#TURBINE THERMODYNAMICS CALCULATOR GENERATOR#

We’ll discuss the importance of enthalpy in more detail next week, when we’ll apply the concept to the work output of a steam turbine. In terms of the illustration below, W stands for work, or potential for useful outcome of the turbine/generator process in the form of electricity, h 1 is the enthalpy of the steam entering the inlet of the turbine from the superheater, and h 2 is the enthalpy of the steam leaving at the turbine exhaust. This relationship is represented by the following equation, In other words, the work leads to a useful outcome. What is meant by work is the act of driving the electrical generator, which in turn provides electric power. When it comes to steam turbines, thermodynamics tells us that the amount of work they perform is proportional to the difference between the enthalpy of the steam entering the turbine and the enthalpy of the steam at the turbine’s exhaust. Conference on Turbomachinery: Fluid Dynamics and Thermodynamics, Prague. Now, let’s see why this property is important with regard to the operation of a steam turbine. 1) when applied to the calculation of transitional flows on turbine blades. If we decrease P, the result will be a decrease in h. Once these parameters are known, enthalpy drop in each stage can. Looking at the equation above, simple math tells us that if we increase the pressure, P, the result will be an increase in enthalpy h. As initial velocity is known to you, kinetic energy supplied to the turbine can be calcuated.

For the purposes of our discussion, it’s the amount of pressure that steam places on pipes containing it. Pressure is force per unit area and is measured in psi, pounds per square inch. The flow of water under pressure turns a turbine that is coupled to a generator. Where u is the internal energy of a substance, let’s say steam P is the pressure acting upon a specific volume, v, of the steam and P and v are multiplied together. to panic, we will use only what we need to know to calculate Total Head. Enthalpy is a key factor in thermodynamics, and is commonly represented in engineering calculations by the letter h and denoted as,

As discussed in a previous blog article, thermodynamics is the science that deals with heat and work present within processes. Step 4: Calculate Steam Turbine Energy Out and Generation (Power Out) Energy Out ( Inlet Specific Enthalpy - Outlet Specific Enthalpy) Mass Flow Power Out Energy Out Generator Efficiency Assumptions Inlet Mass Flows equal Outlet Mass Flow. The term enthalpy was first introduced by scientists within the context of the science of thermodynamics sometime in the early 20 th Century. For the purposes of our discussion, that would be the heat energy contained within steam which flows through the turbine in a power plant. This vacuum plays a key role in increasing steam turbine efficiency because it affects a property known as enthalpy, a term used to denote total heat energy contained within a substance. Last time we learned how the formation of condensate within a power plant’s turbine results in a vacuum being created.
