Abstract
Combined heat and power production has high priority in Danish energy planning. Interest has increased for establishing decentralised gas fired co-generation plants based on gas engines or turbines. Approximately 60 gas engines and 10 gas turbines have been installed. These numbers are expected to increase significantly. Most units have been placed at district heating plants or for the supply of blocks of flats. There is great technical potential for co-generation in industry. This market is waiting for shorter pay back time. Today 10 gas turbine co-generation plants are operational with a mechanical rating from 600 kW to 17 MW. There have been problems with condensation of ventilation air on the generator and ice at the air inlet. Short time heat storage facilities insulated hot water tanks are installed in 6 of the plants. Danish plants can expect a reliability from 90-95%. The annual electricity production efficiency is in the range of 21-30% for the simple cycle plants, total fuel utilisation is from 80 to 97%. New plants must, meet a maximum emission of 200 mg/MJ CO for CO and NO{sub x} at full load. NO{sub x} is calculated as NO{sub 2}. The emission of carbon monoxide and unburned hydrocarbons from
