Book excerpt: Excerpt from The Theory of Drying and Its Application to the New Humidity-Regulated and Recirculating Dry Kilns The qualification in regard to air is necessary, for the sake of exactness, for the following reason: In any given space the total actual pressure is made up of the combined pressures of all the gases present. If the total pressure ("vacuum") is 2 inches, and there is no air present, it is all produced by the water vapor (which saturates the space at 101 F.); but if some air is present and the total pressure is still maintained at 2 inches, then there must be less vapor present, since the air is producing part of the pressure and the space is no longer saturated at the given temperature. Consequently further evaporation may occur, with a corresponding lowering of the temperature of the water, until a balance is again reached. Without further explanation it is easy to see that but little water can be evaporated by a vacuum alone without addition of heat and that the prevalent idea that a vacuum can of itself produce evaporation is a fallacy. If heat be supplied to the water, however, either by conduction or radiation, evaporation will take place in direct proportion to the amount of heat supplied, so long as the pressure is kept down by the pump. At 30 inches of mercury pressure (one atmosphere) the space becomes saturated with vapor and equilibrium is established at 212 F.If heat be now supplied to the water, however, evaporation will take place in proportion to the amount of heat supplied, so long as the pressure remains that of one atmosphere, just as in the case of the vacuum. Evaporation in this condition, where the vapor pressure at the temperature of the water is equal to the gas pressure on the water, is what is commonly called "boiling," and the saturated vapor entirely displaces the air under continuous operation. Whenever the space is not saturated with vapor, whether air is present or not, evaporation will take place, by boiling if no air be present or by diffusion under the presence of air, until an equlibrium between temperature and vapor pressure is resumed. Relative humidity is simply the ratio of the actual vapor pressure present in a given space to the vapor pressure when the space is saturated with vapor at the given temperature. It matters not whether air be present or not. One hundred percent humidity means that the space contains all the vapor which it can hold at the given temperature - it is saturated. Thus at 100 per cent humidity and 212 F. the space is saturated, and since the pressure of saturated vapor at this temperature is one atmosphere, no air can be present under these conditions. If, however, the total pressure at this temperature were 20 pounds (5 pounds gauge), then it would mean that there was 5 pounds air pressure present in addition to the vapor, yet the space would still be saturated at the given temperature.

This book was released on 2017-10-13 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Manual of Design and Installation of Forest Service Water Spray Dry Kiln The 'best thing that can be said. Of any dry kiln is that when it is run by a properly informed operator the temperature, humidity, and circulation are constant and uniform. In an endeavor to pro duce a kiln in which each Of these could be regulated independently Of the others, the Forest Products Laboratory designed and devel oped the Forest Service Humidity Regulated Water Spray Kiln, 1 described in this bulletin. The principle Of forced circulation and humidity control by means Of sprays Of water was the basis Of the first patent taken out in 1912 and is the main feature Of the present kiln. This dry kiln is well adapted to commercial use in the kiln drying Of refractory hardwoods Of large dimensions and Of green lumber Of all kinds, and has attracted attention wherever commercial practice has been forced to realize that drying equipment incapable Of close operation will not dry green lumber economically. Experience has Shown that the details Of good design and work manship are Often disregarded, with the result that the kiln fails to function as intended. By adhering to the principles herein set forth any competent engineer should be able to design or construct an installation Of the Size suited to the peculiar needs of a given plant.

Book excerpt: Drying Principles and Practice presents the fundamental principles that underlie drying arts as a basis for explaining the behavior of a drying plant. This book begins with an introductory chapter, followed by an account of the phenomena that causes the influence of moisture on its host material and manner in which moisture may be expelled by heat into the humid surroundings. The quantitative description of the way a moist material dries and how it dries under commercial conditions are also provided. The remainder of this text is devoted to surveying less-common methods of drying, moisture-measurement techniques, dryer-control systems, and aspects of the choice and design of industrial dryers. This publication is valuable to engineers, but is also a good source for senior undergraduate and postgraduate students engaged in studies of heat with mass transfer.
