, this happen through the connection of the piston, beam, water pump. Although Newcomen’s designs too had many faults, some of them include wasted heat and fuel. Figure 2 shows Thomas Newcomen’s steam
