Abstract:
Die vorliegende Erfindung betrifft eine Vorrichtung bzw. ein Verfahren zur Überwachung von Brennern mit einem Feuerungsautomaten (1) zur Steuerung bzw. Regelung des Brenners (15) und einem Temperaturwächter (5), wobei mindestens die Vorlauf-/Kesseltemperatur (T?VL?) detektiert und mittels des Temperaturwächters (5) mit einer vorbestimmbaren ersten maximalen Vorlaufkesseltemperatur (T?VLmax1?) verglichen wird und wobei der Brenner (15) abgeschaltet wird, wenn die Vorlauf-/Kesseltemperatur (T?VL?) die vorbestimmbare erste maximale Vorlauf-/Kesseltemperatur (T?VLmax1?) erreicht oder überschreitet, während die Vorlauf-/Kesseltemperatur (T?VL?) mit einer vorbestimmbaren zweiten maximalen Vorlauf-/Kesseltemperatur (T?VLmax2?), die höher ist als die vorbestimmbare erste maximale Vorlauf-/Kesseltemperatur (T?VLmax1?) verglichen wird und wobei der Brenner (15) abgeschaltet und verriegelt wird, wenn die Vorlauf-/Kesseltemperatur (T?VL?) die vorbestimmbare zweite maximale Vorlauf-/Kesseltemperatur (T?VLmax2?) erreicht oder überschreitet und zusätzlich ein Fehlersignal (F) des Temperaturwächters (5) erzeugt wurde, wobei das Fehlersignal (F) dann erzeugt wird, wenn der Brenner (15) durch den Temperaturwächter (5) bei Erreichen der ersten maximalen Vorlauf-/Kesseltemperatur (T?VLmax1?) nicht ordnungsgemäß abgeschaltet wurde.
Abstract:
An appliance controller suitable for controlling a heating appliance (e.g., gas-fired water heating apparatus) having a distributed control system. The distributed control system includes a host computer and one or more heating control units. In accordance with a preferred embodiment, each heating control unit takes the form of an ignition control for controlling operation of a gas-fired burner for a multi-stage boiler. The appliance controller also includes a fault isolation system for isolating the source of a malfunction, and providing service personnel with status information regarding components of the appliance. The appliance controller is adapted to provide variable output signals for adaptive control of some appliance components, such as a blower or a circulation pump.
Abstract:
An instantaneous gas hot water heater, the heater (1) being controlled by a controller (8) which senses the outlet water temperature (5), the water inlet temperature (4) and the water flow rate (6). The controller (8) is pre-set with the desired water temperature, and the controller (8) thus calculates the heat required and adjusts the gas flow rate accordingly via a gas modulating valve (14).
Abstract:
A method is provided for tuning an oxygen trim controller during the commissioning of a combustion control system for controlling operation of a boiler combustion system, rather than tuning the oxygen trim controller after the commissioning process has been completed.
Abstract:
Water (9) in a fuel cell accumulator (10) is kept above freezing by a hydrogen/oxygen catalytic combustor (13) fed hydrogen through a mechanical thermostatic valve (25) in thermal communication (26) with the container (10) or the air nearby, and connected to hydrogen (28), optionally in series with a timer valve (183). The combustor may comprise an ejector (32) having hydrogen through its primary inlet (31) drawing air through a secondary inlet (33), or a diffusion combustor having a catalyst (38), including TEFLON® to permit water generated by combustion to flow by gravity out of the catalyst, spaced from a heating surface (30), and a diffusion control device (40); low partial pressure of oxygen at the catalyst causing diffusion through the device. Combustion vapor condenses on a surface (146) and is led by hydrophilic woven carbon paper (126) and wicking material (133) downwardly, through a disk (140) and plugs (147) either to ambient, to a salt canister (190), or to a porous hydrophilic mixer (200) for mixture with antifreeze (206).

Abstract:
A system, device and method for indicating the performance of a combustion boiler(l) used for heating water, the boiler comprising a burner(2), an air intake for the burner, a flue (3) for exhaust gas from the burner, and a water heating circuit having a flow heating water outlet(4) and heating water inlet (5), the water flowing within the boiler from the water inlet to water outlet past the burner. The system comprises a temperature sensor for obtaining a measurement of combustion air intake temperature (Ta) in the air intake for the burner; a temperature sensor for obtaining a measurement of flue gas temperature (Tg) in the flue for exhaust gas from the burner,- a temperature sensor for obtaining a measurement of heating flow water temperature (Tf ); and a temperature sensor for obtaining a measurement of heating inlet water temperature (Tr). A processor receives inputs from the temperature sensors and provides an output based on the obtained temperature measurements. An indicator (6) receives the output from the processor and provides an indication to a user relating to the performance of the combustion boiler.
Abstract:
Described is a vehicle heater with several heat-output settings. When heaters of this kind are switched from one setting to another, annoying noises are produced by the actual switching operation and by the rapid change in rpm of the combustion-air fan (10) of the burner (2) in the heater. In order to avoid this, the invention calls for a smooth, gradual change in fan rpm whenever the heater is switched from one output setting to another.
