The increase of temperature communicated to steam by superheating it.
The attempt to dry the steam by superheating it in the nest of tubes forming the steam space was found to be impracticable.
These figures represent the added fuel necessary for superheating a definite weight of steam to the number of degrees as given.
By superheating the steam the water that exists in the low pressure stages of the turbine may be reduced to an amount that will not cause trouble.
If the boiler has superheating surface, the temperature of the steam should be determined by the use of a thermometer inserted in a thermometer well.
A superheater, properly placed within the boiler setting in such way that products of combustion for generating saturated steam are utilized as well for superheating that steam, will not in any way alter furnace conditions.
The submerged surfaces in boilers at the mean water level should be considered as water-heating surfaces, and other surfaces which are exposed to the gases as superheating surfaces.
Loss due to the superheating of the moisture in the air supplied from the atmospheric temperature to the temperature of the flue gases.
These engines have now been removed to a vessel nearly double the tonnage of the Valetta, and the latter fitted with engines by Mr. Penn on the superheating principle.
The trial trip of the Valetta on Thursday was most satisfactory, not only as regards the engines, but still more so as to the application for the superheating process.
By the superheating process the steam is raised in passing along the pipes in the smoke-box (where the heat is about 650 deg.
The superheating apparatus evidently effected a most important saving in fuel, but until an average of many days' working can be obtained, it would be difficult to estimate the exact amount economized.
It is this loss of power and waste of heat which the superheatingprocess is intended to prevent, and which will, of course, allow a reduction of from twenty-eight to thirty per cent.
Defn: The increase of temperature communicated to steam by superheating it.
These are also made by combining two or more boilers and using them as a feed water heater or a superheater, for facilitating the production of steam, or to be used for superheating steam.
Another refinement, and one which goes to the very essence of a heat motor, is the method of superheating the steam.
In practical operation there are two (or more) of the steam superheating chambers 3, working alternately, and one of them is being heated up while the other is superheating the steam.
Further, superheating increases the volume of a given weight of steam, thereby reducing the consumption of steam required to develop a certain power and consequently increases the capacity.
What is the advantage of superheating or increasing the temperature of the steam?
The two great objects in this 1832 patent weresuperheating steam in tubular boilers, and propelling ships by forcing a stream of water from the stern at a speed of at least double that of the vessel.
Those latter patents also embrace the principle ofsuperheating steam, practically shown many years before,[217] and still used by marine engineers of modern times.
One object of the Binner Downs experiment was to further curtail this loss of power by increasing the heat of the steam while in operation in the cylinder, since called superheating steam.
The presence of the solid phase will prevent the supercooling of the liquid; and the presence of the vapour phase will prevent the superheating of the liquid.
The same reluctance to form a new phase is observed also in the phenomena of superheating of liquids, and in the "hanging" of mercury in barometers, in which case the vapour phase is not formed.
Should the range fire be maintained through the day or night the supply of hot water will be excessive and superheating is the result.
In the use of furnace heaters, superheating is likely to occur during cold weather when a hot fire must be used over a long period of time.
Mr. Stott points out that superheating could reduce this by 6 per cent.
The steam is carried in a pipe down through the middle of the central flue, so that superheating is secured, which it is claimed makes a saving of over 8 per cent in fuel and water.
A large size steam pipe passes from dome in rear through boiler to engine in front, superheating steam and avoiding condensation from exposure.
The chief advantage of this apparatus is that the enormous superheating space enables a lower temperature to be used for the "fixing.
In this apparatus the superheater is directly above the generator; and there is only one superheating chamber instead of two.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "superheating" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: cooking; insolation; warming
