As plant engineers focus on the effects of startup procedures and load cycles as a way of improving power plant efficiency, ABB discusses how its BoilerMax control software package can optimize steam generators' startup strategy.
Boiler Control: Steaming ahead with optimizing power plant boiler ... Jan 7, 2007 ... The prediction horizon is 60 to 90 minutes, covering the entire length of a boiler startup, up to the point where the turbine is rolled on steam.
Model-based online applications in the ABB Dynamic Optimization framework. ... Steaming ahead with optimizing power plant boiler startup. Article. ... The startup of a steam power plant serves as ...
Operational Experience with Startup Optimization for Steam Boilers Starting up economically BoilerMax is a predictive boiler load-margin com-puter implementing a nonlinear, model-based multi-variable controller for the purpose of online optimization of boiler startup procedures. This tool is capable of optimizing the fuel costs during startup.
Steaming ahead with optimizing power plant boiler startup Some of the ways by which BoilerMax control software package can optimize steam generators start up strategy are discussed. The control concept uses the principle of … BoilerMax - Optimize power plant start-up (English - ABB BoilerMax Optimize power plant start-up … steam headers).
In markets where steam power plants (i.e., fossil-fired boiler with steam turbine) still run at full capacity, optimizing performance to eliminate unplanned downtime, meet regulatory burdens and increase power output are still priorities that must be met, offering significant improvements in profitability.
Boiler-system efficiency is one of the most documented and published topics for plant engineers and utility managers in commercial and industrial facilities. Understandably, with gas and oil costs at $6 to $10 per million British thermal units of fuel energy value, boiler fuel can represent 30 to 50 ...
It is seen that during start up the chances of low temperature corrosion is high, and hence the need to provide the steam coil air heaters is evident. Both economizer and air pre-heaters are called heat recovery systems in a boiler. Were it not for these heat recovery systems, present day boilers would be operating at much lower efficiency levels.
The start-up of a thermal power plant is a complicated process with many aspects to consider. By conducting it efﬁciently environmental as well as ﬁnancial gains can be achieved. The importance of the start-up schedules of thermal power plants in Germany is increasing as more wind and solar power is being installed in order to
For this purpose, a model of a steam boiler in a power plant taken from literature was implemented in the high-level modeling language Modelica. The optimal control problem of the steam boiler start-up is formulated and solved using the JModelica framework with the Optimica extension.
