摘要
In a method of operating a gas turbine group with low calorific value fuel, the gas turbine group essentially comprises a compressor, a combustion chamber, a turbine and a generator. The low calorific value fuel is compressed by means of a fuel compressor. Low calorific value fuel (11a) in excess of the stoichiometric quantity is mixed into part of the combustion air (9, 9a) during the starting of the gas turbine group so that a stable flame appears. After the attainment of the rated rotational speed (B) and synchronization, at the latest, the quantity of low calorific value fuel (11a) is reduced to such an extent that a ratio is attained which is just over the stoichiometric ratio. The rest of the low calorific value fuel (11b) is mixed into the rest of the combustion airflow (9a, 9b) in order to attain the desired load.
