AI Technical Summary

Technical Problem

Existing control systems for combustion appliances, such as gas boilers, face challenges in preventing the use of incorrect setting parameters for gas valves, particularly when valves for natural gas and hydrogen share the same connectors, leading to potential unsafe operations and explosion risks due to mix-ups.

Method used

A method and control system that receive and compare actual information data from gas valves with predefined data to modify the operation of the appliance, ensuring correct parameter settings by blocking, updating, or closing the valve if mismatched, thereby preventing unsafe conditions.

Benefits of technology

This solution effectively reduces the risk of unsafe operations and explosions by ensuring correct gas valve settings, even when valves for different types of fuel gases share the same connectors, providing continuous safety checks and preventing incorrect ignition attempts.

Abstract

Method (100) for controlling the operation of a combustion appliance (1), in particular a gas boiler, the combustion appliance (1) being operated based on setting parameters, which are set up based on at least predefined information data on a gas valve (2), the method (100) comprising receiving (S101) a valve signal (13) from a gas valve (2) of the combustion appliance (1), the valve signal (13) comprising actual information data with respect to the gas valve (2), comparing (S102) the actual information data with the predefined information data with respect to the gas valve (2), and modifying (S103) the operation of the combustion appliance (1) when the actual information data are different from the predefined information data.
