with. heat recovery steam generator systems for process steam supply requires reliability and availability to be as high as possible. Therefore independant operation of boiler to supply the process steam when the gas turbine is tripped or out of operation for maintenance is advantageous. The integration of gas turbines and heat recovery steam
For systems larger than 150,000 sq ft EDR, 10-minute net storage is better, because steam takes longer to travel through the entire system and return as condensate. Recall that 1 minute net storage is 1 minute based on pumping capacity, which is really twice the steaming rate of the boiler.
Other than a Steam Turbine, there are some associated systems in a power plant. These Systems are required for running of a turbine. They are * Oil System * * Lubricate the bearings * cool bearings * flush out metallic debris from bearings * cont
An online model has been installed to monitor and optimise the energy system, using technology that has been applied successfully by Repsol in similar projects.1-4 A detailed model of the steam, fuels, electricity, boiler feed water and condensate systems has been assembled, including all interactions between these systems, as well as real
Heating: steam inc to heat exchanger to flashtank w/cold water injection to sewer. Some buildings only use steam for heating while having electric boilers for domestic hot water. For those particular systems there is lots of condensate that gets dumped just wondering if there is something that can be done with all that energy.
A steam preheat assembly is recommended if the blended makeup/condensate return temperature is lower than 140F. This component includes a self contained temperature control valve, check valve, and copper sparge tube to evenly distribute the steam under the water line of the feedwater system. ELECTRICAL OPTIONS.
A method to avoid phosphate or caustic chemistry issues is to employ full-flow condensate polishing, which provides a barrier of protection for the steam generators and allows simplified boiler
The boilers are normally located in a separate auxiliary boiler house as shown in Fig 2.88 and are arranged to each supply steam into a ring main distribution system; condensate is returned via a separate system to recovery tanks adjacent to the auxiliary boilerhouse.

The expelled hot gas needs to drive another turbine, so the exhaust is passed through a HRSG, which creates superheated steam that drives a downstream steam-turbine. The turbine can either drive a generator (combined cycle system) or just use the steam in process applications (cogeneration or combined heat and power (CHP)).
Condensate treatment or condensate polishing is often the major portion of the water treatment plant; the spent steam from the turbine is usually condensed. Most high-pressure boilers (70 bar g) deploy a condensate polishing IX system to minimise problems associated with corrosion products such as iron and copper.
in two heat recovery boilers fired by the sulfur in acid plants #3 and #4. The steam from plant #3 is used to drive a turbine powered blower, and the steam from plant #4 is used to gener-ate electricity from a steam turbine generator set. Exhaust steam from these two turbines is used for process heat. This process steam is
Steam-condensate thermal engineering systems are applied in numerous industrial sectors. A scheme of a simple open conventional steam-condensate system is given in Figure 5.6.The steam produced in the boiler house is transported via pipelines to the heat consumers (heat exchangers; heat apparatus), where the steam condenses. At the exit of the heat exchangers, condensate batteries
Plants with drum-type steam generators — both conventional boilers and heat recovery steam generators (HRSGs) — maintain steam purity by taking advantage of the physical separation that occurs between water and steam in the drum. As the water boils, it forms a steam-water mixture, which upon entering the drum separates into steam and water.

The steam turbine is a device for obtaining mechanical work from the energy stored in steam. Steam enters the turbine with a high energy content and leaves after giving up most of it. The high-pressure steam from the boiler is expanded in nozzles to create a high-velocity jet of steam. The nozzle acts

Condensate Control One of the most important pieces of equipment in a power plant is the condenser. The condenser is responsible for providing a high vacuum environment where turbine exhaust steam can be condensed and where condensate can be collected and returned to the steam generator.
12. Boiler feed pump. Usually steam driven, this pump draws condensate from the condensate tank and discharges the condensate at high pressure through the economizer where hot exhaust gasses from boiler heat the condensate. This condensate then enters the boiler water drum via a feed regulating valve (which controls the water level in the water

Function of condenser in a feed system for boiler and steam turbine ; 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. The feed system completes the cycle between boiler and turbine to enable the exhausted steam to return to the boiler as feedwater.
Steam Pressure Reduction: Opportunities and Issues Boiler Blowdown Loss When boiler pressure is reduced, the blowdown loss is also reduced. If the energy from blowdown is being recovered through a blowdown heat recovery system, there will be no further savings by reducing the boiler pressure.
