Competences from a single source

ANDRITZ – Experts in hydropower


ANDRITZ – Experts in hydropower

Working Range of micro hydropower


ANDRITZ Atro Archimedean Screw

Archimedes invented the screw

pump 2300 years ago

ANDRITZ Atro designs and builds

screw pumps for decades


ANDRITZ Atro hydropower screw as a turbine

ANDRITZ Atro invented the

hydropower screw 15 years ago

The genius principle is turned

around

The hydrodynamic screw is

placed inclined in flood direction

in the river

The water flow makes the screw

rotating.

The energy is given to

a generator via a gearbox

Do you want to invest into

renewable energy?

Do you have problems with the

interconnected grid,

• because there is none?

• because the power lines are to

weak?



… an owerflow over an existing dam?

… an irrigation channel?

… old unused hydropower site?

… a clean water outlet of sewage

treatment plants?

….


Do you have nearby …

… a natural river flow

with currents?


… at sites with small heads from

1 to 10 m

… at sites with flows from

0,25 to 10 cbm/sec.

=> Power output up to 500 kW

… at sites with concerns about

fish mortality

… with high efficiency especially at

partial load

… with small investments and

maintanence costs


Perfect micro hydropower utilisation …


Scoar screen

Shut down device

Drive unit with

gearbox and

generator

Control cabinet: AHC - ANDRITZ hydro screw controller

Archmimedean Screw

with upper and lower bearing

incl. splash plates and different types of troughs


Main Components


No danger of blockage due to big

passages

No need of expensive fine screening

Very fish friendly

Very low wear due to slow turning

screw


Advantages


Enviromental friendly, because of little

effects in the surrounding world

Minimal civil works

No deep excavating

Less regulations, smaller process of

permission


Advantages


High efficient turbine for

small heads 1-10 m

Flows from 0,25 – 10 cbm/sec.

Sites with concerns about fish

mortality

Trouble free operation at low

maintanence costs

Small investments in machinery

and civil works

Pumps as Turbines Series ACT / FPT / HPT

Applications, Performance Range

Design and Function

Advantages

References

Performance data:

Head: up to 80 m

Flow:

up to 800 l/s with ACT

up to 6000 l/s with FPT

HPT: Head up to 350m

Flow up to 250 l/s



Applications

Island stations for mountain refugees

Drinking water turbines

Waste water turbines

Reserved flow turbines

Micro power stations with supply to grid

Energy recovery turbines in industrial

applications

Small pump storage power stations


Our philosophy:

Use only in applications, where pump fits perfect as turbine !

Wear resistant execution

Little and easy maintenance

Impeller with large free passage

Low problems with clogging

Direct- or belt drive / gearbox possible

Serial production, short delivery time

Disadvantage: Pumps have only one optimum duty point

Advantages



Control of turbine


Casing works as rigid guide vane,

only one optimum point available

Control possibilities:

a) Throttle control

surplus flow: by-pass

b) Variable speed control

shifts optimum efficiency point


Main Components


Turbine

- Rigid design

- Speed optimized selection

Control valve

...for control, niveau regulation and

emergency shut down or as

closing valve during stand still.

Switch cabinet

- current distribution, fuses, control,

battery and warning systems

Generator

- asynchron (parallel to grid) or

synchron (island drive)

Control valve

-with 24VDC drive

-for flow control and

-emergency shut down

Generator

Asynchron (parallel to grid)

Synchron (island drive / off grid)

LV-switchbox

-current distribution

-fuses

-control unit

-battery
