Abstract:
An ignitor spark indicator 100 is described that monitors RF signals within a flame rod 25 located near a spark rod 23. The signal from the flame rod 25 is processed to provide a waveform that indicates when electrical arcing is occurring. The indication when arcing is occurring is also provided to flame-detecting equipment. The flame-proving device 60 only operates when the arcing is not produced so that the flame-detecting device 60 does not confuse the arcing with a flame reducing the false positive determinations.
Abstract:
The invention relates to a stove (40) with a burner (41) and a device for the exchange of the combustion air and the flue gas. This said device has a simple design in various types (1, 3, 5, 7, 9, 53, 57, 60, 63) and its said function is to protect the flame against extinguishing in unintended cases. Each of these various types of designs (1, 3, 5, 7, 9, 53, 57, 60, 63) can be arranged collectively in a matrix-like shape, for example 2 x 2 (2, 4, 6, 8, 10, 55, 59).
Abstract:
Die Erfindung betrifft eine Brenneranordnung mit einer eine Vielzahl von Durchbrüchen (2) aufweisenden Brennerplatte (1) und einer Überwachungseinrichtung zur Überwachung der Ausbildung einer sich von der Brennerplatte (1) erstreckenden Brennzone (3), wobei die Überwachungseinrichtung eine an einer flammenseitigen Oberseite (4) der Brennerplatte (1) vorgesehene Kathode (5) und eine im Bereich der Brennzone (3) angeordnete Anode (7) umfasst. Zur Verbesserung der Temperaturbeständigkeit und damit der Haltbarkeit ist erfindungsgemäß vorgesehen, dass die Brennerplatte (1) aus einem nicht-metallischen Werkstoff hergestellt und die Kathode (5) als separat ausgebildetes Bauteil im Bereich der Oberseite (4) der Brennerplatte (1) angeordnet ist.
Abstract:
The present invention is directed at systems and methods for detecting flue (24) blockages in an HVAC system (10) without the addition of numerous additional sensor elements, wiring, and connections that can unduly increase the cost and possibly reduce the reliability of the HVAC system, In an illustrative embodiment of the present invention, changes in the output of a flame sensor (26) are used to detect when a likely flue blockage exists.
Abstract:
A device (1) for the control of a burner (2) in general comprises an electrical control unit (7) for the lighting and automatic control of flame in the burner and a valve unit including: normally-closed valve means (5, 6) which are disposed in main line (3) for the supply of fuel to the burner (2) and can be opened by the control unit (7), means (14), controlled by the control unit (7), for automatically lighting the flame in the burner, and flame-detection means (17) associated with the burner and connected to the control unit (7). The device (1) also comprises actuator means (18) operatively associated with the control unit (7) and connected to the valve means (5, 6) for the manual operation thereof when the control unit (7) is deactivated owing to lack of electrical energy. When the control unit (7) is activated upon the return of the electrical energy, the actuator means (18) are relieved of the control of the valve means (5, 6).
Abstract:
The invention concerns means for the installation in an air-gas feeding duct, a standard thermocouple to provide both a cold safety function in case of extinction, and a hot safety function, without any additional device, in case of internal combustion. The downstream portion of the bulb side (4) of the thermocouple penetrates into the air-gas duct (2). Its probe tip (3) is immobilised against the inner surface of the diffusion chamber (5) at the centre of the combustion chamber (6). Its connector (16) is secured to its exit point from said duct (2) at a marker-projection (17) by a lock (15). The life span of the thermocouple is considerably increased through permanent cooling by the fresh air-gas mixture of the elements proximate to combustion. In case of internal combustion, the inversion of temperature gradients of the cold and hot junctions of the thermocouple causes the generated electromotive force to fall rapidly. The device is designed for high temperature confinement burners.
Abstract:
According to the inventive method, the ionization signal for operation with a nominal load and operation with a partial load is determined at a first point in time. A first difference between the ionization signal for operation with a nominal load and the ionization signal for operation with a partial load is determined for this point in time. The ionization signal for operation with a nominal load and operation with a partial load is then determined at a second point in time and the second difference between the ionization signal for operation with a nominal load and the ionization signal for operations with a partial load is then formed for this second point in time. The first difference and the second difference are compared with each other and the state of the gas burner is established depending on the result of this comparison.
Abstract:
A water heater that includes a water container, a combustion chamber, adjacent the water container, having at least one inlet to admit air and extraneous fumes into the combustion chamber, at least one inlet comprising a metal plate through which pass a plurality of ports, the ports comprising a plurality of slots and holes, each slot having a quenching distance and each hole having a quenching distance and being capable of confining ignition and combustion of said extraneous fumes within the combustion chamber; and a burner associated with the combustion chamber and arranged to combust fuel to heat water in the container.
Abstract:
A gas water heater including a water container adapted to be heated by a gas burner; and an enclosure surrounding the burner, the enclosure having at least one heat sensitive entryway adapted to allow air and fumes to enter the enclosure without igniting flammable gases or vapors outside of the enclosure.
Abstract:
The burner (1) is operated with a burnable gas and a gas that contains oxygen. Said burner contains at least one helical gas path for the burnable gas or gas that contains oxygen. Three twisted pipes (2) are used advantageously as a gas path for the burnable gas. A control pipe (4) is also arranged advantageously inside the burner on the center axis in order to monitor the flame by infrared. As a general rule, natural gas is used as a burnable gas and pure oxygen is used as a gas that contains oxygen.
