Abstract: The invention is, on the one hand, a method for drying products, especially corn or articles, in the course of which the products to be dried are traversed by a drying gas, the moisture content of the drying gas is diminished by contacting it with a desiccant liquid, and the desiccant liquid is at least partly regenerated after the contact. According to the invention, the drying gas stream flows through at least two layers of products to be dried successively, and before or after flowing through each layer of products it is brought into contact with the desiccant liquid.

Abstract: Flue gases from a glass-melting furnace, after passing through an elevated recuperator, descend through a vertical cooling column into a horizontal convective boiler before being exhausted into a smokestack. Entering water, circulating essentially in counterflow to the flue gases, is preheated in an exit compartment of the boiler and passes via a flow regulator into the main boiler chamber and thence into a bank of vertical pipes on the periphery of the column. On rising through these pipes, the water is partly converted to steam which is superheated in an entrance compartment of the boiler before being fed to a load, the remaining water being returned to the boiler chamber.

Abstract: The invention is used in the field of pressure-intensifying stations of natural gas and oil pipelines.The essential character of the process according to the invention is that steam is produced in boilers heated with the outgoing flue gas of the gas turbines driving the compressors (pumps), the steam is conducted into steam turbine for driving further compressor(s), pump(s).Main feature of the equipment according to the invention is that the ratio of the simultaneously operating gas turbines and steam turbines may vary from the equivalent to tripple value, the ratio is suitably double, and the stand-by machine unit is driven always by gas turbine, separate flue gas boiler is connected to each of the gas turbines, while the boilers are equipped with supplementary and/or substituting automatic heater.Advantages of the invention include the following:reduces the self-consumption by about 1/3rd,improves safety of the pressure-intensification,realizable in existing pressure-intensifying stations.

Abstract: A method of and apparatus for drying products with a gas stream passing the product to extract moisture therefrom and a contacting device producing at least one desiccant liquid layer in the vicinity of the product to be dried, which liquid layer removes moisture from the gas. The gas stream is bubbled through a substantially horizontal liquid layer or can pass between liquid film conducting elements. The desiccant liquid is continuously regenerated. By means of several partial gas streams and a contacting device having more separated liquid film modules, a counter-current type of drying is possible. The product to be dried can be heated to a predetermined temperature by the desiccant liquid through the drying gas stream.

Abstract: The invention relates to a system for the periodical steam cooling of the inner spaces of internal combustion engines, aiming partly to reduce the contaminations in the exhaust gas and partly to increase the ratio of the heat to be converted into mechanical work.

Abstract: Reasons of ecology, health and prevention of corrosion require firing methods and furnaces with which the contents of soot and uncombustible gases such as carbon monoxide, hydrogen, hydrocarbons as well as nitrogen oxides and sulfur trioxides do not excess certain levels. This is obtained by a firing method in which a fuel is decomposed with deficient amounts of primary combustion air to combustible gases. Such gases are combusted by the admixture of secondary and tertiary combustion air amounts whereby a flame is obtained which is extended in space and time and, thus, the temperature of which does not rise above moderate values such as 1400.degree. C. Prior to being exhausted, the combustion gases are thoroughly mixed so as to obtain perfect combustion of possibly subsisting combustible substances. Exhausting takes place with heat withdrawal so that cool and pure combustion gases enter the ambiency.

Abstract: A heat exchanger in a close cycle gas turbine power plant has, on its heat abduction side, a system of cooling units connected to it by means of which the efficiency of the plant is considerably increased. Such units consist of evaporators and vapor turbines with condensers and air coolers, the vapor turbines being driven by vapors generated in the evaporators. The latter, in turn, are heated by the heat abduction side of the heat exchanger in the main cycle. The exhaust vapors are precipitated in condensers and cooled down by air coolers and recoolers and partly circulated back to the heat abduction side of the heat exchanger in the main cycle.
