The pilot ignition diesel engine technology is a highly efficient technology for the generation of combined heat and power from low calorific value gases e. g. of theiron and steel industry. In this context the pilot ignition engine technology has not to be seen in competition with the conventional large-scale power generation technologies like steam turbine plants or combined cycles, but as reasonable addition for local small and medium-size applications clearly below 100 MW electric. Applications for this technology are e. g. the utilization of process gases from cupola furnaces and small blast furnaces. The pilot ignition diesel engine technology offers the opportunity for an efficient and ecologically sustainable use of low calorific value gases at small to medium-size applications in the iron and steel in dustry.The pilot ignition engine technology is a highly efficient technology for the generation of combined heat and power from low calorific gases. Possible applications for this technology are the utilization of the process gases from cupola furnaces and small blast furnaces. The pilot ignition diesel engine technology operated with LCV gas is characterized by a high electric efficiency ofup to 40 % at a pilot ignition ratio of below 10 % ofthe total fuel input. The operation of the pilot ignition diesel engine technology offers the opportunity for an efficient and ecologically sustainable use oflow calorific value gases at small to medium-size-applications in the iron and steel industry.
