The Producer Gas generated in Gasifiers can be fed to engine-gensets for producing electrical energy. Bur before the gas is fed into the genset it passes through a series of filters. This results in Ultra Clean Gas and thus when we sell a system for power generation, we call the system (gasifiers + accessories) to be in Ultra Clean Gas Mode.
Electricity can be generated using gasifiers either using diesel engine gensets or using suitably modified natural gas engines/ producer gas engines.
