摘要:
A gas-fired condensing convector or convector/radiant room heating appliance comprising a sealed combustion chamber 12 communicating with a baffled heat exchanger 21, a gas burner 13 within the chamber 12 fed with forced or induced air for combustion from a toroidal air blower 16, a convector fan 25 for circulating air over at least the heat exchanger, and a small bore flue pipe 24 terminating in a two-way outlet terminal means for the discharge of waste gases and liquid condensate. The thermal efficiency of the appliance is at least 90% and the temperature of the waste gases is below the dew point and at less than 50°C.
摘要:
A bidirectional flow system for a cooking oven is provided. The flow system comprises: an oven chamber (26) having a first cooking zone (82; 182) in fluid communication with a second cooking zone (84; 184), the oven chamber having at least a floor, a ceiling, and a mezzanine (48, 80; 148; 180) for dividing the first and second cooking zones (82, 84; 182, 184); a gas circulation system (24) for supplying gaseous cooking medium initially to either of the first or second cooking zone; and a return assembly (32) for receiving returned gaseous cooking medium, wherein the return assembly includes a plurality of louvers (40, 42, 44, 46) movable between a first position and second position to receive returned gaseous cooking medium from the other of the first or second cooking zone. A method of cooking during a cooking cycle by changing flow direction of gaseous cooking medium in a cooking oven chamber is also provided.
摘要:
A heating apparatus (1) including a rear wall with an opening (6) provided with an edge (41) spaced apart from the edge (40, 40', 40") of the rear wall (2), and having a standard size predetermined according to the power of the heating apparatus but not according to the apparatus type or the fuel used therein, as well as an intermediate member (7) having a standard shape selected according to the fuel used, and being fitted in said standard opening (6) for sealing same, said member having a through-hole (8) enabling communication between the inside of the heating body and the flue gas outlet, optionally via flue gas discharge means.
摘要:
The device is intended for fitting in an essentially horizontally running part of the discharge pipe for flue gases and has the form of a T-shaped pipe section (5) with the centre leg (8) of the T pointing downward, said leg (8) serving to discharge the condensation which has collected in the discharge pipe downstream of the device, whereby in the inner side of the horizontal legs (6, 7) of the T (5) there is a deflecting flange (9) for the condensation, situated opposite the vertical leg (8) of the T (5).
