High-pressure steam engine
A high-pressure steam engine is a machine that converts the energy of steam grown under intense pressure into mechanical work. Water is heated in a boiler until it becomes steam at high pressure, which then expands rapidly to move pistons or turbines. This movement drives machinery or generates electricity. Used mainly in the 19th and early 20th centuries, these engines were powerful and efficient for their time, especially in ships and industrial settings. They differ from low-pressure engines by operating at higher steam pressures, which allows for more compact and potent design but requires careful handling due to safety concerns.
