Abstract: A burner structure and a method of operating a burner to reduce the pollutant emissions produced thereby are disclosed. Air and gas are premixed in a manner such that a substantially homogeneous mixture containing excess combustion air results. The velocity of the substantially homogeneous mixture is increased as it passes through the burner causing the "residence time" associated with the formation of the flame to be decreased, i.e., the combustion gases are in the reaction zone of the flame for a significantly shorter period of time, reducing the production of NO.sub.x. In order to prevent the flame from "lifting-off" the burner because of the high velocity of the substantially homogeneous air/gas mixture, flame stabilizing devices and/or a burner structure which provides flame stabilization are utilized resulting in the production of a high heat flux and low pollutant emissions.

Abstract: A combustion of the present invention has a burner, a combustion fan supplying air to the burner, revolution rate detection means for detecting a revolution rate of the fan, and an air-flow rate sensor for detecting an air-flow rate of the air. The combustion device further has a temperature sensor for detecting a temperature at the combustion device and diagnosis means for performing a self-diagnosis to determine a ventilation condition based on a relationship between the revolution rate and the air-flow rate. The diagnostic means correct the detected revolution rate or the air-flow rate based on the temperature of the combustion device in the process of performing the self-diagnosis. The diagnosis means perform the self-diagnosis after a predetermined time has passed until there is no temperature variance in the combustion device since a combustion halts.

Abstract: In a cooking device having a housing which can be closed by a door, a hinge support in the form of a slide or carriage is guided at one side wall so as to be displaceable at guide rails which are arranged horizontally at the side wall. One part of a hinge arrangement is fastened at the hinge support and the other part of the hinge arrangement is fastened to the door. The hinge support is guided at the guide rail by guide rollers which contact the guide rails in a positive engagement without play. In this way it is possible when opening the door to displace the same into a parallel position alongside the side wall.

Abstract: An improved push button switching unit is proposed of which the indicia on the key top is recognizable even in a dark place. Namely, a phosphorescent layer emitting phosphorescence even in a dark place is formed on the upper surface of the key top to provide recognizability of the indicia and further the switching unit is provided with a light sensor means and a light source which is lighted when the ambient lightness is low as detected by the sensor means. When the switching unit is used continuously in a dark place, the light source repeats cycles of a lighting period, in which the phosphorescent layer accumulates the energy of light, and a dark period, in which the phosphorescent layer emits phosphorescence by means of the accumulated energy, so that the power consumption for lighting the light source can be saved.

Abstract: A fuel injector has an inner pipe within an outer pipe. The distal end of the inner pipe is set back from the distal end of the outer pipe to create a flame stabilization and mixing zone. A combustible gas and air mixture injected through the outer pipe forms a flame shroud around a gas stream injected through the inner pipe. This injector provides increased flame penetration and improved NO.sub.x reduction particularly when used to inject a flame shrouded gas stream into regions of the furnace at which the flue gas is at a temperature not greater than 2400.degree. F.
