The invention relates to the field of heat power, namely the power plant with engines structurally combined with boilers, and can be used on boiler units in the production of hot water and at the same time to drive a variety of devices, such as generators, conveyors, pumps.

Known steam turbine with a working body in the form of a rotor and a continuous work process that converts into mechanical kinetic energy of the rolling of the working fluid pair. Steam turbine used in thermal power plants to drive generators, centrifugal compressors, nutrients, fuel, oil pumps [Losev S.M. Steam turbine and condensing device. Theory, design and operation. M. - L.: 1964, Shahlaei L.V. Theory of thermal process and design of turbines. M. L. 1967].

Practice operation of steam turbines shows that with the power increase their efficiency increases and decreases the cost of the energy produced. Accordingly, the turbine of small capacity are not implemented due to unsatisfactory performance efficiency and cost.

Known hot-water boiler with natural circulation of water, consisting of a boiler, the heated flue gases and intended for heating water is, under pressure above atmospheric and is used as the coolant outside of the device; valves; furnaces [Stotsky LR "the Engineer (fireman) boiler on liquid and gaseous fuels". ISD "Nedra", 1975].

As a prototype of the selected technical solution, including formed by the walls of the combustion chamber with a drum and nutrient capacity, connected to the drum, while the combustion chamber is in the form of a water jacket connected to a nutrient tank with the formation of the circulation circuit (RF patent No. 2024790, CL F 22 21/00, 1991).

In the known technical solutions, the water circulates, like any moving body possesses kinetic energy that can be used to make mechanical work, which is not the case at present.

A disadvantage of the known technical solutions is the fact that the kinetic energy of moving water is not used to perform mechanical work.

The objective of the invention is to expand the functional capabilities of the device.

The technical result, which is aimed invention is to provide opportunities for the use of the kinetic energy of boiling water to perform mechanical work, such as drive current generators, transport is s, the pumps.

The technical solution is ensured by the fact that according to the first variant of the engine boiling containing the combustion chamber, dryer, feeder, connected to the drum, collector, while the furnace drum combined in a single metal enclosure with one removable wall, the axis of the drum is placed horizontally inside the drum is a working body in the form of a shaft, the ends resting on the bearings installed in the center of each wall of the casing from the inner side of the horizontal axis on a shaft parallel to the axis of the fixed plane of the blades and the gear wheel, and the blades are made in the form of metal plates, between which are mounted a metal septum, forming a symmetrical axis of a circular tank filled with air from the outside of the drum is parosbornoj.

According to the second variant of the engine boiling containing the combustion chamber, dryer, feeder, connected to the drum, collector, while the furnace drum combined into a single metallic case, with the axis of the drum is located vertically in the center of the bottom and inner side of the cover is installed the bearings inside the drum is a working body in the form of a shaft, the ends resting on the bearings on the shaft at an angle to the axis of the fixed square is Scoti blades in the form of a screw, around the shaft symmetrically to its axis made a circular tank filled with air, near the drum is a collection of hot water, reported to him on the overflow at the top and the collector at the bottom.

In the engine boiling the working fluid is steam-water mixture. The engine boiling is further provided with an actuating mechanism located on the outside of the drum.

General view of the device represented in figure 1 and 2 (option).

The engine is boiling, figure 1, consists of a drum 1, the removable wall 2 boiler 3, the combustion chamber 4, the blades 5, the annular cavity 6, the gear wheel 7, the actuator 8, parosbornoj 9, the discharge pipe 10, the feeder of the boiler 11, the economizer 12.

The engine boiling works as follows.

The drum 1 of the engine is divided conventional vertical and horizontal planes intersecting in the Central part of the drum, into four sectors. In the I-th sector, outside drum, made the heater 3 from the piping system, which receives heat from the combustion chamber 4. Boiler 3 intensifies the boil, and then increases the speed of circulation of water in the drum. With the beginning of the boiling water in the I-m and II-m sector it ceases to be uniform, into the steam-water mixture, which because of the bubbles to the increased volume. In the III-th sector, outside Baraba is a 1, is metal parosbornoj 9, which has a larger volume compared to other sectors. Here comes from the second sector of the steam-water mixture. In pasborice 9 ends in boiling water, it takes the initial state.

Since the inside of the drum causes rotational movement of the water, then it operates by centrifugal force, and therefore, the device can operate as a centrifugal pump.

To do this, in the IV-th sector, outside of the drum, along the tangent to the generatrix of the inner surface is the discharge nozzle 10. With this pipe hot water is supplied to consumers and the feeder to the boiler 3. The heater 3, the first and the second sector of the drum comprise a lifting of the engine; III, IV the sector, the discharge nozzle 10, the feeder of the boiler 11 and lowering of the engine.

When operating, the drum 1 is filled with hot water.

Because of the constant rise of the bubbles of steam with the water up in the II-th sector produces a higher level relative to the level of the third sector, so the water will move from the II to the III-th sector. So inside the drum is a circular movement of water. Like any moving body of water has kinetic energy, which is determined by the formula

Ek=mV2/2, where

Ek - kinetic energy of water;

m is the mass of water;

V is the velocity of translational motion of water.

rugosae movement of boiling water perceives the working body by means of the blades 5 and by means of toothed wheels 7 transmits this movement to the Executive mechanism (generator) 8.

The economizer 12 uses the waste heat after heater 3 for heating return water.

The annular cavity 6 is filled with air to create a buoyancy force that balances the force of gravity working body, reduces friction in the bearings. The bearings are immersed in water, which for them with grease.

The engine is boiling on the second version contains the drum 1, the collection of hot water 17, the cover 15 of the drum, the bottom 13 of the drum, the heater 3, the combustion chamber 4, the blades 5, the annular cavity 6, the bearings 14, the actuator 8, overflow 16, water manifold 18, the feeder of the boiler 11, the economizer 12.

When operating, the drum 1 is filled with hot water. From the furnace chamber 4, heat is transferred to the boiler 3 and heats the bottom 13 of the drum, on its inner surface formed vapor bubbles, which operates the pushing force directed vertically upwards. Under the action of this force the bubbles begin to rise up and lead in the same direction areas of water that are in their way. In place of the bubbles of steam and water, which rose from the bottom 13 of the drum at its upper part, receives a portion of the water from the collector 17.

Because of the constant rise of the bubbles of steam with the water from the bottom of the drum in the upper part of the water level in it increases and reaches the overflow 16, permeke is the collection of hot water 17.

The movement of boiling water perceive the blades 5, is the rotation of the shaft, the transmitting movement of the actuator 8. The economizer 12 uses the waste heat after heater 3 for heating return water.

The shaft has a sealed cavity 6 is filled with air. It serves to create a buoyancy force that balances the force of gravity working body, and therefore reduces the friction in the bearings.

The bearing on the bottom immersed in water which is grease.

This solution can be used in the production of hot water and at the same time to drive a variety of devices, as well as a centrifugal pump.
