This paper investigates whether coal-fired Integrated Gasification Combined-Cycle (IGCC) power plants can be an economically viable future technology for providing less carbon-intensive electricity and heat energy in Germany than today. In the context of CO2 emission mitigation in power generation, energy conversion technologies enabling the implementation of Carbon Capture and Storage (CCS) need...
Na-, K-, Cl, and S-species are of concern due to their relation to problems of corrosion and fouling in IGCC power systems. The aim of this work was to get more information on the influence of temperature on the release of Na-, K-, S-, and Cl-species. Therefore, lab-scale gasification experiments with four different lignites at 1100°C, 1400°C, and 1700°C were carried out. The hot gas was analysed...
The aim of limiting the amount of CO2 that is released together with other exhaust gases from power plants can be reached by technologies allowing for a systematic separation of this greenhouse gas. One such technology is the integrated gasification combined cycle power plant which makes use of a coal gasification step. For the gasification involving temperatures far higher than in typical pulverised...
A new method based on the Young–Laplace equation for measuring contact angles and surface tensions is presented. In this approach, a first-order perturbation technique helps to analytically solve the Young–Laplace equation according to photographic images of axisymmetric sessile drops. When appropriate, the calculated drop contour is extended by mirror symmetry so that reflection of the drop into...
