James Watt, a Scottish innovator, significantly advanced the steam engine during the height of the Industrial Revolution. In 1764, he enhanced Thomas Newcomen’s original model by incorporating a separate condensing chamber. This addition vastly improved the engine’s efficacy. Watt’s version required a mere quarter of the coal that Newcomen’s did, which not only made it more efficient but also remarkably affordable for industrial use.

By 1775, Watt had teamed up with entrepreneur Matthew Boulton, forming the renowned partnership, Boulton & Watt. This collaboration quickly became one of the era’s leading ventures. Their partnership witnessed the development of 496 engines by 1800, boasting a total combined power output of around 11,200 horsepower. The triumph of Watt’s erudite design catalyzed a surge in coal mining and the extensive deployment of steam engines throughout Europe. This included significant uptake in nations such as Belgium, France, Germany, and the Netherlands.

This fusion of steam engines with electrical generators stands as a monumental achievement in power generation. Its impact reverberated through society, catapulting widespread electrification and fueling industrial growth during the Industrial Revolution and the subsequent periods.

Charles Parsons and the Invention of the Modern Steam Turbine

Sir Charles Algernon Parsons, born in 1854, is acclaimed as the father of the modern steam turbine. His invention transformed power generation and influenced several sectors, including marine transport and naval warfare. Parsons laid the groundwork for the creation of high-powered, efficient steam turbines widely used in the 20th century.

Parsons’ Reaction Turbine Design

In 1884, Parsons introduced a steam turbine that operates using a reaction principle. Unlike its predecessors, this design employed steam expansion in stages, optimizing the extraction of thermal energy. Breaking down the steam expansion into stages allowed Parsons to effectively control the high-speed, high-energy steam, which could surpass 1,700 miles per hour. This approach is key to contemporary turbine efficiency.

Scaling up Parsons’ Turbine for Power Generation

Parsons’ turbine was easily scalable, marking a significant advantage. Initially producing 7.5 kilowatts, its capacity escalated to 50,000 kilowatts during his era. The unique design of his turbine permitted the construction of larger units than reciprocating engines. In 1912, a turbo-generator with 25,000 kilowatts was the world’s largest and most efficient. By 1923, a single unit from Parsons’ company achieved 200,000 kilowatts, surpassing reciprocating steam engines.

“The steam turbine can be constructed for much larger outputs than any reciprocating engine.” – Sir Charles Parsons

Parsons’ Impact on Marine Transport and Naval Warfare

The adoption of Parsons’ steam turbines significantly improved marine transport and naval warfare. The “Turbinia” in 1897, powered by his technology, achieved 34 knots in a race, faster than Royal Navy destroyers relying on older engines. Utilizing steam turbines in ships enhanced their speed and efficiency, transforming the shipping industry and naval engagements.

Gustaf de Laval’s Impulse Turbine

A Swedish engineer, Gustaf de Laval, developed an impulse turbine that differed greatly from Parsons’ model. De Laval’s design was simpler, cheaper, and didn’t require a pressure-tight environment. However, it was less effective. This turbine featured a single rotor with curved blades. Steam would expand and gain speed through a nozzle before striking the blades. It was especially effective for smaller, quick applications.

Auguste Rateau’s Pressure Compounded Impulse Turbine

Auguste Rateau from France took the impulse turbine further by adding pressure compounding. In 1903, he patented a design with several stages, each having nozzles and a rotor. This allowed the steam to expand in phases, greatly improving energy extraction. His creation was commonly used in powering ships and generating electricity.

Charles Curtis’ Velocity-Compounded Impulse Stage

American inventor Charles Curtis introduced the velocity-compounded impulse stage in 1896, known as the Curtis wheel. This design combined both stationary and moving parts to draw out energy from the steam in phases. It offered superior efficiency and more power than the simple impulse turbines. In 1903, the first 5-MW steam turbine, using Curtis’ innovation, was delivered by General Electric to Chicago’s Commonwealth Edison Co., marking a milestone in steam turbine technology.
