An important task of optimizing a steam system is to determine the most economical way to satisfy increasing and decreasing steam and power demands. This can be... 

Energy supply optimization is about generating steam and power at the lowest cost via optimizing boilers and turbines. At the same time, it is about optimizing power... 

Application Remarks The whole set of equations 19.10-19.38 forms the optimization model for steam and power. This optimization strategy allows the fastest dynamic response while always trending to the most economical steady state operating position. Furthermore, the steam marginal prices will be automatically determined from the optimization model (Varbanov et al., 2004). 

An example of where the utility optimization solution was applied was at a petrochemical site in Korea. The plant had three oil-fired boilers and three backpressure steam turbines that provide steam and power to the process units, and also supplied excess power to the national grid. The solution used the combustion...

In energy terms, industries of sugar and alcohol are sustainable, in which about 90% bagasse (calorific power 18.322 kJ kg ) is used however, the consumption can be reduced for 70% if the system of steam generation was optimized. Straw can also be mixed to the bagasse to be burned because of high calorific power (18.870 kJ kg ) [2] but with the drawback of producing more ashes.
