  • Patent number: 8257034
    Abstract: A radial fan comprises a casing having a side portion and a pot-like casing portion, an impeller wheel arranged therein and having radially extending blades, an electric motor arranged at the side portion, and a pressure chamber which is formed by the casing portion and the side portion. The pressure chamber with the impeller wheel space between the blades forms in cross-section a nozzle in the manner of a venturi nozzle. The ratio of the greatest blade height H/greatest diameter D of the scroll is substantially between H/D=0.08 and H/D=0.3.

  • Patent number: 8109731
    Abstract: A radial fan impeller has the following features: a plurality of blades distributed around the periphery; viewed in the radial direction, the blades extend from an inner inlet region to an outer discharge region; the blades extend axially, viewed in the direction of a rotation axis, between an inlet side and an axially opposite hub side; on the inlet side, the blades are connected by means of their radial extension as far as the discharge region to a covering disc which has a central inflow opening, opening out into the inlet region; on the hub side the blades are only connected with their radial inner end regions to a central hub; the blades and the covering disc define an outer fan impeller diameter which is at least ten times an axially measured flow discharge width of the blades provided in the discharge region.

  • Patent number: 7922481
    Abstract: The temperature generated by a firing apparatus, particularly a gas burner, depends on the mixing ratio between the quantity of air and the quantity of gas fed to the firing apparatus, characterized by the excess air coefficient ?, at a predefined burner load (air mass flow rate) in such a way that the temperature generated by the firing apparatus reaches a maximum when ?=1. According to the inventive method for adjusting the excess air coefficient, said maximum temperature Tmax is determined, whereupon the desired setpoint value ?hy of the excess air coefficient is adjusted and the associated setpoint temperature Tsoll is measured. A characteristic curve which represents the correlation between the respective air mass flow rates and the setpoint temperatures at the setpoint value ?hy of the excess air coefficient and allows combustion to be regulated to an optimal hygienic state can be determined from said determined correlation between the setpoint temperatures Tsoll at different predefined burner loads.
