PTC 4, on Fired Steam Generators, is the ultimate comprehensive document for defining, calculating and testing for the efficiency of Fired Steam Generators by the Energy Balance Method as well as other significant performance parameters.
What is PTC standard?
PTC 6, on Steam Turbines, is the international standard for steam turbine acceptance testing. … It provides a standard, consistent, method for determining existing, retrofitted and new steam turbine performance within the minimum practical uncertainty.
What is performance test in mechanical engineering?
Performance test codes, otherwise known as PTCs, are standard documents, written and published by the American Society of Mechanical Engineers (ASME), that provide uniform rules and procedures for the planning, preparation, execution, and reporting of performance test results for different instruments, equipment, and …
What is the performance test code for steam turbine performance testing?
PTC-46, Power Plant Performance Test Code (1996), is routinely implemented in combined-cycle facilities. … A committee was formed in 2000 to develop a new PTC-6.2 dealing exclusively with steam turbine performance in combined cycles. A new and comprehensive Measurement Uncertainty Code, PTC-19.1, was issued in 1998.
What is the Performance Test Code for pump performance testing?
PTC9 – 1970 (R1997) – Displacement Compressors, Vacuum Pumps and Blowers. PTC10 – 1997- Test Code on Compressors and Exhausters.
What is enthalpy drop test?
Enthalpy Drop Test. The Enthalpy Drop Test is used frequently for monitoring steam turbines. This test involves a minimum number of instruments, but estab- lishes the efficiency of those turbine sections most susceptible to deterioration.
What are steam turbines made of?
The nickel-based blades are alloyed with aluminum and titanium to improve strength and creep resistance. The microstructure of these alloys is composed of different regions of composition.
What is the full form of ASME?
The American Society Of Mechanical Engineers.
How do you test the performance of a steam turbine?
In steam power plants and combined cycles, the test of the steam turbine performance is tightly bonded to the proper operation of the boiler. Feed water mass flow measurement, using suitable flowmeters as prescribed by ASME PTC 6 Code, is recommended for an accurate evaluation of the steam turbine efficiency.
How do you evaluate pump performance?
The performance of a pump can be measured using 3 main analytical models; flow rate (Q), head (h), and efficiency (n). These 3 models allow users to gain an overall sense of how the pump is performing during operation.
What is the test medium for pumping performance test?
The testing is done on the test bay of the manufacturer. Only pure cold water with a density of ρ= 1 kg/dm3 is used as the test medium. Pump block units are normally tested with installed motor.
How do you check pump speed?
To check if your pump is operating efficiently, measure the power consumed by the pump and check it against the pumps performance curve. The pump curve will specify how much power you should be using at the flow and pressure your pump is generating. This helps you to identify which pumps are not operating efficiently.
What is the blade speed ratio of impulse turbine?
Explanation: Blade speed ratio (ρ) is the ratio of blade speed to the steam speed at the entrance of the moving blade. For maximum efficiency blade speed ratio should be half of the cosine of the nozzle angle. 5.
Why do we reheat steam?
Why Reheating of steam is used? Explanation: Work output = work done by turbine – work done by compressor. Explanation: Since work output increases the steam rate decreases. Explanation: Efficiency = work output / heat supplied, heat supplied is less in this condition only.
What is the purpose of a draft tube?
The draft tube is a conduit which connects the runner exit to the tail race where the water is being finally discharged from the turbine. The primary function of the draft tube is to reduce the velocity of the discharged water to minimize the loss of kinetic energy at the outlet.
What are the two types of steam turbine?
Two types of steam turbines must be considered, condensing and noncondensing.
What is Casing in steam turbine?
Steam turbines consist essentially of a casing to which stationary blades are fixed on the inside and a rotor carrying moving blades on the periphery. The rotor is fitted inside the casing with the rows of moving blades penetrating between the rows of fixed blades.
Is ASME a government agency?
ASME standards are therefore voluntary, unless the standards have been incorporated into a legally binding business contract or incorporated into regulations enforced by an authority having jurisdiction, such as a federal, state, or local government agency.
Who governs ASME?
Board of Governors ASME’s affairs are managed by a Board of Governors (BOG) chosen from its membership.
What is the use of ASME?
The aim of ASME is to promote art, science and allied science and the practice of mechanical and multi-disciplinary engineering. ASME has developed several codes and standards to enhance public safety and productivity of Engineers.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
