Gland condensers
0 likes670 views
Gland condensers are small heat exchangers that condense steam from turbine shaft seals to prevent water accumulation in lubrication systems. Sealing steam injected into shaft seals and steam leakage from high pressure ends can leak out toward bearing housings. Gland condensers apply a slight vacuum using cooling water to condense this steam to water to reduce this leakage and draw water away from lubrication systems.

DeaeratorInfopitaara
油
A deaerator provides NPSH to booster pumps, removes gases from feed water, and acts as a heat exchanger. It works by spraying thin films of feed water into a steam atmosphere, quickly heating the water to saturation and reducing the solubility of dissolved gases based on Henry's and solubility laws, so the gases are released and vented from the deaerator. There are two main types - tray and spray deaerators. Spray deaerators are more effective at removing oxygen and lowering gas concentrations through their increased surface area contact between the thin films of water and steam.Heat rate of thermal power plant

Flash steam is formed when high pressure condensate experiences a rapid drop in pressure, causing some of the condensate to flash into steam. Flash vessels are used to separate flash steam from condensate. They allow condensate to fall to the bottom where it drains out, while flash steam collects at the top and is piped to low pressure steam equipment. Recovering flash steam improves boiler efficiency and increases steam generation. It also provides economic benefits through reduced fuel costs and lower water-related expenses.Different types of stream traps

Steam condensers are heat exchange devices that condense exhaust steam from turbines or engines using circulating cooling water to condense the steam, allowing the steam's latent heat of vaporization to be recovered. There are two main types: surface condensers, where steam is condensed on the outside of cooling water tubes, and jet or direct contact condensers, where steam directly mixes with cooling water. Surface condensers produce higher quality condensate that can be reused as boiler feedwater without treatment, while jet condensers are cheaper but require treatment of the condensate. Proper condensation improves thermal efficiency and reduces operating costs by recycling condensate to the boiler.DRY-GAS-SEAL.ppt dgs details has been given to be seen

The document outlines the advantages and operational guidelines for dry gas seals, which provide improved sealing with minimal maintenance and reduced emissions. It explains the function of primary and secondary seals, their gas supplies, and the importance of monitoring seal performance through leakage trends. Key operational guidelines include avoiding reverse rotation and ensuring proper gas supply quality and flow to maintain optimal seal performance.Superheated vs saturated Steam - chemical plants

The document discusses the differences between superheated and saturated steam, emphasizing their enthalpy values and implications for boiler performance and steam systems. Superheated steam offers advantages such as reduced condensation in pipelines and the ability to operate at higher velocities, but saturated steam is cheaper for heat exchangers due to better heat transfer coefficients. Desuperheating, the process of converting superheated steam back to its saturated state, is also explained, along with its types, which include indirect and direct contact methods.Excess air

The document discusses excess air and heat distribution in boilers. It explains that excess air above the theoretical minimum is needed for complete combustion due to imperfect mixing of fuel and air. Typical excess air values range from 5-60% depending on the fuel and furnace type. Heat distribution systems discussed include steam radiators, which use steam piped through the home, and hot water radiators, which can be zoned to improve efficiency. Regular maintenance of radiators includes bleeding air and cleaning/replacing steam traps and air vents.destillation tower in detail describing each part in the tower .ppt

The document discusses the theory and components of a modern vehicle cooling system. It aims to maintain engine temperature between 180-230属F. Key components include the water pump, radiator, thermostat, pressure cap, and hoses. The thermostat regulates coolant flow and keeps the engine from overheating when hot or underheating when cold. The pressure cap pressurizes the system to raise the boiling point of the coolant. Together, these components work to efficiently transfer heat from the engine to the outside air through the radiator.Steam distribution system by Varun Pratap Singh

The document discusses various types of steam traps used in steam distribution systems, including liquid expansion, balanced pressure, and bimetallic steam traps, detailing their operating principles, advantages, and disadvantages. It highlights the importance of proper temperature and pressure management in preventing waterlogging and maintaining system efficiency. Additionally, the document addresses issues like water hammer and flash steam, providing insights on mitigating these challenges in steam systems.Cooling

The document discusses engine cooling systems. It notes that only 20% of engine heat is used as power, with 35% transmitted to cylinder walls, causing inefficiency. It describes the need to prevent this heat transfer to cool engines. It then outlines different cooling methods, specifically air cooling and liquid cooling. For liquid cooling it discusses thermosiphon and pump systems, and components like the water pump, thermostat, radiator, and radiator cap. It concludes by discussing the use of antifreeze solution and how corrosion and scale buildup are managed.Steam traps
Steam trapsKarnav Rana

Steam traps are automatic valves that drain condensate and non-condensable gases from steam systems without allowing steam to escape. There are several types of steam traps that operate using different mechanisms: mechanical traps use float devices or inverted buckets, thermostatic traps detect temperature differences, and thermodynamic traps use pressure changes from steam flashing to condensate. Proper steam trap selection depends on the application needs such as venting air, operating pressure, load size, and resistance to freezing or dirt.Steam Blow

Blowing steam lines is done to remove foreign matter from equipment and piping after erection. It involves heating and cooling cycles from steam flow to loosen debris. Target plates are used to monitor cleaning, with stainless steel plates for final blows until plates show no pitting from debris. Procedures involve gradually opening and closing valves while maintaining pressure or rapid opening and closing to induce thermal shock for cleaning. Safety precautions must be followed regarding piping supports and exhaust direction.Refrigeration and Air Conditioning

Gland condensers
- 1. Gland Condensers Small heat exchanger used to condense the steam that leaks past the first section of seals on the shaft of a steam turbine. Specifically, if the turbine exhausts into a vacuum system, it is necessary to inject sealing steam into the seals in order to keep the low pressure end of the turbine from drawing in atmospheric air. This sealing steam from the low pressure end and the normal leakage from the high pressure end would tend to leak out and blow toward the bearing housing. In order to reduce the chance of this leakage causing an accumulation of water in the lube oil system, we use a gland steam condenser to draw a very slight vacuum (typically 2 or 3 in-Hg) at the outer section of the shaft seals. The gland condenser uses cooling water to condense this steam to water which is usually lost to sewer.
