Abstract

The air-steam engine is an analogue of the internal combustion engine or the gas turbine engine. When air is compressed by a piston or a compressor in the air-steam engine, the temperature of the air is substantially increased. The injection of water instead of a liquid fuel at the end of a compression stroke brings about the evaporation of the water and an increase in the pressure of a working liquid, which pressure causes a piston stroke in the opposite direction or causes turbine blades to rotate so that motion is transmitted to the other mechanical parts. The engine makes it possible to save resources by using the heat of ambient air for the operation thereof.

Description

Steam Engine Description

The field of technology. Industrial engineering.

The level of technology. An air-steam engine (VPD) is the same device as an internal combustion engine (ICE) or a gas turbine engine (GTE) and it belongs to the same level of technology as engine building. Its difference lies in the fact that the internal combustion engine or gas turbine engine works with the help of combustible fuel, and the HPA works with the heat of compressed air and the properties of water to be converted into steam. (I.V. Voznitsky. Marine internal combustion engines. St. Petersburg, Morkniga, 2008, Chapter 1. Introduction to ICE course, 1.3. ICE duty cycles, p. 12).

Disclosure of the invention. When the piston compresses the air in the cylinder of a diesel engine, its temperature rises significantly. Injection of liquid fuel at the end of the compression stroke leads to its ignition and a sharp increase in the pressure of the working mixture, causing the piston to move in the opposite direction. In this case, the VPD is an analogue of an internal combustion engine or gas turbine engine, but differs from them in that when the air is compressed by a piston, or by a compressor, in an air-steam engine, its temperature rises significantly, and the injection of water, instead of liquid fuel, at the end of the compression stroke, leads to its vaporization and increase in pressure of the working mixture, causing the piston to move in the opposite direction, or causing rotation of the turbine blades, which transmit motion to other mechanical parts. In this case, the VPD uses the heat of compressed air as a fuel and the properties of water to be converted to steam. 1 liter of water gives off about 1600 liters of hot steam at 100 degrees C. The specific heat of vaporization is 2.25 MJ / kg, and the heat capacity of 10 cubic meters of air is 2.52 MJ. It turns out that when 10 mZ of room temperature air is compressed, such an amount of heat is released that is approximately enough to produce 1.6 mZ of steam.

Compressing air in a cylinder or engine compressor up to 100 atm. its temperature rises to 600-700 degrees C. Water at a pressure of 100 atm. increases its temperature only to 311 degrees C. Therefore, the water sprayed by the nozzles in the engine cylinder or in the combustion chamber of the turbine, at a temperature of 600-700 degrees, instantly turns into steam and there creates a somewhat excessive pressure in ι

SUBSTITUTE SHEET (RULE 26) compared to the pressure at the end of the compression stroke. The critical point of water is 374 degrees. C at which the pressure should be about 220 atm. In our case, the pressure at the end of the compression stroke in the cylinder or in the engine compressor is less, which means that a mixture of steam with hot air can perform mechanical work and set the piston or engine turbine in motion. It is not necessary to compare the VPD power with an internal combustion engine or a gas turbine engine, but for low-power consumers this engine will save a certain part of the resources. The power of the VPD directly depends on the temperature of the air entering the engine and at certain minimum temperatures it will not be able to work. VPD can be compared to a solar lens that collects sunlight at one point. It also concentrates the energy of the sun, only dispersed in the air. The use of a heat-insulating motor housing is recommended to maintain and maximize the use of the resulting temperature

Brief description of the drawing. Figure 1. 1 - Cylinder, 2 - Piston, 3 - Air, 4 - Compressed air, 5 - Nozzle. Air enters the cylinder (1), where the piston (2) compresses it. At the end of the compression stroke, nozzles (5) spray water - the pressure rises.

The implementation of the invention. The energy of compressed air has long been widely used in industry and in everyday life. But the heat obtained by compressing the air is usually used less because it is much easier to cool the engines than to use the heat released. The energy of hot steam is also widely used. But, they were not combined (air and steam), probably due to their low joint effectiveness. In modern conditions, with the development of precision engineering, the efficiency of a steam engine can be slightly increased.

In this case, it is possible to use a specialized type of engine running on water (steam) and extracting the required heat from the environment. The energy of the heat of steam was used by the ancient Greeks. Only fuel here is air compressed to such limits until it turns water into steam required for mechanical work. In modern compressors, about 3 kW of energy is released in the form of heat per 1 kW of energy expended - this energy is used by the HPA. But even with an efficiency of 50%, such VPD will be effective and its power can probably be improved over time.

Formula

An air-steam engine is an analogue of an internal combustion engine or a gas turbine engine, but differs from them in that when the air is compressed by a piston, or by a compressor, in an air-steam engine, its temperature rises significantly, and the injection of water, instead of liquid fuel, at the end of the cycle compression, leads to its vaporization and increase the pressure of the working mixture, causing the piston to move in the opposite direction, or causing rotation of the turbine blades, which transmit movement to other mechanical parts.
