Description

 The invention relates to water heating systems and hot water supply and can be used to heat the internal volumes of buildings.

 A well-known boiler installation containing a boiler equipped with a contact air heater and an economizer, connected in parallel to the supply and exhaust lines to the heating paths of the heating network and surface heat exchanger, an air temperature sensor (see USSR AS N 1666855, class F 22 D 1/36) .

 The disadvantage of this boiler installation is the complexity of the design, cumbersomeness, high costs of its manufacture, incomplete use of thermal power.

 The closest is a boiler installation containing a hot water heating boiler with a gas burner, a gas duct, heating and return water pipes, an upper tank with a hot water supply system (see, French application N 2371642, class F 24 H 1/22, 1978).

 The disadvantage of this installation is its low reliability, design complexity, high costs of heat production, incomplete use of the thermal power of a gas burner device, and high hydraulic resistance.

 The objective of the invention is the full use of the thermal power of the gas burner device, cheaper heat production, reduced hydraulic resistance.

 The problem is solved in that the upper tank is made in the form of a cylindrical drum, and the hot water supply system is made in the form of a multi-pass high-speed water-water heater containing bundles of brass tubes separated by chambers at the ends and arranged sequentially from the bottom up.

 The heating surface of the hot water supply system provides 100% use of the power of the gas burner device, i.e. The universal boiler-house installation can be used at 100% use of thermal power both for heating and for hot water supply and in all intermediate modes, for example, 30% for heating, 70% for hot water supply and vice versa, this is the universality of the installation .

 The reduction in hydraulic resistance is achieved due to the location of a large number of brass tubes in bundles (for example, 10 pcs.), Separated at the ends by chambers and arranged sequentially from the bottom up.

In FIG. 1 shows a general view of a universal boiler plant;
in FIG. 2 is a section along AA in FIG. 1.

 The universal hot water boiler installation consists of a hot water heating boiler 1 containing a gas burner 2, a gas duct 3, nozzles 4, 5 of heating and return water, an upper drum 6, in which a hot water supply system is installed, made in the form of a multi-pass high-speed water-to-water heater 7 containing bundles brass tubes 8, separated at the ends by chambers (not shown) and arranged sequentially from bottom to top, through which cold water passes successively through the cold water pipe 9 and hot water comes out through the hot water pipe 10. Heat is transferred to the hot water supply system from the heating water 11 of the heating boiler 1, cold water is supplied at a point 12 located below the hot water withdrawal point 13.

 The universal water boiler installation works as follows. The gas burner 2 burns gas and heats the water - the coolant of the hot water boiler 1, and the exhaust gas is removed through the flue 3. Through the heating water pipe 4, water is supplied to the heating system (not shown in Fig.) And returned to the water return pipe 5 through cooling hot-water heating boiler 1. At the same time, cold water from a hot water supply system mounted in the upper drum 6 can be supplied from a water supply system (not shown) through a cold water pipe 9, sequentially heated vodovodyanyh speed multistage preheater 7 beams brass tube 8 separated by the ends of the chambers, which reduce the flow resistance by the arrangement in series from bottom to top, and used through the pipe 10 with hot water. Heat is transferred to the hot water supply system from the heating water 11 of the heating boiler 1, cold water is supplied at a point 12 located below the hot water withdrawal point 13. Due to the fact that in this boiler 1 priority is given to the hot water system, with 100% use of hot water, heat will not be supplied to the heating system. Accordingly, when the consumption of hot water decreases or ceases, the heating system will receive heat in sufficient quantities of heat consumed by the hot water supply system and will reach 100% when the use of hot water is stopped, which ensures the universality of the purpose of the hot-water boiler plant.

Compared with the prototype of the present invention has the following advantages:
- cheaper heat production;
- full use of the thermal power of the gas burner device;
- reduction of hydraulic resistance due to the arrangement of bundles of brass tubes sequentially from the bottom up;
- increased reliability;
- increase the efficiency of the installation by 12-15% due to the increase in heat transfer surface;
- fuel economy by 15-20%.
