摘要:
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.

The invention relates to a thermal energy recovery unit in connection with a furnace of a building, comprising a flue duct (110) for conveying flue gas released from the furnace. The recovery unit comprises a liquid container (120) arranged around the flue duct (110) for collecting thermal energy in the flue gas conveyed in the flue duct into the liquid in the liquid container (120), and at least one liquid connection (101, 102) for connecting the liquid container (120) of the recovery unit to another recovery unit so as to enable transfer of the liquid in the liquid container between the recovery units.

A cooling device for fume intakes for exhausted gases from foundry furnaces comprises a flue pipe for extracting the fumes produced in premises containing a source of fumes, a cooling system consisting of a tube (3) made of steel lined in appropriate areas of its surface and length and wound in a spiral. In the tube (3) there circulates cooling water with a temperature of the water at entry and in operation kept constantly between 50 and 120°C, with a temperature variation between the inlet (4) and the outlet (5) of the tube (3) in a range of 10-30°C. The lining of the tube (3) may be made of special martensitic stainless steel, or of glassy alloy, or of Ni/Cr cermet.

A device for cleaning of flue gases through condensation in small scale firing with fuel pellets having a substantially vertical glue gas cooler (12). The flue gas cooler (12) comprises an inner (4) and an outer (3) pipe, being substantially mutually concentric, arranged with a space (2) between them in a radial direction. In the space between the inner (4) and outer (3) pipe there is a helical pipe (5) for a flowing cooling medium. The flue gases are led through the space (2) between the inner (4) and outer (3) pipe for cooling and condensation. A method for cleaning of flue gases in small-scale firing with fuel pellets comprising the steps of leading the flue gases into a space (2) between an inner (4) and outer (3) pipe, which are mutually substantially concentric and having a helical pipe (5) arranged in the space (2) between the inner (4) and outer (3) pipe, cooling of the flue gases to condensation, partly so that the condensate forms a liquid film or droplets on cooled surfaces (5), and partly so that the condensate forms droplets falling freely in the flue gases, whereupon the condensate water is collected and remaining flue gases are led out of the space (2) between the inner (5) and outer (3) pipe.

摘要:
To be interposed in a flue, a water heater comprising inner and outer peripherally-interspaced tubular members (11, 10). The inner members (11) projects at both ends beyond the outer member (10) and is dimensioned for fitment between and integration with spaced and mutually-adjacent ends of axially-aligned flue sections (18, 19A). Walls (13,14) bridge directly between the ends of the outer member (10) and the periphery of the inner member (11) and sealed to both thus to define a peripherallycon- tinuous watertight chamber (12) between the two members (10, 11). Three parallelly spaced watertight tubes extend between openings in the inner member (11) and fitted therein in sealed relation with the peripheries thereof whereby the tubes participate in water circulation with the chamber. Nozzles (20) adjacent to opposite ends of the outer member (10) provide for integration of the chamber and tubes into a water circulation system.

The invention relates to a heat recovery chimney (10) which comprises a flue pipe (11) for connection to a fireplace and a jacket pipe (12) fitted around the flue pipe so that the flue pipe (11) and the jacket pipe (12) delimit an annular water space. The water space is closed by end pieces (16) at both ends in the direction of the length of the chimney (10) to form a closed space. Heat-storing fluid is circulated in the water space and receives heat produced by flue gas directly from the flue pipe (11), from which fluid the heat is arranged to be utilized. A flow channel (13) is fitted inside the water space of the heat recovery chimney (10) and extends substantially from the bottom end of the water space to the top end thereof, to one end of which flow channel an inlet coupling (17) is connected to supply circulation fluid to the flow channel (13). The circulation fluid is discharged through the opposite open end of the flow channel (13) into the water space from which it is utilized through a fluid outlet coupling (18) connected to the jacket pipe (12) at the same end of the water space in the direction of the length of the heat recovery chimney (10) as the inlet coupling (17).
