Heatrate is the term used in power industries to check how efficiently the plant is running. its unit is kilo calories per kilowatt hour..= Kcal/Kwh or in a shortcut method, the HR can be directly calculated by using the formula = Specific fuel consumption * Calorific value

What tax rate increases as the tax base increases?
The progressive tax rate is one where the tax rate increases as the taxable rate, or income, is increasing.
Will you rate my SS team?
ok ill rate your team
How fast is jimmy johns?
First you must find the definition of fast then we must calculate the rate of awesomeness at which they fall because they do make their sandwiches in the sky so technically if you were to go through all this boring math and stuff your calculator would come out with, yes freaky freaky fast.
What is the catch rate for a timer ball?
The Timer Ball's base catch rate is 1. After every 10 turns, the catch rate increases by 1, but the maximum is 4.
When was Rate Furlan born?
Rate Furlan was born on March 9, 1911, in Padua, Veneto, Italy.
What is heat rate of steam turbine How to calculate heat rate of steam turbine?

Steam turbine heat rate formula?
The efficiency of a steam turbine is just the ratio of power out to power in, but if you want to be able to calculate it from the basic mechanical design, this is a specialised topic. In the link below is a general description of steam turbines, in the references and additional reading list there are some references that may help you.
How do you calculate the gross heat rate of a turbine?
Divide heat added to the boiler between feedwater inlet and steam outlet by the kilowatt output of the generator at the generator terminals. Rate expressed in btu. See article.

How do calculate heat rate turbine gas?
Turbine cycle heat rate is a measure of the turbine efficiency. It is determined from the total energy input supplied to the turbine divided by the electrical energy output. The energy input is the difference between the energy in the steam supplied to, and leaving from the turbine. The total energy supplied is the sum of the steam mass flow rates to the turbine multiplied by their respective enthalpies. The energy leaving is the sum of mass flow rates exiting the turbine multiplied by their respective enthalpies. Take the difference in the total energy supplied and leaving, divide by the electrical output and this gives you heat rate, typically expressed in Btu/kWh or kJ/kWh. This is easy for a single source of steam passing through the turbine to a condenser, but gets a bit more tricky for reheat turbines with multiple extractions as all the streams in and out have to be accounted for.
How do you measure level of tank?
Steam Rate calculation Formula for Steam Turbine
How do you calculate steam consumption rate?
There are several ways to calculate the .steam consumption rate. First would be to use a heat transfer equation. Another way would be to measure steam directly using flow metering equipment.
Heat rate of gas turbine?
The heat rate of a gas turbine using petroleum is 13,622. On the other hand, gas turbines that use natural gas produce a heat rate of 11,499.
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.
Why the steam turbine needs preheating before the operating?
there are stages, fixed blades on the turbine shell and rotating blades on the rotor. They are very close together sooo, because the steam enters at one end of the turbine it heats that area first and it expands the metal there faster than at the other end causing it to rub. if you heat it slowly the turbine casing and the rotor grow at ~ the same rate so the stages don't rub together. If you heat too quickly,by just admitting a high volume of steam, the rotor heats up to fast, because of it has less metal to heat up, it rubs the fixed blades. this is called going long (the rotor is longer than the tolerances between the fixed blades on the casing)
What does steam do to a turbine?
Steam (under pressure) comes into contact with the blades of the turbine through which it is flowing and, by the direct application of force, causes the blades to move, turning the turbine shaft. The turbine coverts the thermal energy of the steam into (rotating) mechanical energy. Surf on over to our friends at Wikipedia using the provided link and get more info. Oh, and check out the pics! Answer it depends what type of turbine one is using types of steam turbine 1 impulse turbine 2 reaction turbine in 1 st one steam is completely expanded inside nozzle and all pressure energy get converted in to kinetic energy using this impulse force turbine runs. in 2nd steam is multiple stage blades are used where high pressure superheated steam gets expanded inside the turbine in each stage and after each stage velocity of steam increases. very high temperature superheated steam is reaquired because it has very high specific volume which helps in reducing mass flow rate of steam.
