(57) The purpose of the invention is the design (construction) of the flue (1) of the
solid fuel boiler system. The design which causes the effect of turbulence in the
flue and at the same time is easy to disassemble and clean. It consists of the following:
the inlet (2), the flue channel (3), the turbulence plates (4), the heat exchanger
(5), the free passage (6), the outlet (7), and the inspection aperture (8). The main
distinctive feature is the turbulence plates (4), which consist of the following structural
elements: the bottom support (9), two upper supports (10), the body (11) and the notch
(12). The said turbulence plates are called turbulence because they force gas (fumes)
to stop itself in the flue, to rotate, and to flow around the obstacle. In boiler
flue these plates are installed at a certain angle and stop the outgoing fumes; the
latter spend a longer time in the heat exchanger and give a larger amount heat to
it. In the design of the invention the aforementioned turbulence plates are not able
to "burn" as they touch the small surface of the flue, also they are much easier to
clean. The design of the invention is particularly well suited for solid fuel gas
generation boilers, however it is also suitable for all equipment of the solid fuel
boilers of the bottom and side combustion.
