Maintenance is the key to active machinery.

Topic_0002 A turbine governing system is a control system that is used to regulate the speed and output of a turbine, such as a steam turbine, hydraulic turbine, or gas turbine. The governing system is responsible for ensuring that the turbine operates at a constant speed and responds to changes in load demand or operating conditions. The governing system typically includes sensors to measure the speed and load of the turbine, as well as actuators to control the flow of steam, water, or fuel to the turbine. The system uses this information to adjust the turbine's output to maintain a constant speed or to respond to changes in demand.

Steam turbine steam turbines convert heat from pressurized steam into mechanical energy. The turbine steam path converts thermal energy into mechanical energy through a series of stages that capture the momentum from the expanding steam. The Rankine cycle is a fundamental principle in the operation of steam turbines. The Rankine cycle is an idealised thermodynamic cycle of a heat engine that transforms heat into mechanical work during a phase transition. There are two basic types of steam turbines. The impulse stage is best suited for high-pressure region and for small steam quantities. The reaction stage is advantageous at the lower pressure region, where a large volume of steam must be handled. Sir Charles parsons British engineer patented steam turbine. Turbine has fixed and moving blades . Impulse turbine uses steam impinging upon the turbine rotor blades to rotate the turbine rotor. The velocity of steam is increased using nozzles. Compounding of steam turbine pressure, velocity, pressure and velocity compounding. Reaction turbine uses reaction force of steam to rotate the blades.

Experience Sharing Today, let's talk about turbines and ejectors. They don't normally come together, but that's because there are 2 kinds of system that either require an ejector, or it does not require one. The 2 kinds of system are called backpressure turbine and condensing turbine. A backpressure turbine implies that there is no condensing of the steam exiting the turbine, but a condensing turbine does. But why condense the steam? Here, we need to refer to the steam tables, and remember that the latent heat of condensation is a lot, lot higher per mol of steam. Which means, there is a lot of energy you can extract from here. Here is where an ejector comes into picture. Ejectors are meant to create a vacuum condition within the condensers (sometimes called surface condensers) so that it will be easier for steam to condense due to pressure and temperature difference, rather than relying on temperature difference only. Vacuum is created from ejection of non-condensable gases in the exiting steam. This creates a Joule-Thomson effect, and combined with cooling water flows within the tubes, brings the steam down to its dewpoint to effectively condense the steam. Here's the best part. This cannot be achieved if the vacuum condition is altered. Hence, ejectors plays a crucial part in ensuring the vacuum condition is always sustained. For that, a condensing turbine usually will have a main ejector and a hogging ejector. The main ejector is always running, but the hogging ejector doesn't (supposedly). In my RCA sharing previously, I mentioned about the leak in one of these ejectors, but how I was not able to gain insight from PI data readings during the trip. Let me know what do you think which ejector was I referring to, and why wasn't I able to gain insights from PI reading. I'd love to hear from you! In my next sharing, I'll share some data, and my personal thoughts as to why. Until then, happy Thursday! #processengineering #rootcauseanalysis

Distinguished Sir, Why is staging crucial to a steam turbine? High pressure and temperature are present in the superheated steam. As it expands and produces mechanical energy in the first stage of the turbine, some of its temperature and pressure are lost. Because the steam is compressed, the first stage is often a turbine with a lower diameter. In order to handle the expanding steam and continue producing energy effectively, we must enlarge the turbine. Consequently, the turbine will be shaped more like a cone and get wider. not very effective to construct or operate. As a result, we reheat the steam, which enables the creation of a more miniature turbine for the second stage. If necessary, repeat this for the third stage. In order to chill the steam and condense it, a condenser will receive the last exhaust in the second or third stage, producing a vacuum. This makes it possible to lower the pressure drop more effectively while also keeping the steam from condensing in the last stage: If water droplets get within the turbine blades, they will damage them.?? Warm Regards, NK Tiwari
