Method for water heating is performed in two-stage boiler: at the first stage of the boiler flow of cooled water after the batteries of heat consumer is supplied by pump for heating, with separation into two flows. The first flow is supplied to circular gaps of the placed concentrically in pairs inner and outer pipes. There heating of water is performed in the mode of surface boiling by gases with high temperature, those move through inner pipes placed in concentric positions. Pressure in compressed space of circular gaps of pipes placed in concentric positions is kept smaller than atmospheric pressure through supply of vapor formed to condenser connected to barometric pipe. The second flow is supplied to the inter-pipe space of the outer pipes of the boiler. Both water flows are after condenser and boiler combined to one and by means of pump it is supplied to the second stage of the boiler for water heating to temperature above 100 DEGREE C, depending on pressure, and after that - to the batteries of heat consumer. |
