Gas Boiler Flow Plausibility Check via Pulse Modulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for checking the plausibility of gas mixture volume flow in burners are inefficient due to the need for multiple measurements to account for rapidly changing environmental conditions and require significant computational effort, leading to falsified comparison values and high memory requirements.
Innovation Solution
A method involving pulse-like modulation of the fuel gas volume flow, where measured values are processed in real-time to calculate sums and determine the running time of the modulation, allowing for plausibility checks without storing the entire response signal, reducing data storage and processing needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple consecutive measurement series with averaging are used to account for rapidly changing environmental conditions, then measurement precision is improved, but device complexity and computational effort increase
Solution Approach 1:
The invention extracts only the necessary measurement data (measured value V at specific time points) from the complete response signal, processing only the essential information needed for plausibility verification rather than the entire signal history, thereby reducing computational complexity while maintaining measurement accuracy
Solution Approach 2:
The measurement process is segmented into discrete time points (t1, t2, t3) with specific measurement actions at each point, allowing the system to process measurements in isolated steps rather than continuously, reducing the computational burden while maintaining comprehensive verification
2Measurement precision
If the entire response signal V(t) is stored for later evaluation, then measurement precision is improved, but memory requirements and data processing load increase
Solution Approach 1:
The invention extracts only the essential measured values at specific time points (V at t1, t2, t3) from the complete response signal, storing only these critical data points rather than the entire continuous signal, thereby significantly reducing memory requirements while maintaining verification accuracy
Solution Approach 2:
The system performs partial measurement and processing by evaluating only the necessary measured values at specific moments rather than processing the complete signal history, achieving sufficient verification accuracy with minimal data storage
3Device complexity
If rapidly changing environmental conditions are not accounted for, then device complexity is reduced, but measurement precision deteriorates due to distorted comparison values
Solution Approach 1:
The invention performs preliminary measurements at specific time points (t1 before modulation, t2 during modulation, t3 after modulation) to capture the system state under different conditions, allowing the evaluation to account for environmental variations without requiring complex continuous adjustment mechanisms
Solution Approach 2:
The system uses the measured values from different time points as feedback to verify plausibility, comparing the measured response against expected behavior to detect and correct for distortions caused by rapidly changing environmental conditions

AI summary
Method for verifying the plausibility of a gas mixture volume flow in a burner in which a gas mixture (5), comprising a gas (4) and a fuel gas (3), is burned in a combustion chamber (11) by a combustion process, wherein the combustion process is monitored by evaluating a measured value V of at least one sensor, wherein the measured value V is related to the combustion process in such a way that the quality of the combustion of the fuel gas can be detected.
