A system for checking high fluid pressure and low fluid pressure limit switches for valves and fluid supply to a fluid consumption appliance. The system may incorporate one or more pressure sensors at a fluid valve to detect an amount of fluid pressure. The one or more pressure sensors may be connected to a processor. The high fluid pressure and low fluid pressure sensor limit switches may also be connecter to the processor. A display and user control may be connected to the processor.

For the automated adjustment of a heating system (2), there is produced between an exhaust-gas measuring device (1) and a control unit (26) a data connection (6) via which data, measurement values or control or setting signals for the adjustment of the heating system (2) are transmitted at least from the exhaust-gas measuring device (1) to the control unit (26). During the adjustment of the heating system (2), at least one exhaust-gas parameter is measured in automated fashion by way of at least one exhaust-gas sensor (4) of the exhaust-gas measuring device (1), and determined measurement values are automatically detected by the exhaust-gas measuring device (1). Then, a deviation of the determined measurement value from an exhaust-gas-parameter-specific and/or installation-specific setpoint value is determined, and in a manner dependent on the determined deviation, an automated adjustment of the heating system (2) is performed, said adjustment being initiated by the control unit (26) (cf. FIG. 1).

A gas destruction system using a gas destroying device communicatively coupled to an electronic controller subsystem for neutralizing unwanted gas emissions. The system includes a gas destruction device and method and can be customized to variable conditions by way of controlling available flow area. The disclosed gas destruction device includes multiple combustion manifolds separated by valves, which allow gas to flow to sets of nozzles as needed to maintain stable combustion. The system consists of multiple nozzles for gas flow, a main shutoff valve, a flow measurement sensor, and an igniter and power source. The combustion products are allowed to flow through the exhaust outlet attached to the combustor. A communicator device is included in the system to send system information, preferably wirelessly. The system can operate autonomously via local or remote controllers, or manually via local or remote commands.

Various embodiments include a combustion apparatus comprising: a control facility for open- and/or closed-loop control of the apparatus; a combustion chamber; an actuator adjusting an air supply; and a combustion sensor in a region of a flame of the chamber. The control facility stores a list of support points. A first air supply value is assigned to each support point. A drift test value and an index for ascertainment of a test result are assigned to each support point. The controller: generates a specified air supply; selects a support point as a function of the air supply; and decides on a test result using the index for the support point. To ascertain a test result: receives a signal from the combustion sensor; determines a new test result; ascertains a changed drift test value for the selected support point; and stores the changed drift test value as the drift test value.

A gas burner comprises an automatic firing unit for regulating or controlling an amount of gas supplied to the gas burner via a gas control valve and a lambda probe (1) arranged in the exhaust gas flow for measuring a residual oxygen content in the exhaust gas. A method for operating the gas burner comprises a first operating state in which the gas burner is operated in standard mode, wherein the residual oxygen content in the exhaust gas is regulated via the measured value of the lambda probe (1). According to the invention, in a second operating state, the gas burner performs a fault test on the lambda probe (1) involving the steps of: deactivating (S18) a supply of power to a pump cell (PZ) of the lambda probe (1); determining a present test voltage (h) of a measurement cell (NZ) of the lambda probe (1); comparing (S25) the present test voltage (h) with a predefined test setpoint voltage (i) and determining a difference; and if the difference exceeds a predefined limit value, performing a safety deactivation (S29); or if the difference does not exceed the predefined limit value, operating the gas burner in the first operating state.
