Abstract

The invention relates to a power system and can be used in heating boilers. The purpose of the invention is to reduce energy consumption by reducing aerodynamic drag and ensuring uniform heat exchange. The boiler contains a shielded radiation chamber 1 with burner devices and a convection chamber 2 with heat exchange elements made in the form of pipes 3 connected to vertical columns 4 mounted inclined to the vertical axis of chamber 2 and symmetrically relative to the latter. When the ratios of the flow area, respectively, of the inlet and outlet sections 5,6 of chamber 2, are equal to 2.5 ... 2.75, the aerodynamic resistance reaches its minimum value, which reduces the electric power consumption for the blast. 1 hp f-ly, 2 ill.

The invention relates to a power system and can be used in heating boilers.

The purpose of the invention is to reduce consumption

coming into the gap through the perforated sheet 9 of the air channel. The mixture that forms with the gas-air is burned in chamber 1, while the products of gas combustion transfer heat

the products of gas combustion enter the convection chamber 2. The vertical sinks 4 are flushed with pipes 6 of heat exchange elements at a constant speed, the products of combustion, giving off heat by convection to pipes 3,

of electricity by reducing aerodynamic radiation to screens 12 and 13. From the chamber 1

heat transfer uniformity.

FIG. 1 shows a water boiler, a longitudinal section; in fig. 2 shows section A-A in FIG. one. , ,

The boiler contains radiation cooled chambers going through the hog to the chamber 1 with chimney burners (not shown). and a convective chamber 2 with heat transfer, with respect to the areas of passage

elements made in the form of pipes of the inlet section 5 and outlet 6 of sections 3 connected to vertical stands 4, 2.5-2.75, the smallest value located along the flow from the input 5 of the boiler’s aerodynamic resistance, section 5 to the output section 6 of the convection chamber 2 with a slope to its vertical axis and symmetrically with respect to the latter. The area of the flow section of the convective chamber 2 decreases along the gas flow, and the ratio of the areas of the flow area of the input 5 and output 6 sections is 2.5-2.75. The gas-burning device consists of a cylinder 7, a gas collector 8 and a perforated sheet 9. The distance

between adjacent pairs of sinks 4 in any 25th of the electric power by reducing the aero-horizontal cross-section the same. The radiodynamic resistance, the ratio 1 and the convective 2 chambers of the enclosures of the entrance section and the walls are nonexistent. In the radiation chamber 1 of the exit sections is 2.5-2.75. partition 1 installed, separating

convection chamber 2 from radiation 2. The boiler according to claim 1, characterized in that

chambers 1. The radiation surface of the heater to ensure uniform heat transfer of the chamber 1 consists of vertical screens, heat exchange elements are made in
