The invention relates to a power system, namely the use of heat of flue gases of boilers for heating water supplied to the consumer.

The disadvantage of this system is the low efficiency of the use of flue gases due to the fact that the system uses an intermediate heat transfer fluid, radiating heat is not directly water, and gas (e.g., helium). Warm gas is given through the converted mechanical energy, which rotates the rotor of the generator. In this scenario, you experience a loss of energy to friction. In addition, the necessary additional power consumption for the cooling of the Stirling engine and the pump for supplying water in the fridge. In the known system there is no centralized automated control system.

Heat exchanger is necessary to maintain the water temperature is 100°C. if this temperature is not maintained, water is directed to the contour recycling machine�recyling. In this regard, it is impossible to maintain the required for the user work flow. Furthermore, the known system cannot regulate the speed of movement of flue gases through the heat exchanger to regulate the temperature of heating water, and create force exhaust flue gases through the chimney. In the known system does not contain the design of the heat exchanger, heating water, flue gases, whereby it is impossible to determine the efficiency of heat exchange, and no centralized automated control system.

The coil 8 is made of a material having high thermal conductivity, for example of brass. To the entrance of the coil 8 is connected to the input tubing 16 of the flue gases of the boiler plant. At the outlet of the boiler system can be installed strainers (Fig. not shown). To the output of the coil 8 connected to the output conduit 17.

In tank 1 coil 8 is installed with the possibility of taking. On the inner surface of the coil 8 are deposited solid fra�tion of flue gases. To clean the coil 8 on the inlet and outlet of the coil 8 mounted device for doffing 22. The main requirement for the device 22 for removal of the coil 8 to ensure a tight seal.

The tank 1 is connected with a circulating pump 23, an adjustable control device 24, via a conduit, comprising a temperature sensor 25, the flow sensor 26, the pressure sensor 27. The circulation pump 23 through an adjustable control device 28 of the valve 29 is connected to a recirculation conduit for supplying water to the tank 1.

The flue gases from the boiler plant flowing into the water heating system, pre-pass through the coarse filter (Fig. not shown). Further, the flue gases from the boiler plant is received in the coil 8 located in the tank for heating water 1, through the inlet flue gas duct 16 by the vacuum created by blower fan 18. To regulate the modes of operation of the blower fan 16 can be used the device to control its operation 20. Passing through the coil 8, the flue gases heat the water in tank 1. Heating the water in tank 1 is uneven due to the cooling of the flue gas when driving coil 8. To increase the heat transfer from the flue gas of the heated water in the tank 1 is installed propeller stirrer 0, rotating due to the operation of the control device is a propeller stirrer 11. For mixing water in the tank 1 instead of a propeller stirrer 11, or in conjunction with it, can be mounted a pneumatic stirrer water (Jacuzzi) 12.

To control the modes of operation of the blower fan 19 may be used in the control device 21.

Heated in the water tank 1 is pumped from the reservoir 1 through the circulating pump 23, which is driven by a device�istom control 24. The temperature sensors 25, 26 and flow pressure 27 are controlled by the parameters of the pumped water. If the parameters of the pumped water does not meet the required, through an adjustable valve 29 controlled by the control valve 28, the water re-enters the pipe 2 for supplying the reservoir 1. If the parameters are pumped from the reservoir 1 water meets the required, it is adjustable via the valve 31 controlled by a control device 30 is supplied to the mixing chamber 32. From the mixing chamber 32, the heated water is supplied to the consumer, for example, in mine air heater installation. Depending on the required flow rate and temperature of the heated water to work the mine air preheaters she can only be fed from the tank for heating water 1 or in the mixing chamber 32 will additionally come direct water from the boiler plant, the parameters of which will be measured by the temperature sensors 35, 36 and flow pressure 37. The work is regulated by the valve 39, the control valve 38 and a network of pump 43, the performance of which is regulated by the control unit 44 will be determined depending on the parameters (temperature and pressure) and water required for operation of the mine air preheaters its flow. Supply direct water from the boiler plant is installed adjustable�ow valve 34, controlled by the control valve 33. The parameters of direct and return water is controlled by the temperature sensors 40, 45, flow 41, 46 and pressure 42, 47.

The water in the tank for heating water 1 is replenished from the source of water supply which may be industrial water, artesian wells, etc. need to replenish the reservoir 1 is controlled by a level sensor 9. In the case where the temperature of the water in the tank 1 is sufficient for feeding into the mixing chamber 32, the valve 29 is closed by means of a control valve 28 and the valve 31, by means of a control valve 30 opens. When the water level in the tank 1 becomes minimum, the valve 31 is closed and the reservoir 1 with water fed from a water supply source via a managed device 3 of the valve 4. The parameters of the water flowing from the water supply to the tank 1, are controlled by the temperature sensors 5, flow 6 and pressure 7. During the period of filling the tank 1 with water from a water supply source in the mine air heater installation water will flow from the boiler plant.

FIELD: heating systems.

SUBSTANCE: method comprises control of temperature of at least one of secondary flows of fluid in the secondary circuit which outflows from heat exchanger (1) by means of the primary flow in the primary circuit with the use of control members (5) and (11) that control the primary flow under the action of control unit (7), determining the difference of enthalpies of the primary flow that enters heat exchanger (1) and primary flow that leaves heat exchanger (1), measuring the secondary flow, measuring the flow in the primary circuit, and sending the parameters determined to control unit (7) for control of control members (5) and (11). As a result, the primary flow is controlled by the secondary flow so that the power supplied to the heat exchanger with the primary flow is, in fact, equal to the sum of the power required for the heating of the secondary fluid from the initial current temperature up to the specified outlet temperature, power required for the compensation of energy stored in heat exchanger (1), and power losses from heat exchanger (1). The description of the device for control of water temperature is also presented.
