16 MUNICIPAL UTILITY, LÜNEN In co-operation with the Ardagh glassworks, "Stadtwerke Lünen" (municipal utility) use waste gas heat from the glass production for several purposes. The initial gas temperature of 460 C is cooled down to 230 C in a waste heat recovery steam generator (WRSG). On a high-pressure pipe the steam from the WRSG is then used by a steam motor to produce electrical energy. From that highpressure pipe, a medium- and a low-pressure pipe supply the production plant with steam. The Energy Module is integrated in the medium-pressure system in parallel to other facilities relevant for the production cycle. Only steam which is not required for other purposes is fed into the Energy Module with a pressure of about 3 bar at 133 C. Technical Data: Application: Back pressure system in series with condenser Outlet pressure: 1.3 bar (abs) at 107 C Steam mass flow: ~500 kg/h saturated steam Electrical output: ~11 kw Electricity produced: ~88,000 kwh/a CO2 saving: ~ 60 t/a Set to work: December 2009 Input pressure: ~3.0 bar (abs) at 133 C 16

On a high-pressure pipe the steam from the WRSG is then used by a steam motor to produce electrical energy.

17 SAND-LIME BRICK FACTORY At the sand-lime brick factory in Höltinghausen, autoclaves are used for hydrothermal hardening of calcareous sandstone. The autoclaves are filled with steam and kept under a steam pressure of up to 16 bar for up to 8 hours, depending on the composition of the mixture. When the hardening process is completed the steam is supplied to other autoclaves. The remainder of the steam, which still has exergic energy, is reduced by means of the Energy Module from a pressure of 4 bar to a lower pressure; at the same time electrical energy is produced. The expanded steam is used in a preheater for production of processed condensate and fresh water. Technical Data: Application: Expansion of steam for preheater Input pressure: ~3.0 bar (abs) at 134 C Electrical output: ~18 kw Electricity produced: ~63,000 kwh/a CO2 saving: ~ 40 t/a Set to work: April 2010 Outlet pressure: 1.3 bar (abs) at 107 C Steam mass flow: ~1,400 kg/h saturated steam 17

When the hardening process is completed the steam is supplied to other autoclaves.

18 BRICKWORKS (SWITZERLAND) In a kiln the bricks are baked and hardened. Thermo-oil is used for heat recovery. It is heated with the hot gas from the kiln and is then transported through pipes to sites where heat is required for production purposes. Among others, waste heat is used for production of steam which is the fed into the Energy Module to produce electrical energy. The expanded steam with a temperature of approximately 105 C is used in a heat condenser for heating purposes. Technical Data: Application: Heat recovery and steam production Input pressure: 4.0 bar (abs) at 144 C Outlet pressure: 1.2 bar (abs) at 105 C Electrical output: ~9 kw Electricity produced: ~72,000 kwh/a CO2 saving: ~46 t/a Set to work: June 2011 Steam mass flow: ~600 kg/h saturated steam 18

Among others, waste heat is used for production of steam which is the fed into the Energy Module to produce electrical energy.

19 BIOMASS POWER PLANT The biomass power plant is operated with biogenous solid fuels such as residuals from woodworking or forest wood unsuitable as timber or lumber. Steam overheated in the waste heat boiler is supplied to a condensing turbine for production of electricity. The Energy Module is assembled between turbine and vaccum condenser so that the increased pressure difference of the remaining steam can be used for production of additional electrical energy. The condensate is processed and pumped back into the boiler. Technical Data: Application: Back pressure plant in series with a condenser Steam mass flow: ~5,000 kg/h saturated steam Electrical output: ~75 kw Electricity produced: ~637,000 kwh/a CO2 saving: ~407 t/a Set to work: October 2011 Input pressure: 1.5 bar (abs) at 111 C Outlet pressure: 0.5 bar (abs) at 81 C 19

The Energy Module is assembled between turbine and vaccum condenser so that the increased pressure difference of the remaining steam can be used for production of additional electrical energy.

20 COKERY At the cokery, process steam is filtered by means of steam washers. For protection of the washers the pressure of the process steam must be reduced from 3.3 bar to 1.3 bar. The Energy Module is switched in parallel to an existing pressure reducing station. It expands the steam, reduces the pressure and produces electrical energy. Technical Data: Application: Pressure reducing station Input pressure: 3.3 bar (abs) at 137 C Electrical output: ~65 kw Electricity produced: ~382,000 kwh/a CO2 saving: ~244 t/a Set to work: Sept Outlet pressure: 1.3 bar (abs) bei 107 C Steam mass flow: ~3,000 kg/h saturated steam 20

to 1.3 bar. The Energy Module is switched in parallel to an existing pressure reducing station.
