With the program several system studies have been carried out, such as the impact of CO2 collection in existing power plants like IGCC, PC and NGCC. In the UPSWING project, funded by EC, the integration of municipal waste incineration in existing PC boilers has been carried out.

With SPENCE® the cold end system of power plants can also be analyzed. The influence of changing cooling water conditions has been determined for most of the power plants in the Netherlands.

With SPENCE® detailed tailor-made models of HRSG have been constructed to verify the given guarantee values for HP and LP steam production. In that case the non-homogenous flue gas temperatures between each heat exchanger section will be taken into account.

The basic libraries of SPENCE®have been translated and implemented on the process computer of the 265 MWe IGCC “Prins Willlem Alexander” power plant in Buggenum. They are used for on-line process calculations to control the coal gasification process.

To determine the influence of co-firing of biomass in coal fired power plants very detailed burner models have been developed. With the models the limitations of 5 pulverized coal (PC) fired boilers were investigated considering co-firing of biomass up to 25% on energy basis.

With the program also integrated correction curves can be constructed of complicated units composed with equipment delivered by different manufacturers and only provided with correction curves for the different equipment. This has been done for several Combined Heat and Power (CHP) plants based on gas turbines.

For a combined heat and power plant with desalination of water a special cost allocation model for the products have been developed, using special exergy functions of SPENCE.

For several clients integrated models are made with an interface with DCS systems to predict the performance of the plant based on design and actual ambient conditions.

With the program also integrated correction curves can be constructed of complicated units composed with equipment delivered by different manufacturers and only provided with correction curves for the different equipment. This has been done for several Combined Heat and Power (CHP) plants based on gas turbines.

The program is used for the education of students in the field of energy conversion processes at the universities of Eindhoven and Aachen.
