The invention relates to the field of power engineering and can be used in the circuits of the heating boiler.

Known counterparts - heating boiler rooms containing boilers, connected between the feedback and the feed network of the pipelines included in the feedback network pipeline network pump, parallel to the pipeline recirculado network pipelines (see kN. Ionina A. A. and other Heat. - M.: stroiizdat, 1982, Fig. 12.6, S. 282), chemical water treatment apparatus, the deaerator (usually vacuum) with connections to the source of deaerated water and the heating agent (when using the vacuum deaerator - hot water), the water-tank and the pump make-up water, connected by piping make-up water from the reverse pipeline network (see Fig. 14.1, S. 313). This analog adopted as a prototype.

The disadvantage of analogs and prototypes is reduced, the reliability and efficiency of the boiler due to the complexity of the scheme and of low quality deaeration of makeup water.

The aim of the present invention is to improve reliability and efficiency of the boiler by simplifying the scheme and improve the efficiency of deaeration of makeup water.

Proposed to achieve this result, the heating boiler provides hot water boilers, connected between the feedback and the feed network of the pipelines included in the feedback network pipeline network pump, parallel to the recirculation piping with recirculation pump and regulator and regulating the jumper connecting the back and hearth (hot water) and water-tank. Boiler is characterized by the fact that the recirculation piping and regulating the jumper is connected to the reverse pipeline network to network pump, regulating the jumper included booster pump in the recirculation piping included vacuum deaerator so that the nozzle of a heating agent connected to the recirculation pipe to the supply network pipelines, tank battery vacuum deaerator connected to the suction inlet of the recirculation pump, the regulator on the recirculation pipe is located before the inlet of the hot water vacuum deaerator.

A new set of features allows to simplify the design of the boiler and thereby improve the reliability and efficiency of the boiler, and also to provide a vacuum deaeration in the high temperature mode by skipping through the deaerator flow recirculation water that contributes to the efficiency of the vacuum deaeration.

The drawing shows a partial schematic diagram of a heating boiler which provides hot water boiler 1 with attached feed 2 and back 3 network pipelines. In the reverse pipeline network 3 enabled network is not recirculated by the pump 6 and the regulator 7, and regulatory jumper with 8 booster pump 9. The pipeline 5 and the crosspiece 8 is connected to the feedback network line 3 along the water to the pump power is 4. In the recirculation pipe 5 includes a vacuum deaerator 10 with connections to the source 11, superheated 12, deaerated 13 water and water-tank 14. The hot water pipe 12 connected to the recirculation pipe 5 to the supply network pipe 2 through a regulatory body 7. Tank battery 14 of the tank 10 is connected with the suction inlet of the recirculation pump 6.

Heating boiler works in the following way. Reverse network water enters the hot water boiler 1, where it is heated to a temperature of about 150oC, then the water enters the feed pipeline network 2. Source water after treatment were fed into the vacuum deaerator 10, from the vacuum deaerator 10 water enters the water-tank 14, from which the recirculation pump 6 is fed in the reverse network line 3 where it mixes with the feedback network water, and then a network pump 4 is fed into the boiler 1. To regulate the water temperature in the supply pipeline network 2 is the mixing of colder water from reverse is there a network of water from the pipeline 2 with a temperature of approximately 150oC is bypassed through the regulatory body 7, the tank 10, tank battery 14 and the recirculation pump 6 in the reverse pipeline network 3 to maintain the required (usually 70-90oC) water temperature before the boiler 1. Simultaneously, the water, return the fulfilled through the deaerator 10 for recirculation, is in the deaerator heating agent that enhances the quality of air by increasing the temperature regime of the deaeration process.

Novelty and significance of the differences between the claimed solution is attributed to the new relationship of the elements of the boiler: connecting the recirculation piping and regulating the jumper to the pump power, the inclusion in regulatory jumper booster pump, turning on the vacuum deaerator with a water-tank in the recirculation piping between the regulator and a recirculation pump.

Heating boiler containing water boilers, connected between the feedback and the feed network of the pipelines included in the feedback network pipeline network pump, parallel piping recirculation with recirculation pump and regulator and regulating the jumper connecting the feedback and the feed network pipelines, the jaś fact, the recirculation piping and regulating the jumper is connected to the reverse pipeline network to network pump, regulating the jumper included booster pump in the recirculation piping included vacuum deaerator so that the hot water pipe connected to the recirculation pipe to the supply network pipelines, tank battery vacuum deaerator connected to the suction inlet of the recirculation pump, and the regulatory authority on the recirculation pipe is located before the inlet of the hot water.
