Method for operating a thermotechnical system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Thermotechnical systems face inefficiencies and operational risks due to contamination, which existing monitoring methods fail to predict and address proactively, leading to potential failures and increased costs.
Innovation Solution
A method for anticipatory monitoring of contamination in thermotechnical systems involves detecting contamination values, extrapolating future contamination trends, determining an expected time to reach critical levels, and writing this data into memory for system control, enabling timely maintenance and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contamination monitoring is performed using existing methods, then contamination detection is possible, but predictive capability and proactive maintenance planning are lacking
Solution Approach 1:
The patent applies preliminary action by calculating and storing an expected time of reach value that predicts when contamination will reach critical levels before actually happening. This allows maintenance to be scheduled in advance based on predicted contamination trends rather than waiting for actual critical contamination to occur, thereby improving system reliability and eliminating reactive delays.
2Loss of information
If continuous monitoring of contamination values is implemented, then contamination status is tracked, but timely prediction of critical levels and maintenance scheduling is not achieved
Solution Approach 1:
The patent implements feedback by continuously monitoring contamination values, comparing them against critical thresholds, and using this information to calculate and update the expected time of reach value. This closed-loop feedback system ensures that maintenance scheduling is based on real-time contamination status while providing predictive information about when critical levels will be reached, improving both information availability and maintenance efficiency.
Solution Approach 2:
By calculating the expected time of reach value in advance based on current contamination trends, the system enables maintenance to be planned and executed before critical contamination occurs. This preliminary action transforms continuous monitoring data into actionable predictive information, eliminating information gaps about critical timing and optimizing maintenance productivity.
3Productivity
If maintenance is performed based on actual contamination levels, then system efficiency is maintained, but preventive maintenance and failure avoidance are not optimized
Solution Approach 1:
The patent applies preliminary action by predicting the expected time of reach value for critical contamination levels before they are actually reached. This allows maintenance to be scheduled proactively based on predicted contamination trends rather than waiting for actual critical contamination to occur, thereby maintaining system efficiency while optimizing failure prevention capability through timely preventive maintenance.

AI summary
The inventive method for operating a thermal engineering system, wherein the thermal engineering system comprises several components, in particular a boiler, is characterized in that an expected arrival time value is determined from recorded pollution values of the thermal engineering system and/or at least one component, at which a predefinable critical pollution value of the thermal engineering system and/or the at least one component is reached or exceeded, in particular for the first time, and that the expected arrival time value is written to a memory.
