CSM-K
Sizing and Selection of a
High Capacity Clean Steam Generator
Note: To meet the requirements of HTM 2010 and HTM 2031 it is recommended that the
feedwater entering the generator is a minimum of 85°C. We would recommend the use of the
CSM-PD preheat and degasser system.

Clean steam temperature
Sizing and selection example
A CSM-K is required to generate 1000 kg/h clean steam @ 4.5 bar g
(T2) with steam @ 9 bar g after the control valve (T1).
The water inlet temperature (T3) is 30°C
T1
Primary steam temperature
From Table 1:
The water corrective factor @ 30°C = 1.1
Consequently, the steam load = 1000 kg/h (T2) x 1.1 = 1100 kg/h
T3
Table 1 Corrective factor for water inlet temperatures
From Steam Tables:
T1 (primary steam pressure) at 9 bar g = 180°C
T2 (clean steam pressure) at 4.5 bar g = 156°C
T1 - T2 = 24°C
