    • To increases the overall efficienty of a pyrolysis based power plant, it is proposed to operate an internal combustion engine on a liquid fuel such as pyrolysis oil based fuel (8) and, in addition, pyrolysis gas (9) is added to charge air. This allows using otherwise not lost energy contained in the pyrolysis gas. Specifically, a pyrolysis gas supply unit (120, 220) is proposed that is configured for providing pyrolysis gas (9) into a charge air system (161,261) of the internal combustion engine (162, 262). The pyrolysis gas supply unit (120, 220) comprises inter alia a filtering and compressing unit (122, 222) for removing tar from the received pyrolysis gas (9) and pressurizing the pyrolysis gas (9), a pyrolysis gas regulating unit (124, 224) for regulating a flow of the filtered and compressed pyrolysis gas (9) leaving the pyrolysis gas regulating unit (124, 224), a pyrolysis gas admission valve (140, 240) for controlling the amount of the pyrolysis gas (9) provided to the charge air system (161, 261), and a pyrolysis gas admission unit (142, 242, 342) with a charge air passage (115, 215, 315) that is fluidly connectable to the charge air system (161, 261). The pyrolysis gas admission unit (142, 242, 342) is configured to provide pyrolysis gas (9) into the charge air passage (115, 215, 315).
    • 为了提高基于热解的动力装置的总体效率,提出了在诸如热解油基燃料(8)的液体燃料上操作内燃机,并且另外还加入热解气体(9)以对空气进行充气。 这允许使用不包含在热解气体中的能量损失。 具体地,提出了一种构造成将热解气体(9)提供到内燃机(162,262)的增压空气系统(161,261)中的热解气体供应单元(120,220)。 热解气体供应单元(120,220)尤其包括用于从接收到的热解气体(9)中除去焦油并加压热解气体(9)的过滤和压缩单元(122,222),热解气体调节单元(124) ,224),用于调节离开热解气体调节单元(124,224)的过滤和压缩的热解气体(9)的流动,用于控制热解气体(9)的量的热解气体进入阀(140,240) 提供给增压空气系统(161,261)的热分解气体入口单元(142,242,342),其具有可充气连接到增压空气系统(161,261)的增压空气通道(115,215,315) )。 热解气体进入单元(142,242,342)构造成将热解气体(9)提供到增压空气通道(115,215,315)中。
