The invention is intended for heating the coolant and can be used in heat power engineering. The heat generator contains a furnace, a lower screen made in the form of a flat spiral, lower and upper ring collectors, vertical collectors and heating surfaces, including convective ones, made of a flat spiral. All the ends of pipes of heating surfaces are put in vertical collectors. The invention provides increased reliability and efficiency.
DESCRIPTION OF THE INVENTION
The invention relates to heat power engineering and can be used, in particular, for the design of boilers operating on all types of fuel and for use in housing and communal services, agriculture and industry.
Known device for as. 324448 (published on December 23, 1971) , comprising a cylindrical body, radiating and convection heating surfaces and a partition wall arranged in parallel therein, the dividing wall being made with the same radius as the body and being offset with respect to the longitudinal axis of the steam generator, And the convective heating surfaces are made in the form of flat coils installed parallel to the longitudinal axis of the steam generator.
The disadvantage of this design is the large volume of machining of the collectors, which complicates the technology of manufacturing the boiler.
From this disadvantage, a water-tube boiler is available. 959909 (published on 09/09/82) , which is a vertically installed heat exchange pipe connected to the upper and lower manifolds, each collector being made of a flat spiral.
The disadvantage of such a boiler is the non-technological nature of this design , the complexity of assembly, operation, repair, inefficiency in operation, and reduced maintainability, because Radial sections of the tubes at the places of their connection with the collectors are close to each other, which makes it difficult to access them.
The closest analogue is the promotion boiler according to the patent 2057985 (published on April 10 , 1996) containing a furnace, a heating surface including horizontal flat tubular spirals, and vertical spiral coils, moreover it is provided with an economizer made in the form of a pack of spiral coils connected to three Vertical collectors, one of which is a supporting one, and the heating surface is made in the form of three horizontal flat tubular spirals and three vertical coils communicated with the economizer through the support manifold.
The disadvantage of this boiler is the non-technological nature of this design, the complexity of assembly, operation, repair, inefficiency in operation.
The proposed invention solves the problem of creating a reliable and efficient heat generator, simplifying the assembly, operation and repair.
In order to achieve this technical result in a heat generator comprising a furnace, a screen, vertical collectors and heating surfaces, including convective ones made of a flat spiral, whose pipe ends are inserted into said vertical manifolds, it comprises a lower and upper ring manifolds, said screen being lower and Is made in the form of a flat spiral, and all the ends of the pipes of the heating surfaces are inserted into the said vertical collectors.
Distinctive features of the proposed structure from the above, closest to it, are that it contains the lower and upper annular collectors, said screen being lower and made in the form of a flat spiral, and all the ends of the pipes of heating surfaces are inserted into said vertical collectors.
Thanks to the presence of these features, the efficiency and reliability of the heat generator in operation is increased, the technology of manufacturing boilers, their assembly, operation and repair is simplified.
The proposed heat generator is illustrated in FIG. 1 and FIG. 2. FIG.
 FIG. 1 shows a general view of the heat generator in isometric view (skeleton conditionally removed) |
 2 schematically shows a tubular unit |
Constructively, the heat generator has a frame (1) consisting of a lower annular collector (2), an upper annular collector (3) and three vertical collectors: input (4), intermediate (5) and output (6). The heating surfaces are made and are recruited from three types of elements: volumetric spirals (7), flat spirals (Archimedes spiral) (8), one of which is the bottom screen, and a burner belt (9), all the ends of the heating surface tubes being placed in vertical collectors , Combining the lower and upper ring collectors. In this case, the input manifold (4) and the industrial collector (5) are separated from the upper annular (3) washers with a diameter of 5 mm, and the output collector (6) and the industrial collector (5) are separated from the lower annular (2) washers with a diameter of 10 mm. This separation provides a general circulation principle (lower annular - input - industrial collector - outlet upper annular) air outlet and water discharge from the boiler.
The heat generator operates according to the principle of a boiler with a burner installed in the burner belt, a firebox enclosed by screens of volumetric spirals (7) and a gas flue in the upper part of the structure with the release of gases in its central part.
Combustion products from the furnace pass a convective beam (flue) and transmit heat to the working medium circulating through the pipes. The water is supplied by a mains pump to the annular collector and passes through the vertical collector through the burner belts to the intermediate collector, then water is distributed from the intermediate manifold to 3 volumetric (7) and 5 flat spirals (8), then the heated water exits through the outlet into the upper annular collector .
By simplifying the design of the heat generator, the technology of manufacturing boilers, their assembly, operation and repair is simplified. In the heat generator, the heating surface increased, which led to efficient heating of the coolant, weight-and-size characteristics improved, and so on. Increases the reliability and efficiency of the heat generator in operation.
CLAIM
A heat generator comprising a furnace, a screen, vertical collectors and heating surfaces, including convective ones, made of a flat spiral, the ends of which are inserted into said vertical collectors, characterized in that it comprises a lower and upper annular collectors, said screen being lower and executed In the form of a flat spiral, and all the ends of the pipes of the heating surfaces are inserted into the said vertical collectors.
