TAPROGGE is the worldwide renowned specialist for condenser inspections. In power stations and industry the condenser inspection (the inspection of the evaporators in seawater desalination plants, resp.) is an indispensable means for the determination of possible failures and for the recognition of the optimization potential of the respective heat exchanger.
Inspections of Heat Exchangers
- Inspection of heat exchangers
- Endoscopic tube examination
It furnishes information about:
- macro fouling on the tubesheet
- degree of fouling of the cooling tubes
- fouling and corrosion aspects
- ball distribution across the tubesheet
- dead spots
As far as necessary TAPROGGE uses for its inspections the technical possibilities of endoscopy and other measuring techniques for surface conditions. Tube samples are helpful for the subsequent diagnosis in the TAPROGGE technological centre.
Ball Distribution Tests
- Ball Distribution Analysis
Ball distribution tests are always helpful when there are questions with regard to ball distribution, for instance due to hydraulic conditions. By means of special catching baskets that are temporarily fixed to the heat exchanger outlet tubesheet the actual distribution of balls can be determined and a clear statistic picture established. Optimizations - if necessary - can then be performed by the selection of adequate cleaning balls.
Flow Measurement
- Flow Measurement
The exact measurement of water flows is a particular challenge among the installation conditions of operational practice. Measuring with high accuracy in terms of flow is required
- for the hydraulic layout of installations of cooling water technology
- for the determination of thermodynamic economical appraisals
- as a diagnostic instrument in cases of failure
Regular instruments are generally not appropriate for this task; highly accurate, complex techniques often too costly. To fulfill this goal TAPROGGE has focussed on ultrasonic measurement because for the multitude of cases this method has the necessary operational flexibility at acceptable cost and sufficient accuracy.
Tests for optimized Heat Exchanger Operation
Tasks of process technology are sometimes quite complex, above all when choosing the appropriate tube material, but also in the interaction of water quality, water chemistry, cooling tube material and cleaning balls. They often call for the situation related test for mastering or optimizing a special problem.
In this field as well TAPROGGE is technically leading. Numerous operators were provided by us with tester plants designed for their special applications, and with process-technological advice.
