In such case the condenser is known as a low level high vacuum jet condenser. See fig. 12-2.(b). A vacuum breaker which is a float control valve is provided just below the condensing cone. It prevents water from rising to too high a level in the condenser by allowing air to break the vacuum. (b) High Level Jet Condenser or Barometric Condenser
A vacuum condenser positioned after a process vessel, such as a still, evaporator or distilla-tion column, but before the vacuum system. In this issue, a precondenser is the process vacuum condenser. Intercondenser. A vacuum condenser situated between two stages of vac-uum producing equipment, for exam-ple, two ejector stages. Vent condenser.
The condenser is a heat exchanger which removes the latent heat from exhaust steam so that it condenses and can be pumped back into the boiler. This condensing should be achieved with the minimum of under-cooling, i.e. reduction of condensate temperature below the steam temperature.
A condensing boiler is not a compact fluorescent lamp (CFL); you can't simply plug it into a typical system and expect it to save energy. Selecting a condensing boiler is the easiest and least consequential part of designing a condensing boiler system. This paper provides basic principles for designing a heating system utilizing condensing
Mar 27, 2020 · The principle of this condenser is shown in the figure. The exhaust steam mixes up with the water and condensed. Condensate, cooling water and airflow downwards and are removed by two separate pumps known as an air pump and condensate pump.
Feb 21, 2017 · In this condenser, the steam enters at the bottom and flows in upward direction and meets with the down coming cooling water. Its working is similar as the low level jet condenser. The vacuum is created at the top of the condenser shell. With the help of vacuum and injector pump, the cooling water is moved to the top of the condenser.
There are exigencies (low lube oil pressure, fire etc) where the turbine post trip needs to be brought to standstill condition at the earliest. It is during these conditions that the vacuum breaker valve is operated. This operation resorts to atmo
Condenser for Marine Boiler Feed System & Steam Turbines
Condensing boilers in particular are designed to heat up your home and water as efficiently as possible. Not only is it now a requirement (as of 2005) for every newly fitted gas-fired boiler to be condensing, but it must also have an efficiency 'A' rating too.
mation in the vacuum condenser, increas-es the size and cost of the vacuum system, adds to the utility use of the vacuum sys-tem and causes the vacuum condenser to be larger. A well-designed process vacuum condenser will not have pressure drop of more than 10 percent of the operating pressure. Lower pressure drop is the
maximum in the boiler system 86.27% and then condenser and stack gas 13.73%. In addition, the calculated thermal efficiency principles. Steam surface condensers are the most commonly The exhaust steam from the turbine flows on the shell side (under vacuum) of the condenser, while the plant's circulating water flows in the Tube side
Basic Working Principle of Steam Condenser: the vacuum inside the condenser is created so that cooling water can circulate easily and also flow of condensate can be stabilized. So the extracted condensate can be reused in the boiler without any water treatment. Within the condenser space, there are several horizontal tubes, inside which
The vacuum energy vortex steam condenser has the advantages of simple operating principle, economic efficiency and applicability, high efficiency and energy saving, safety and reliability, simple construction and installation, convenience for operation and maintenance, stable operation, lower water consumption as compared to a wet cooling unit
The air extraction pump expels air from the condenser and creates a vacuum inside it. The vacuums create circulations of cold water and the flow of condensates downstream. As low-pressure steams comes in contact with cold water, it condenses and transforms into water.
If the condenser temperature is known, P s is found from steam tables and P c can be read from the vacuum gauge. ∴ We can write, P a = P c – P s Knowing the partial pressure of air P a its mass m a can now be calculated with the help of ideal gas equation P a V c = m a RT a where V c = volume of condenser; T a = temperature; R
Jan 22, 2019 · It basically takes out the latent heat of vaporization; from the gas mixture whether be steam or gas refrigerant to covert it back to liquid. Condenser that works under vacuum such as in boilers are called vacuum condenser; while the others working under normal or low vacuum condition are called atmosphere condenser.
Principle of Working of a Condenser: After passing through the hot well condensate is sent to the boiler. The design of a parallel flow jet condenser is quite simple when compared to other types of the jet condenser. Vacuum efficiency is quite low therefore there's a requirement of the pump to circulate water. The water pumps used
1) not enough vacuum, owing to poor working vacuum unit or high seawater temperature in the condenser, or an air leakage in the flanges owing to dry packing or loose flange bolts. 2) Boiler scale on the heater unit or even on the condenser, the last has also a bad influence on the vacuum.
