FRANCO TOSI MECCANICA - A COMPANY THAT HAS

ALWAYS BEEN A REFERENCE STANDARD IN THE POW-

ER GENERATION INDUSTRY - IS DEDICATED TO SERVE

YOUR THERMAL AND HYDRO POWER GENERATION

NEEDS WITH THE QUALITY AND ATTENTION YOU EXPECT

AND DESERVE. SINCE THE BEGINNING OF THE INDUS-

TRIAL AGE THE NAME FRANCO TOSI WAS CONSIDERED

A LEADER FOR RELIABLE TECHNOLOGY AND LEADING

EDGE DEVELOPMENT.

After a period of significant work abroad, particularly in

Germany, in 1876 the young engineer Franco Tosi was

called to Legnano to manage “Cantoni Krumm & C.”,

a steam engine and boiler manufacturer, which

thanks to Tosi’s work remarkably expanded its opera-

tions. Franco Tosi, an industrial pioneer, devoted him-

self to study and build reciprocating steam engines

that in a few years gained a reputation both in Italy

and internationally.

THE FIRST “TOSI ENGINE”, WITH A POWER OF 3 HP,

DATES BACK TO 1877 AND IN 1881 THE FIRST 40

TO 50 HP RYDER STEAM ENGINE WAS PRODUCED.

Tosi’s entrepreneurial vision and undisputed design

skills found their accomplishment with the advent of

the first power plants. His steam engines definitely

conquered both the domestic and the international

markets. In a few years Franco Tosi became a share-

holder and then, in 1884, the sole owner of a pio-

neer company in the energy sector that has borne his

name since 1881.

A name that still today is renowned all over the world.

Besides having excellent technical skills and being an

eminent industrialist, Franco Tosi was also a model

citizen who carried out outstanding philanthropic

work through his health insurance, social security and

professional training initiatives. An entrepreneurial

style whose signs are still visible and present today

in Legnano.

The industrial development of the Company “Franco

Tosi” followed the ups and downs of the European his-

tory in the early twentieth century, through two world

wars, the post-war recovery and the 1960s economic

boom including a strong internationalisation of the

Company’s markets.

FTM philosophy is to organize its product line in dif-

ferent standard turbine modules arranged alone or

together to tailor our solutions to customer specific

needs. Dedicated design solutions are thought to give

FTM steam turbines the best fitting to every market

range, from industrial to pure power generation.

SOME OF THEM:

• Back Pressure or Condensing Configuration

• Integral steam chest / Separated valve assemblies

(directly connected to cylinders or with pipe

connections)

• High back pressure LSB families

up to 5 m2 annular exhaust area

• LSB up to 9 m2 annular exhaust area (50 Hz).

• Fully 3D stator and rotor reaction blading for the

highest level blade path efficiency

• Any kind of controlled extraction

or induction / bleeding

• Skid supplied solutions (industrial), any

direction exhaust casings and high recovery and

efficiency axial ones

• Rotor Welding technology for optimized shaft

material combination

FTM has developed its product range through a stand-

ardized modular approach, in order to meet any cus-

tomer’s need with the same top-class reliability, effi-

ciency and flexibility.

The following table summarizes the typical technical

features of FTM steam turbines.

Type of machines described above are typical ar-

rangement of different standard modules which

can be combined in several possible solutions.

For example, the HIC / DL turbine is made by one HI

module (High pressure and Intermediate pressure sec-

tions combined in the same cylinder) + one DL mod-

ule (Double flow Low pressure cylinder). On the other

hand, a backpressure turbine with reheat can be ob-

tained by utilizing only an HI module.

Note: grid frequency 50/60Hz for all models except DHI/DL-ML (50Hz)

S C F1 0 M W - 1 0 0 M W

Single flow, same flow direction for the entire bladed

path. Full arc admission with reaction blades as well as

control stage version are available. Very simple me-

chanical scheme to meet the highest performance and

reliability standards of a wide and diversified market,

from industrial applications to geothermal needs. Small

nominal power turbines of this type are usually high

speed ones, with a gearbox for coupling with the gen-

erator.

Single flow, HP section flow in opposite direction to IP

and LP flow, single cylinder.

This turbine standard has been developed to answer

to needs of our customers both in the industrial and

utility sector. Full arc, fully reaction HP section version

is available as the control stage version, to fit any oper-

ational configuration.

Machine of this configuration may be realized with or

without reheat starting from the smallest sizes.

Two cylinders, single LP cylinder. This two cylinder con-

figuration, made by a high pressure AS module plus a

single flow (SL) or double flow low pressure turbine

(DL), covers with state of the art performance a broad

range of applications: typical are combined cycles, solar

and biomass with a high degree of flexibility in steam

conditions provided by different versions of the same

basic standard. Sliding pressure operations with full arc

admission is typical although control stage versions can

be supplied as well. This arrangement allows to choose

the optimal speed for each machine section, also set-

ting one turbine module on each side of the generator.

Configuration with two or three cylinders.

The first one is a combined HP and IP section, while the

second (and third, when needed) one is a double flow

low pressure module.

Usually these turbines have a reheat admission, and

a full arc HP admission when used in combined cycle

applications. This type of turbine is appreciated both by

utility and industrial customers when specific needs of

compactness are present in the medium power range.

sures the best efficiency and reliability, in USC configu-

rations if requested for coal / fossil fired plants and in

sub critical one for combined cycles as well. Full arc

admission and full reaction blading. This configuration

is made by an AS module for the High Pressure Turbine

plus one single (MS) or double flow (MD) intermediate

pressure module plus one (DL) or more (ML) double

flow Low Pressure Elements.

Customers choose FTM impulse type turbines because

of their extreme robustness, simplicity and operational

flexibility. Small nominal power turbines of this type are

usually high speed ones, with a gearbox for coupling

with the generator.
