advantage of using hydrogen cooling yahoo answers
Relevance. Rating Newest Oldest. Best Answer: Hydrogen is used for two reasons: The gas which fills any generator is also present in the generator's airgap and there due to high turbulence, it develops a quantity of friction loss, the so called windage loss.he only other gas used for cooling generators is air (basic reasons should be clear) which of course is used wherever possible in preference to hydrogen. Since about 1990 great progress has been made in the use of air cooling and nowadays it can be used on generators up to about 400MVA unit size. Source(s): At the high flow rates used and turbulence involved, the heat transfer to the hydrogen is not a problem and its thermal conductivity is not an issue.

Source(s): The advantages of using hydrogen fuel cells are that they are an alternative fuel to fossil fuels, like coal, oil and gas. Also, burning or reacting hydrogen with oxygen runs … electric motors and it's only emission is water vapour.The disadvantages of using hydrogen fuel cells is that hydrogen does not occur naturally on Earth and thus is not an energy source. It takes a great deal of energy to extract Hydrogen from water.efore I list the advantages and disadvantages, it is important to note that Hydrogen is simply a medium with which to store energy, it is NOT an energy source, such as wood, … gasoline, or atomic energy. The same is not true for Hydrogen. Some of the advantages of Hydrogen: -It no longer requires us to be reliant on Gasoline as an energy source. -It burns MUCH cleaner than other fuels, since it's only by-product is water.-In Fuel Cell use, it requires no combustion, which means fewer moving parts that can break in the engine.efore I list the advantages and disadvantages, it is important to note that Hydrogen is simply a medium with which to store energy, it is NOT an energy source, such as wood, … gasoline, or atomic energy. From Wikipedia. Hydrogen fuel. In a flame of pure hydrogen gas, burning in air, the hydrogen (H 2) reacts with oxygen (O 2) to form water (H 2 O) and heat. It does not produce other chemical by-products, except for a small amount of nitrogen oxides.n a flame of pure hydrogen gas, burning in air, the hydrogen (H 2) reacts with oxygen (O 2) to form water (H 2 O) and heat.

An open recirculating cooling system uses the same water repeatedly to cool process equipment. Heat absorbed from the process must be dissipated to allow reuse of the water. Cooling towers, spray ponds, and evaporative condensers are used for this purpose.Open recirculating cooling systems save a tremendous amount of fresh water compared to the alternative method, once-through cooling.lkaline Treatment Programs. There are several advantages to operating a cooling system in an alkaline pH range of 8.0-9.2. First, the water is inherently less corrosive than at lower pH. Second, feed of sulfuric acid can be minimized or even eliminated, depending on the makeup water chemistry and desired cycles. Air cooled advantages-no need for radiator, coolant, water pump etc. Less weight. Disadvantages-noisy, difficult to control temperature properly.Water cooled advantages-quieter, accurate temperature control, warm water available for heater. Disadvantages-need for radiator, water pump, coolant, water jacket around cylinders, therefore more weight and potential for breakdowns.champer · 8 years ago.Thumbs up.ater cooled advantages-quieter, accurate temperature control, warm water available for heater.
