US20090077969A1 - Heat Transfer Methods for Ocean Thermal

A means is provided to produce fresh water from seawater on both the boiler side and the condenser side of an OTEC power plant. Part of the warm ocean surface water is evaporated, and its vapor transfers heat to the working-fluid boiler as the vapor condenses. The condensation of the vapor provides fresh water. On the condenser side, the condensation of the working-fluid …

Jan 07, 2022 · Boiler types. The watertube boiler is employed for high-pressure, high-temperature, high-capacity steam applications, e.g. providing steam for main propulsion turbines or cargo pump turbines. Firetube boilers are used for auxiliary purposes to provide smaller quantities of low-pressure steam on diesel engine powered ships.

Fresh water Generator Working Principle ? Types, Uses

Jan 27, 2022 · This steam evaporator aboard HMS Belfast distilled up to six tons of fresh water per hour for the boiler and for drinking. An evaporator, distiller or distilling apparatus is a piece of ship's equipment used to produce fresh drinking water from sea water by distillation. As fresh water is bulky, may spoil in storage, and is an essential supply for any long voyage, the ability to …

History of the Steam Engine - Steamboat

Steam generators, also known as boilers, are hungry creatures and all the more so in the early years of the 1800's. Once brought to life they consume tons of fuel and thousands of gallons of fresh water every hour. Each stroke of the steam engine discharged water and heat from the boiler into the atmosphere.

Steam generator (boiler) - WikiMili, The Best Wikipedia Reader

Jul 28, 2021 · A monotube boiler, a type of steam generator (early 1900s White Motor Company). A steam generator is a form of low water-content boiler, similar to a flash steam boiler. The usual construction is as a spiral coil of water-tube, arranged as a single, or monotube, coil.Circulation is once-through and pumped under pressure, as a forced-circulation boiler. [1]

Steam Chapter 1 Flashcards - Quizlet

The _____ located near the boiler separates air and water in the condensate return, expelling the air pumping the water back into the boiler Vacuum pump All boilers are now rated on a proportion of 100 for steam and 165 for water, with steam at 2 pounds pressure or water at the boiler

The New SS France - CGT French Line - 1912 | GG Archives

The consumption of fresh water must reach nearly 800 tons. The power thus obtained is 45,000 horsepower, and the production of steam per hour of 270,000 kilos. To avoid the need to carry more than a thousand tons of fresh water for the supply of boilers, the ship is equipped with evaporator boilers in which the seawater is distilled.

The sea plant—A source of power, water and food without

Limitless quantities of fresh water can be produced at a cost of less than five cents per thousand gallons. The warm water leaving the boilers of the power plant is deaerated, then boiled under vacuum conditions to produce steam. The heat to evaporate steam comes from the water and lowers its temperature a few degrees.

Oscillating Paddle Engines - Shipping Wonders of the World

As much as one-quarter of the total water fed to the boiler would be removed in this way. The condensers of the early engines consisted merely of a jet of sea water in a tank into which the exhaust steam was allowed to escape. The steam was condensed by the water jet and the condensate (condensed steam and sea water) was pumped back to the boiler.

Water Supply System | Saving Earth | Encyclopedia Britannica

When preheated salt water enters a low-pressure chamber, some of it rapidly boils, or flashes, into water vapour. The vapour is condensed into fresh water on heat-exchange tubes that run through each stage. These tubes carry incoming seawater, thereby reducing the heat required from the boiler. Fresh water collects in trays under the tubes.

Hot Water Pressure Increase in Hot Water Tanks or Boilers

Water is at its highest density at 3.98 °C = 1000 kg/m 3 or 1 g/cm 3. The correct SI unit of density of water is ρ = 1000 kg/m 3. [also FYI, 1 m 3 = 1,000,000 cm 3]; Specific weight of water = 62.4 lb/ft 3 (IU) or 9.81 kN/m 3; Specific weight of seawater = 64 lb/ft 3 (IU) or 10.1 kN/m 3 - must be all that extra salt making it more dense, so we float better in seawater than in fresh water, right?

May 11, 1999 · Cold saltwater circulated through the condenser to convert the warm steam to fresh water, which was then pumped into fresh water feed tanks for use by the boilers to make steam that goes back to the engines. Cutting off steam: To perform maintenance on the engine, all steam is cut off. To cool the engine at an even rate to prevent warping, the
