Technical aspects in detail

Depending on the compostion and the amount of CMM (data delivered by a gas prognosis) and the kind of the mine (abandoned or acticve mine) different types of utilisation are possible. An overview of proved and tested utilisation technologies depending on the CH4 - content are shown in the table below:

Technology	CH4 [%]	Status	Products	Remarks
Gas engines	(25) 30 - 100	proved and tested	Power, heat, emission reduction	since 1996 over 100 units in operation
Boilers / Burners	(20) 25 - 100	proved and tested	Heat, emission reduction	since 1980th
Boilers / Burners	(20) 25 - 100	proved and tested	Heat, emission reduction	since 1980th
