2003年11月26日 · At the risk of repeating myself: from the data supplied at 100 MW and at 200 MW, the loss of vacuum is due, at least in part, to vacuum equipment deficiencies in removing noncondensables (partly generated by deteriorated turbine shaft seals), and part due to poor heat transfer in the surface condenser by insufficient surface and other possible ...

2005年12月4日 · If you only wish to determine the heat load to the condenser , there are several simple methods and also some complex methods( as used in performance tests). For the water cooled condenser, you could measure the cooling water inlet and outlet temps and estimate the water flow based on the circulating pump performance curves and the monitored ...

2009年2月23日 · I am designing an air cooled heat exchanger for a steam condenser. The specs that i have recieved for steam is a flow rate of 99,800 lb/hr, 969.89 BTU/lb, and at 4.6 inHg. The heat load given is 86,958,734. The heat load was calculated by the flow rate times the difference between the enthalpy...

2011年7月28日 · If separate drain cooling plate heat exchanger used, with intermediate condensing zone outlet reservoir, then cascaded drain can enter intermediate reservoir. - inert gasses removal ANS: If using a plate HX for condensing without condenser zone outlet reservoir, venting cannot be achieved unless condensate level is maintained mid-way between ...

2013年4月2日 · The condensing steam heat transfer coefficient is relatively high, such that the main resistances to heat transfer are the fin efficiency and the air side heat transfer coefficient, and one could nearly ignore the resistance due to steam condensation, but with a resisstance due to a liquid film barrier added.

2012年2月16日 · A thermal engineer I work with designed a LPG Condenser Air Cooler and I have a few questions regarding the manufacturing of the unique design. The unit is 36' long with 6 passes/6 rows, Cstl, plug box header. The temperature inlet/outlet split are 500/109 F. There are two bays in parallel...

2001年11月6日 · A: I am quite familiar with your problem and from what I have seen you have one of two problems, possibly two. In the normal course of making heat your heat-pump gets cold and WILL make ice depending on outdoor temperature and humidity. The textbooks all say that most ice production is produced at 40 degrees F.

2019年5月14日 · When installing any condenser, Level transmitter and control valve are manatory ones, Aren't they? Please inform this one! I am a heat exchanger engineer. Baffle is horizontal cut one in my fig. But, I know well the vertical cut of baffle is …

2003年1月22日 · The key point the "jsteverm" is correct about is that the effectiveness of the heat transfer (a condenser is, of course, a heat exchanger) is greatly diminished when air is introduced into the condenser. This is essentially the entire point. This is why you can raise the condenser pressure by bleeding air into the condenser.

2009年3月2日 · Each heat transfer zone has its own heat transfer coefficient and LMTD. The overall LMTD and coefficent are normally weighted. The question of HOW they are weighted really depends on the way the exchanger is built. If it's a single-pass condenser, then it's pretty simple: Just treat each portion of it as a defined length.
