Author: Daniel G. Teleoaca – Maritime Chief Engineer Steam turbines have been a cornerstone in power generation for over a century, particularly in marine applications where they provide propulsion and electrical power. This article delves into the intricacies of a vessel steam turbine generator system, exploring its components, operational principles, maintenance requirements, common issues, and…
Steam has been a cornerstone of maritime propulsion and industrial processes for centuries. It is used in various applications onboard vessels, such as propulsion, power generation, heating, cooling, sterilization, and desalination. Steam can be classified into two main types: saturated and superheated. Onboard vessels, understanding the differences between saturated and superheated steam is crucial for…
Boilers are essential components of numerous industries, including marine operations, where they play a crucial role in generating steam for propulsion, power generation, and other onboard processes. Safety valves are critical elements of boiler systems, designed to protect against potentially hazardous conditions by relieving excess pressure. However, for safety valves to effectively perform their function,…
The steam condenser is a critical component on board vessels that plays a crucial role in the efficiency and operation of boiler and steam-powered systems. It enables the conversion of exhaust steam from the consumers or main propulsion or power generation systems back into water, allowing for reuse and maximizing energy efficiency. In this comprehensive…
The evaporation of water into a gas results in the production of steam and in order for the process of vaporization to take place, the water molecules need to be provided with an adequate amount of energy so that the bonds that hold them together (hydrogen bonds, etc.) may be severed. The term “latent heat”…
Onboard vessel, in general, saturated steam is produced into the oil-fired boiler or the exhaust gas boiler. There are special type of systems, where steam is used for propulsion or electrical generation into the steam turbines. On these cases steam need to be superheated and at high pressure and steam generating systems are more complex…
