Typical Application Consequences of spray water control valve’s failure ® Heat efficiency lose: due to the drop of throttle steam temperature caused by spray valve leakage, heat efficiency will be affected and extra heat will be needed for the boiler to keep the throttle steam temperature at the set point. ® Temperature contol: poor control of the steam temperature may also affect the high pressure steam pipe and turbine. ® When the pressure is higher than 12.4Mpa(1800psi), each temperature change of 19-22°C(34-40°F) would lead to 1 % heat efficiency change. ® Higher maintenance cost: frequent...
