    Steam boiler

    I think boiler have some fire to produced steam, and I didn't see and fire in the diagram.
  2. Torque (also called moment — mostly by engineers) is calculated by multiplying force and distance. The SI units of torque are newton-meters, or N*m (even though these units are the same as Joules, torque isn't work or energy, so should just be newton-meters). In calculations, torque is represented by the Greek letter tau: τ. Torque is a vector quantity, meaning it has both a direction and a magnitude. This is honestly one of the trickiest parts of working with torque because it is calculated using a vector product, which means you have to apply the right-hand rule. In this case, take your right hand and curl the fingers of your hand in the direction of rotation caused by the force. The thumb of your right hand now points in the direction of the torque vector. (This can occasionally feel slightly silly, as you're holding your hand up and pantomiming in order to figure out the result of a mathematical equation, but it's the best way to visualize the direction of the vector.) The vector formula that yields the torque vector τ is: τ = r × F.
  3. is it possible increase extracted steam from steam turbine?
  4. What kind of energy output is obtained from a ‘Steam Power Plant’?
  5. Exactly Alfredo Borba by using online application we can get the exact information.
  6. A very nice and informative post. Thanks for sharing.
  7. Turbine is a rotary mechanical device which extracts energy from fluid flow converts it into useful work. It work on simple principle the energy from fluid flow turns the three propeller like blade around the rotor which is connected to the main shaft that spin the generator which produces electricity.
  8. Log Mean Temperature Difference or LMTD is the driving force for the amount of exchanged heat by a heat exchanger. LMTD approach is quite straight forward and simple. But this approach cannot be used for the cases, where phase change occurs in the heat exchanger. Also, if the specific heats of the fluids change then the LMTD approach cannot be used.
