Boiler efficiency calculations - Heat Transfer

2005-1-11 · How would the boiler efficiency compare if the higher heating value of the gas was used in the calculation? 2. Also, you mention the eff. dropped off a little as boiler load moved above 75 or 80%. That is interesting - do you have data for a spread of loads - e.g. oxygen %, stack temp, ambient temp., feedwater temp?

Heat transfer, and the first law of thermodynamics

1998-6-17 · Thermodynamics. Thermodynamics is the study of systems involving energy in the form of heat and work. A good example of a thermodynamic system is gas confined by a piston in a cylinder. If the gas is heated, it will expand, doing work on the piston; this is one example of how a thermodynamic system can do work.
