The largest gas engine yet developed by GE Jenbacher, the 9.5 MW J920 FleXtra, has taken its place in the upgraded municipal cogeneration facility that feeds the district heating system in the city of Rosenheim, Germany.

The new engine generator sits beside four existing Jenbacher engines – three 3.35 MW J620 engines and a 4.4 MW two-stage turbocharged J624 unit – plus an existing waste incineration plant.

Stadtwerke Rosenheim's integrated cogen facility now has an electricity generating capacity of 36 MW and a heat generation capacity of 44 MW. It meets about 40% of the electricity needs and 20% of the heating requirements of the city – which has more than 61,000 inhabitants, and lies 450 metres above sea level in the upper-Bavarian Alpine foothills.

This impressive installation will help meet Germany's goal to increase power from CHP from today's 15% to 25% of the country's power supply by 2020, as part of its larger energy transition (Energiewende) strategy. Germany is already the largest single market for CHP in Europe, accounting for more than 20% of the electricity from cogeneration across the EU-27, but it will need many more new CHP plants to meet the 25% target that was set last year in a new CHP law.

Speaking at the start-up of the expansion of the Stadtwerke Rosenheim plant, the Bavarian minister of state for Environment and Health, Dr. Marcel Huber, stressed the role of local government bodies: 'The energy transition plan, Energiewende, can be achieved only if there is a cooperative effort, including contributions by municipal providers'.

'Investments in innovative, modern power plants create an important foundation for the successful execution of our energy transition plan,' he added

As part of Energiewende, Germany plans to close all nuclear power plants by 2022. To replace the massive amount of low-carbon baseload electricity from the nuclear power plants, the transition plan calls for increasing use of natural gas and renewable energy, and greater use of energy efficiency technologies. GE is also keen for Rosenheim to act as a demonstration of the role of distributed energy, to promote energy security across Europe.

Technology, both flexible, and efficient

The Rosenheim project's centrepiece is GE's largest and newest Jenbacher gas engine, the 9.5 MW J920 FleXtra, which GE calls a flexible power solution. It combines innovation with power and efficiency to help customers address their local energy security priorities, while achieving improved environmental performance.

GE expects to make the engine available in 60 Hz regions of the world in 2014.

The CHP system provides electricity and thermal power (hot water) for local residents and industrial customers. It has a lower-carbon footprint than conventional power plants and boilers, and will assist Germany's effort to reduce greenhouse gas emissions by 40% by 2020. The engine's fast start-up aids Stadtwerke Rosenheim's operational flexibility, to overcome the challenges of intermittency caused by adding wind and solar energy supplies to the electricity grid.

The J920 FleXtra has the highest electrical efficiency in the 10 MW class of gas engines, of 48.7%, and about 90% efficiency in cogeneration mode, depending on heat utilization, says GE. Its two-stage turbocharging design will also help Stadtwerke Rosenheim to meet Germany's goal to improve its energy productivity – related to prime energy usage – by 2.1% annually.

'Our flexible J920 technology offers both high efficiency and reliability levels, which makes it the ideal large gas engine distributed power solution for industrial and grid stabilisation applications, while also minimising the customer's carbon footprint,' said Karl Wetzlmayer, general manager of Gas Engines for Power Generation, GE Power & Water.

11:45pm on Wednesday 26th February 2014, a fire was detected at GEA Searle in our Research & Development department. The Fire Brigade arrived within 10 minutes of the alarm being sounded, however the fire had taken hold by then and spread into the Final Assembly area. It took most of the night to put the fire out – mainly due to combustible roof materials. There were no injuries to any employees or any fire brigade personnel.

The commercial director Richard Saunders said "Once the building was cleared, the damage wasn’t as extensive as expected.

18 per cent of the site buildings were actually burned. (Expected duration for re-build will be 12 to 15 months).

Sales and Marketing Director Mark Knapman said “We’re really not in a bad place”. He added “All the staff have been in today, we’ve had people in overnight clearing up and we’ll have people in over the weekend.”

The fire affected one end of the complex, the oldest part of the building which also contained the paint shop and coil coating area but the stores were unaffected. The firewall between the main assembly area and the stores did its job.

GEA Searle paid tribute to the efforts of the fire service and the support, encouragement and offers of help from customers and suppliers.

Luckily nobody was injured at the dry cooler site.

If you are looking for a company to supply industrial cooling equipment, including dry coolers, then take a look at Industrial Power Cooling (IPC) UK. They are a sales, marketing, design and project engineering management company with links to some of Europe’s top manufacturers of industrial cooling products. They supply to many industries, including power generation, energy, oil and gas, and petrochemical industries.

Dry coolers are often used to cool condensed water in refrigeration and air conditioning systems, and are also used in processing for closed circuit cooling of processing liquids. They are generally quiet to operate, so are suitable for noise-sensitive environments. IPC’s dry coolers are all manufactured by Alfa Laval, who have been creating and supplying heat transfer, separation and fluid handling technologies for over 100 years. Headquartered in Sweden, Alfa Laval operates around the world, and IPC supply over 10 types of Alfa Laval dry coolers, ranging from solar SD radiators through to industrial DCH radiator units suitable for use in shipping containers and for diesel and gas power generation systems.
