Condensate pumps are used in hydronic systems that cannot discharge excess condensate water via a gravity feed. Condensate pumps are usually electrically powered centrifugal pumps . They are used to remove condensate water from HVAC systems that cannot be accomplished via gravity, and therefore the water must be pumped up.
Date: 6 and 7 July 1988: Time: Approximately 22:00 (first explosion)Location: Piper Alpha platform, Piper oilfield, North Sea (UK sector) Coordinates: 1]: Type: Explosion and fire: Cause: – Startup of a condensate pump that had not been mechanically isolated due to ongoing maintenance – Lack of protection by design of gas risers: Filmed by: Scottish Television: Deaths: 167: Property damage ...
The condensate pump then pumps the condensate water through a feedwater heater, which raises the temperature of the water by using extraction steam from various stages of the turbine. [5] [6] Preheating the feedwater reduces the irreversibilities involved in steam generation and therefore improves the thermodynamic efficiency of the system. [9]
Feedwater pumps range in size up to many kilowatts and the electric motor is usually separated from the pump body by some form of mechanical coupling. Large industrial condensate pumps may also serve as the feedwater pump. In either case, to force the water into the boiler, the pump must generate sufficient pressure to overcome the steam ...
Three views of a c.1885 steam trap. The general appearance of this arrangement is as in Fig. 1 or Fig. 3, the center view, Fig. 2, shows the cardinal feature of this trap, that it contains a collector for silt, sand, or sediment which is not, as in most other traps of the time, carried out through the valve with the efflux of water.
In two-pipe steam systems, there is a return path for the condensate and it may involve pumps as well as gravity-induced flow. The flow of steam to individual radiators can be modulated using manual or automatic valves .
Once you understand why a home might fail inspection, you can better formulate a repair plan. Here are 15 common things that may come up and what you can do to address the issues.
If this vent valve has not be opened sufficiently, the deaerator will not work properly, resulting in feed water with a high oxygen content going to the boilers. Should the boiler not have an oxygen-content analyzer, a high level in the boiler chlorides may indicate the vent valve not being far enough open.
