Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing condensate management systems for steam consumers face challenges in reliably detecting steam leaks, which lead to energy loss, increased maintenance costs, and inefficient process control due to complex calibration requirements and susceptibility to pollution-induced valve partial closure.
Innovation Solution
A procedure for operating a condensate system that involves monitoring the level of condensate in a reservoir, performing an emptying process between defined maximum and minimum levels, and using a measurement system to determine the volume and mass of condensate, thereby accurately measuring the amount of steam lost and optimizing energy usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If electronic level sensors are used to monitor condensate level in the drain, then the condensate level can be detected, but the system becomes complex and susceptible to pollution-induced valve partial closure
Solution Approach 1:
The invention extracts the measurement function from the condensate reservoir environment by placing the measuring sensor in the supply line upstream of the reservoir. This removes the sensor from the polluted condensate environment, preventing contamination while maintaining level detection capability. The sensor only needs to detect the condensate level in the supply line, which is sufficient to control the emptying process.
Solution Approach 2:
The invention uses the supply line as an intermediary medium to indirectly measure the condensate level in the reservoir. By measuring the level in the supply line (which is connected to the reservoir), the system obtains the necessary information without directly exposing sensors to the harsh reservoir environment, thus simplifying the overall system design.
2Measurement precision
If complex calibration requirements are imposed on the measurement system, then measurement precision can be improved, but the ease of operation and maintenance decreases
Solution Approach 1:
The invention enables the measurement system to automatically determine steam loss based on the condensate volume measured in the supply line. The control unit calculates the steam loss directly from the measured condensate amount without requiring manual calibration or complex adjustments. The system self-calibrates by using the physical relationship between condensate accumulation and steam loss, eliminating the need for external calibration procedures.
3Reliability
If the condensate reservoir is continuously emptied, then the condensate level can be controlled, but energy loss increases due to frequent valve operations
Solution Approach 1:
The invention implements periodic emptying of the condensate reservoir based on the condensate level detected in the supply line. Instead of continuous emptying, the system opens the drain valve only when the condensate level reaches a predetermined threshold in the supply line, then closes it after emptying. This periodic operation reduces the frequency of valve operations, minimizing energy loss while maintaining reliable condensate level control.

AI summary
The invention relates to a method for operating a condensate drain (1), wherein the fill level of a condensate (2) that is accumulated and/or accumulating in a condensate reservoir (3) of the condensate drain (1) is monitored, and the condensate (2) is fed to an outlet (7) of the condensate drain (1) when a maximum fill level (5) of the condensate (2) in the condensate reservoir (3), determined by a sensor (4), is reached. During each emptying process, the same quantity of condensate (2) between the maximum fill level (5) and a minimum fill level (6) of the condensate (2) in the condensate reservoir (3) is always discharged. The invention further relates to a condensate drain (1) for carrying out the method.
