Compressor technology is something we master at Energetic. One of our customers approached us to perform an inspection on a compressor. This old compressor had suffered a lot of damage over the past few years and had undergone multiple repairs and a major overhaul 3 years ago.
Energetic machinery was called in for an overhaul on a Steam Turbine MAN MARC2-C10, 10 MW. During this inspection, several problems were found in the turbine. Steam leakages where observed at the split line of the casing at the level of the stuffing box DE side.
After a power failure in the power supply of the control/protection system, a situation occurred in which the generator operated as a motor after the steam supply to the turbine was cut off (turbine trip). The turbine operated at reverse power for about 4 hours causing damage in the turbine. Energetic was called in to investigate this situation and to submit a repair proposal.

Problem: Regularly tripped due to high vibration value’s caused limitation of production capacity because of the lower amount of dewatering per min.
Near a city of millions in southern Europe, a water treatment plant is equipped with a series of PGW Schiele turbo aeration blowers. One of these blowers was out of operation, which meant that the reserve capacity was lost. The blower was seriously damaged at the level of the impeller, further investigation revealed that the bearings and the pinion were badly damaged.
After 10 years of continuous production, an ABB turbine, in a cogeneration configuration, was entrusted to Energetic to carry out a major overhaul. During the preparation a no stop inspection was carried out. As a result, it was decided to execute on the generator only di-electrically measurement and to pay special attention to the efficiency loss the turbine had to deal with.
In order to guarantee delivery of nitrogen and oxygen to their main customer, a North Italian air separation plant required a back-up compressor. Investing in a new system however would mean financial haemorrhage. Luckily, they still owned a totally obsolete GHH Borsig main air compressor and KRUPP DSU 32X Planetarium gearbox. Energetic gave this installation a new lease of life, at a fraction of the cost of a new system.

During overhauls, the steam control valves and emergency steam valve or stop valve are also inspected. Not only because of possible leaks of steam or oil side, but also to ensure the proper functioning of the valves.
A ljungström radial turbine maintenance is for many turbine service companies no ordinary self-evident activity. In order to be able to carry out an inspection and repair activity, one needs to have the knowledge and a lot of experience with this typical stal Laval turbine application. A German customer working in the steel industry can talk about this.
Energetic nv is the most advanced third party to maintain your 'stal' turbines. Our engineers, supervisors & technicians have an exceptional reputation in the field of technical knowledge regarding the radial type of ljungström turbines (stable laval ABB sauter Harlé).
The people of Energetic have a very extensive and long experience with this type of turbines. Not only are customers being helped to solve problems by means of trouble shooting, but planned maintenance and inspections are also being carried out.

Interest in how we solved this?
Last year’s European More4Core project showed 44% of the assets present in the North-West European industry will reach the end of their lifecycle within the next decade. Replacing all this machinery is financially unfeasible, while at the same time manufacturing plants would rather continue to use current installations. Prolonging the lifecycle therefore seems to be the magic word. But how to go about this?
