  • FIG. 9 PATENIEDHBI 30 ma 3. 768L446 SHEET 4. [IF 4 FIG. 10
  • boiler house of a heating plant is defined as the structure which, in particular, supports and possibly shelters the boiler or boilers.
  • boiler houses and the chimneys are set up in clearly separated buildings or, more rarely, they are close together, as a function of the factors of available surface and esthetics; but in all cases, the buildings are of a different nature and they are necessarily independent.
  • boiler houses may involve a metal structure whereas that of the chimneys is generally masonry.
  • the purpose of this invention is to provide a boiler house and chimney assembly for a thermal power plant which will make it possible to achieve a noteworthy saving, compared to the above-mentioned solutions.
  • the object of the invention is a thermal power plant, especially with a view to the production of electric power, including at least one boiler house equipped with a boiler and at least one chimney for the evacuation of the fumes produced by the boiler, characterized by the fact that said boiler house and said chimney present a common lateral wall portion 'and are made up of a unitary concrete structure.
  • FIG. 1 is an elevation and cross-section view of a first version of an assembly made up of a boiler house and a chimney.
  • FIG. 2 is an elevation and cross-section view of a variation of one version of an assembly made up of a boiler house and a chimney.
  • FIGS. 3, 4 and 5 represent a cross-section view of various versions according to the relative preferential positioning in the assembly of the boiler house towers and the chimneys.
  • FIGS. 6 and 7 show another example of building a boiler house with multiple towers.
  • FIGS. 8, 9 and 10 are plan views of a preferential grouping of an assembly of boiler houses and chimneys.
  • FIG. 1 1 shows a cross-section view of the distribution in a single chimney assoicated with several boilers of several smoke flues corresponding to each one of the boilers.
  • FIG. 1 we have shown one way of setting up the thermal power plant, including the boiler house with a tower l and a chimney 2.
  • a common supporting structure consists of foundations 3 which support a floor slab plate 4.
  • the boiler house and the chimney reveal a vertical portion with a common lateral wall 8.
  • the tower of the boiler house consists of a layer of reinforced concrete 5, with a thickness of about 20 centimeters, surmounted by a belt made of reinforced concrete 6.
  • the tower has a cylindrical revolution shape.
  • the concrete layer of this tower serves as a cover for this boiler house which supports and shelters the boiler as such, which is not shown here.
  • the tower of the chimney as such consists of a revolution cylinder of reinforced concrete 7 with a thickness of about 30 centimeters.
  • a smoke flue 9 is ranged concentrically inside the chimney while leaving a free space 91 between the chimney and the flue.
  • This flue which in our example here is made of metal, is designed to protect the concrete of the chimney against heat stress, that is to say, against the chemical attack of hot gases; the free space guarantees heat insulation and at the same time permits any possibly necessary maintenance or repair work.
  • FIG. 2 we have a variation where the boiler tower is shown at 1 while the chimney 2 involves, on the one hand, a smoke flue 71, starting at the upper portion of the tower of the chimney through a collector 72, and, on the other hand, a lower flue 73.
  • the evacuation of the smoke from the chimney is directed toward its upper part and only the upper part of the chimney is useful for the evacuation of the smoke.
  • the lower portion of the chimney thus becomes available for technical uses, such as staircases, freight elevators.
  • the height of the smoke flue is reduced by the height of the lower flue which enables us to achieve a further considerable saving.
  • FIG. 3 we have thus shown a chimney tower 2, supported externally against a boiler house 1, which constitutes the simplest version, but which occupies a larger ground surface.
  • the boiler house would not necessarily be made up of a single closed concrete cover, especially in the case of out-door construction.
  • FIGS. 6 and 7 we have thus shown, respectively, an elevation view and the horizontal cross-section of one particular way of construction according to the invention, where, in an outdoor construction, the boiler house consists of an assembly of four posts 2, 2A, 2B, 2C and constitutes the chimney as such, while the three others can be set aside for technical uses, other than the evacuation of smoke, and in particular for storage purposes, especially fuel or water.
  • FIG. 8 we have shown a general model of a thermal power plant consisting of two boilers l0 and 20, combined according to the invention with their chimneys 2 and 2, the units being set up opposite each other.
  • FIG. 9 which shows a variant compared to FIG. 8, we place in one special version of the inventon a common chimney 2 between the two boilers l0 and 20, so that the axis formed by boiler 10, the common chimney, and boiler 20 will be laid out parallel to the facilities in engine rooms 11 and 21, on the one hand, and the zone of generators 12 and 22, on the other hand.
  • FIG. 10 we have shown one particular version of constructing a thermal power plant according to the invention, with four boilers 10, 20, 30 and 40, associated with a single chimney 2.
  • Boiler rooms 11 and 21 are juxtaposed so as to face along with the common control room 23 the boilers 10 and 20, while boiler rooms 31 and 41 are juxtaposed so as to face, along with common control room 24, the boilers 30 and 40.
  • the zones of generators 12 and 32 are juxtaposed so as to face the boilers l0 and 30, while the zones of generators 22 and 42 are juxtaposed so as to face the boilers 20 and 40.
  • FIG. 11 we have shown a cross-section view of a chimney 2 and metal smoke flues 92 and 93, associated with two boilers, not shown in the figure, and surrounded by free spaces 94 and 95 with a width on the Order Of 6Qnt mtrs Independently of the heat insulation of the reinforced concrete of the chimney, the subdivision of the flues enables us to ensure the independence of the draft of the smoke from each one of the boilers and their independent maintenance.
  • the chimney was divided into two circular sectors but it is evident that it can be divided into a larger number of circular sectors, for example, three or four.
  • a thermal power plant including at least one boiler house said boiler house having a boilerand at least one chimney for the evacuation of the smoke produced by the boiler, the improvement comprising: a common lateral wall forming an integral part of said boiler house and said chimney, said boiler house and said chimney being made up of a unitary concrete structure integrally with said common lateral wall.
