Gas turbine exhaust pressure loss negatively impacts performance by reducing the effective pressure ratio across the turbine. This loss can lead to decreased power output and efficiency, as the turbine has to work harder to achieve the same thrust or energy output. Additionally, higher exhaust pressure can result in increased back pressure, potentially affecting the overall system's thermal efficiency and contributing to higher fuel consumption. Managing exhaust pressure losses through design optimizations and control systems is crucial for enhancing turbine performance.

What is the effect of steam turbine control valve throttling in turbine efficiency?
In Boiler follow turbine mode , Boiler produces a constant pressure behind throttling valve and throttling valve adjusts necessary pressure and required steam as High Pressure steam for entering the turbine . In Valves Wide Open (VWO) mode the efficiency is maximum and we haven't any loss. (It's nearly 106% Turbine MCR) . In Turbine MCR , we have a little loss and consequently a little bit worse heat rate . In partial load , loss is more and efficiency worse.

The reheat factor in the steam turbine refers to the Thermodynamic effect on the turbine efficiency. Others factors includes the cumulative heat, and the steam turbine condition curve.
What is the effect or reheater in the gas turbine?
1.Turbine output is increased for same compressor work. 2.As more heat is supplied,thermal efficiency decreases.
What is the effect of silica on steam turbine blades?
Although several factors influence the formation of deposits on turbine components, the general effect is the same no matter what the cause. Adherent deposits form in the steam passage, distorting the original shape of turbine nozzles and blades. These deposits, often rough or uneven at the surface, increase resistance to the flow of steam. Distortion of steam passages alters steam velocities and pressure drops, reducing the capacity and efficiency of the turbine. Where conditions are severe, deposits can cause excessive rotor thrust. Uneven deposition can unbalance the turbine rotor, causing vibration problems.The nature of silica deposits found on turbine blades varies greatly. lists a number of silica compounds that have been identified in various studies of turbine blade deposition. Of these, amorphous silica (SiO2) is the most prevalent.Localized Silica Saturation. Turbine deposits are also formed where localized silica saturation occurs and silica condenses from the steam in those areas of the turbine. Partial evaporation of the precipitated silica can then occur with only a portion of the silica being dissolved by the continuous steam flow. Deposits remain as a result.Turbine Velocity. Another factor affecting the location of turbine deposits is the velocity in the turbine. Steam flows from the inlet to the outlet of the turbine in only a fraction of a second. Consequently, deposition is shifted downstream from the saturation point by the high steam velocities.Prevention of Silica DepositsThe most significant factor in minimizing turbine silica deposits is the maintenance of low silica concentrations in the boiler water. External treatment equipment must be operated carefully to limit the amount of silica entering with the makeup water, and the condensate must be monitored to minimize contamination. After silica enters the boiler water, the usual corrective action is to increase boiler blowdown (to decrease the boiler water silica to acceptable levels) and then to correct the condition that caused the silica contamination.

What spools the turbo in a diesel truck?
In a diesel and petrol vehicle the turbo turbine is spun via exhaust gases exiting from combustion from the engine. it takes a short amount of time for a turbo to produce boost because of the effect of waiting for combustion and exhaust gases to spin the exhaust turbine. but saying this the turbocharger creates no load on the engine, not like a supercharger which is belt driven off the crankshaft which means you have to give power to make power. two sides to the turbocharger featuring intake and exhaust. while exhaust gases spin the exhaust turbine, which is connected to the intake turbine it spins the intake side creating a vaccuum and compression of the intake air. so with more revs and more exhaust gas created it also increases boost or air intake at the same time.

Why used hogger and ejector in steam turbine?
A steam turbine condenser equipped with ejectors is usually fitted with two ejectors. The larger of the two is called the hogger and the smaller the huffer. Steam turbines are designed for efficiency and thus attempt to extract as much energy from the steam passing thru as is physically possible. Energy is extracted as both temperature and pressure decrease. The lower the temperature and pressure at the steam turbine's exhaust the more energy can be extracted from the steam. For this reason it is desirable for the steam turbine condenser (the exhaust) to be at the lowest temperature and pressure possible. The hogger, or hogging jet, is a large steam powered ejector that causes the steam condenser to operate under a near perfect vacuum whilst the steam turbine is in the start-up phase. In steady state operation the cooling effect of the condenser cooling water of the steam causes the condenser to operate under a nearly self sustained vacuum. The hogger is necessary in the start-up phase to prevent steam from condensing to water in the final stages of the turbine before the steam flow and cooling effect of the condenser can establish vacuum. The huffer or huffing jet runs continuously whilst the turbine is operating to remove any non-condensable gasses (i.e. air) that might leak into the condenser. It is nearly impossible to perfectly seal a condenser and turbine from air-in leakage. It should be noted that modern, large steam turbines do not employ steam ejectors to establish and maintain condenser vacuum. Modern designs utilize motor driven mechanical vacuum pumps.

How much does the exhaust effect on fuel consumption?
The exhaust system can significantly impact fuel consumption by influencing engine efficiency. A well-designed exhaust system enhances the expulsion of exhaust gases, which can improve engine performance and fuel efficiency. Conversely, a clogged or inefficient exhaust can restrict airflow, leading to increased fuel consumption as the engine works harder to operate. Overall, optimizing the exhaust system is crucial for achieving better fuel economy.
