How Parsons marine steam turbines powered ships

In the second part of this series, the author talked about the story of the first little toy turbine. This article focuses on marine steam turbines and their applications. Parsons main thrust for the steam turbine was for generating electrical power, but he also had his eyes on applying the steam turbine to drive ships of all kinds. He hit the jackpot here. There is quite a story to be told

Velox Boiler: Principle, Construction & Working -

Velox boiler is a water tube forced circulation boiler. It has a gas turbine driven air compressor, which compresses the air. This compressed air enters into the vertical combustion chamber, as result, high rate of heat release from the fuel, which increases the flue gases velocity up to the sound velocity.

Marine Turbine Engines - How Does a Steam Turbine

2020-12-23 · Marine turbine engines have mostly been replaced by large two stroke diesel engines as a means of ships propulsion. This was mainly because of the great difference in fuel consumption, even modern oil-fired steam boilers consumption was up to 30% more than that of today's big diesels. The superheated steam enters the high pressure (HP) stage (the astern turbine is on the same shaft) and

Boiler - WikiMili, The Best Wikipedia Reader

2020-7-28 · A fuel-heated boiler must provide air to oxidize its fuel.Early boilers provided this stream of air, or draught, through the natural action of convection in a chimney connected to the exhaust of the combustion chamber. Since the heated flue gas is less dense than the ambient air surrounding the boiler, the flue gas rises in the chimney, pulling denser, fresh air into the combustion chamber.

Gas Turbines - an overview | ScienceDirect Topics

The gas turbine cycle is referred to as the Joule or Brayton cycle, and this was discussed briefly in Section 3.2.5: the basic cycle is shown in Fig. 17.2 (which is exactly the same as Fig 3.17).The closed cycle gas turbine consists of a compressor, turbine, heater and cooler. Hence energy is added to the working fluid in the heater (analogous to the boiler of a steam turbine).
