MUNICIPAL UTILITY, LÜNEN
Technical Data:
Application: Back pressure system in series with
condenser
Input pressure: ~3.0 bar (abs) at 133 °C
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
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 high-pressure pipe, a medium- and a low-high-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.
SAND-LIME BRICK FACTORY
Technical Data:
Application: Expansion of steam for preheater
Input pressure: ~3.0 bar (abs) at 134 °C
Outlet pressure: 1.3 bar (abs) at 107 °C
Steam mass flow: ~1,400 kg/h saturated steam
Electrical output: ~18 kW
Electricity produced: ~63,000 kWh/a
CO2 saving: ~ 40 t/a
Set to work: April 2010
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.
BRICKWORKS (SWITZERLAND)
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
Steam mass flow: ~600 kg/h saturated steam
Electrical output: ~9 kW
Electricity produced: ~72,000 kWh/a
CO2 saving: ~46 t/a
Set to work: June 2011
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.
BIOMASS POWER PLANT
Technical Data:
Application: Back pressure plant in series with a
condenser
Input pressure: 1.5 bar (abs) at 111 °C
Outlet pressure: 0.5 bar (abs) at 81 °C
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
The biomass power plant is operated with biogenous solid fuels such as residuals from
wood-working 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.
COKERY
Technical Data:
Application: Pressure reducing station
Input pressure: 3.3 bar (abs) at 137 °C
Outlet pressure: 1.3 bar (abs) bei 107 °C
Steam mass flow: ~3,000 kg/h saturated steam
Electrical output: ~65 kW
Electricity produced: ~382,000 kWh/a
CO2 saving: ~244 t/a
Set to work: Sept. 2012
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.
