Steam turbine - sudden temperature change
Steam turbine - sudden temperature change
(OP)
Hi,
I'm looking at having two boilers connected in parallel that are delivering steam at different temperatures. If one of the boilers trip, I get a sudden drop in mass flow and a sudden change in temperature of the live steam. Would any turbine specialist be so kind to give some guiding values to how big a temperature change the turbine could handle?

RE: Steam turbine - sudden temperature change
On another note when we are starting up we have some temperature limits, once our inlet flange metal temps reach about 680* we can increase rapidly. Before this temp we have temperature ramp rate that cannot be exceeded.
Hope it helps
