Need a little advise. The steam power plant im working ats vacuum has dropped consistantly over the last week or so. Ive trended in/outlet condenser circulating temps, vacuum, load, gland seal steam pressure and temps etc. I cant get a hotwell temp on the trend so that out of the question. Would warn labrynth seals on the LP end of the turbine aid in the dropping vacuum? We havent had a turbine casing pulled in way too many years, so I have no clue.
