CSM-PD

Pre-heating and Degassing System

for use with Clean and Pure Steam Generators

Description

The pre-heating and degassing packaged system is available in

several tank capacities enabling suitable feedwater to be supplied

for clean and pure steam generators up to a steam production rate

of 4200 kg/h. Larger capacities are available upon request.

The unit comes tested and ready to commision once connected

to available services.

Available types

CSM-PD500 Shell capacity 500 litres (working capacity 370 litres)

CSM-PD1000 Shell capacity 1000 litres (working capacity 700 litres)

CSM-PD2000 Shell capacity 2 000 litres (working capacity 1 400 litres)

CSM-PD packages are also available using superheated water

as the primary heating medium. Details are available on request

from Spirax Sarco.

Applications

The use of a pre-heating and degassing unit, for use with feedwater

in unfired clean or pure steam generators solves a number of

problems, reducing the life cycle costs of a steam generation

system. In these systems chemicals cannot be used for treating

or degassing the feedwater and therefore 'thermophysical/

mechanical' systems are used instead, such as pre-heating of the

generator feedwater to a temperature above 85°C.

Principal features:

- External heat exchanger

- Microprocessor feedwater control

- All components in contact with clean water are stainless steel
