# How to calculate the steam turbine heat rate?

Station heat rate = Specific fuel consumption * Calorific value of fuel

Turbine heat rate = (Main steam flow * Main steam enthalpy + Aux Steam flow * Aux steam enthalpy - Feed water flow * Feed water enthalpy + Makeup water flow* Makeup water enthalpy)/Power generation

Unit of Heat rate is kcal/kWh, kJ/kWh,Mcal/MWh, MJ/MWh,

For kJ/kWh is 3600/turbine heat rate

Station efficiency = 1/ station heat rate for Kcal/KWh is 860/ station heat rate

For kJ/kWh is 3600/station heat rate

### How do you calculate turbine heat rate for re generative and reheat cycle turbine?

The steam rate (or heat rate, watering rate) is determined by taking the total heat or steam input and dividing the total KVa output of the generator. On a reheat turbine the heat input is the steam input at the throttle conditions PLUS the reheat addition from the reheater. The addition is determined by taking the steam heat content at the outlet from the reheater and subtracting the heat content at the inlet to the…

### 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 heat rate in power plant?

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…

### 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…

### 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…

### Why steam turbine heating required before starting?

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…

### Formula for calculating the heat balance for steam turbine hall?

The guaranteed heat rate, indicated on performance data table of power plant is calculated in accordance with the following formula: HR = (Qms x Hms - Qfw x Hfw + Qhrh x Hhrh - Qcrh x Hcrh - Qas x Has + Qmu x Hmu) x 3600 / W HR = heat rate [kJ/kWh] W = gross power output [kW] Q = mass flow [kg/s] H = enthalpy [kJ/kg] Subscript: ms = main steam fw…

### Difference between plant heat rate and turbine heat rate?

The turbine heat rate of a steam turbogenerato is the ratio of thermal input: power generated. It is often expressed in kJ/kWh. The efficiency of the turbogenerator is simply calculated from this. The plant heat rate is the ratio of fuel energy into the plant: power generated. It is greater than the turbine heat rate, because not all of the fuel's thermal energy can be captured by the boiler, and also power station services such…

### How does nuclear fission produce power?

Nuclear fissions produces power through smashing the particles of nuclear material apart with neutrons. This releases more neutrons which will hit more nuclear material, thus releasing energy. Energy=Heat. The nuclear rods control the rate of this interaction. The heat is then cooled by cold water, producing steam. The steam is then used to run a turbine, generating electricity.

### How does uranium turn the turbine in a power station?

Radioactivity produces a certain amount of heat, and uranium has the interesting property that you can increase its rate of radioactive decay by creating a certain density of specific isotopes (decaying uranium atoms emit neutrons which can be absorbed by other uranium atoms making them unstable, so that they too will decay). Therefore, uranium can be used as a source of heat - much like burning coal - and that heat can be used to…

### How does nuclear fission produce electric energy?

Nuclear fissions produces power through smashing the particles of nuclear material apart with neutrons. This releases more neutrons which will hit more nuclear material, thus releasing energy. Energy=Heat. The nuclear rods control the rate of this interaction. The heat is then cooled by cold water, producing steam. The steam is then used to run a turbine, generating electricity.

### How does a terry turbine work?

Terry was the name of a steam turbine manufacturer. The company was bought by Dresser-Rand some years ago. I don't think they sell this model now, only spare parts. The basic design is that of an impulse turbine (as opposed to a reaction turbine). The unique feature with Terry is the nozzles feed steam radially inward to a single rotating wheel with blading on the circumference. The blades are semi-circular so the flow path is…

### How steam required for steam tracing of jacketed lines is calculated how much steam required for sulfur melting?

The steam required for steam tracing is calculated on the basis of the amount of heat transfer that is required or the temperature that you want to maintain with the help of steam. It also depends on the pipe material through which the steam is passing,the condition of the steam that whether it is saturated or superheated etc. Overall heat transfer cofficient is calculated considering all the factors like fouling or scaling,inside and outside dia…

### How is resistance used in a space heater?

In an electrical space heater, electrical current dissipates energy into heat, and the heat radiates from the element. In a fuel powered space heater, an orifice throttles the fuel feed (resistance to flow), which controls the heating rate. In a steam powered space heater, an orifice throttles the steam (resistance to flow), which controls the heating rate.

### How is nuclear power generated into electricity?

A nuclear electrical power generating station is a jarring contrast in the levels of technology that work together. -- A controlled nuclear fission reaction is contained in a heavily isolated and protected core, where it continuously generates huge quantities of heat at a high rate. -- The heat is transferred to a liquid in pipes surrounding the core, and is carried away from the core. At this point, the technology steps back a couple of…

### How steam curing helps in faster curing of concretemortar?

Essentially what happens is that steam creates a "wet heat", both of which increase the curing speed of the concrete. The moisture speeds up the hydration process, whereas the heat increase the growth rate of the cement "crystals", leading to better adhesion to the aggregate and a faster early setting time and strength.

### Ranking cycle of water?

A binary geothermal power plant uses geothermal water at 160 c as the heat source. The cycle operates on the simple Ranking cycle with isobutene as the working fluid. Heat is transferred to the cycle by a heat exchanger in which geothermal liquid water enters at 160 C at a rate of 555.9 kg/s and leaves at 90C. isobutene enters the turbine at 3.25 Mpa and 147C at a rate of 305.6 kg/s, and leaves…

### How does temperature difference affect the rate of heat transfer?

For conductive and convective heat transfer, the rate of heat transfer is proportional to the the temperature difference; if you double the difference you will double the rate of heat transfer. For radiative heat transfer, the rate of heat transfer is proportional to the difference of the 4th powers of the absolute temperatures.
