For the steam supply pipe network that has been put into operation

the amount of condensed water is affected simultaneously by factors such as steam flow

steam pressure

steam temperature and ambient temperature. To explore the relationship between the steam supply pipe network and these influencing factors

this paper takes a steam supply pipe network as the example

with the help of the Gensystem model development platform

it establishes a pipe network simulation model

and obtains the relationship between the pipe network condensate and its influencing factors. Moreover

it analyzes the dynamic change trend of the condensate volume when the influencing factors are disturbed. The results show that

under the conditions with steam supply flow rate of 8.33 kg/s(30 t/h)

steam supply pressure of 1 MPa

steam supply temperature of 280 ℃ and ambient temperature of 20 ℃

for every 2.78 kg/s(10 t/h) increase of the steam supply flow

the condensate quantity of pipe network decreases by 33.3%. For every 0.1 MPa increase of the steam supply pressure

the condensate quantity of pipe network increases by 24.0%. For every 10 ℃ increase of the steam supply temperature

the condensate quantity of pipe network decreases by 7.1%. For every 10 ℃ increase in the ambient temperature

the condensate quantity of pipe network reduces by 6.8%. The condensate quantity of the pipe network is highly sensitive to the steam supply pressure. When the steam supply pressure increases

the condensate quantity of the pipe network will increase rapidly in a short period of time

and a large amount of condensate is prone to accumulate and cause safety hazards.
