Huge amount of by-products is still considered as waste and is simply disposed, for example by-product gas is usually flared. Political and social pressure to reduce air pollution and national needs for energy security make these waste fuels interesting for near-future power generation. Unfortunately most of these waste fuels, even when liquefied or gasified, have very low quality and can hardly be used in high-efficiency power systems. Among main challenges are low calorific value and composition fluctuation. Additionally very often there is a high content of sulphur, siloxanes, tars, etc., which have to be removed from the fuel. Modern 4-stroke gas engines designed for power generation applications provide very high efficiency, high reliability and availability. Unfortunately, these gas engines require high quality fuel with stable composition. Horus-Energia together with Cracow University of Technology developed a novel gas supply system HE-MUZG that can adapt to current gas quality and change engine settings accordingly.This article will present results from the HE-MUZG system tests on modern 4-stroke spark-ignition gas engine. Tests focus on low quality gas, such as gas with low calorific value, gas with very low methane number and gas with very big variations of calorific value. Test results compared with performance of that engine in the original configuration show huge improvements. Moreover the HE- MUZG system is easy to implement in commercial gensets.

This paper outlines the main details of a technology transfer educational project between the EU and South America. It was sponsored by the CEC, The British Council and GUASCOR. An international network called GEOPHILES was set up to train ten South American individuals selected by the South American partners. The technical subject was power generation with gas fuel from biomass and low calorific value coal. The objective was to create a team of individuals with experience on a relevant discipline, giving each grantholder a different experience. To achieve this the training took place in several European Universities and a Spanish company. The trainees and their host institutions received state of the art training and material. They were also made aware of the advanced wealth creation capabilities within the European Community. The European membership of the consortium included three Universities with important industrial and commercial links and an industrial partner. This gave the programme a valuable practical element. The project was in two phases, firstly the preparation and delivery of the technical material in an intensive two week course. The second phase of the project was the mobility of the grantholders to Europe to carry out a six and a half month project on a subject relevant to the engineering of suitable power systems. In the short term the benefit to the South American community was a small team of experts with an increased awareness of advanced environment friendly power generation systems. In the long term this may result in valuable business opportunities to European industry.

Absorption Technique

Nitric oxide emitted from the exhaust of spark-ignition automotive engines has long been recognized as a contributor to air pollution. A mechanical analog for the spark-ignition engine was designed, instrumented, and tested. Product gas concentrations of nitric oxide were monitored in the analog, using an ultraviolet absorption technique. Nitric oxide concentrations were found to be independent of the rate at which product gases were expanded.
