NOVELTY - The method involves separating aerosol-bound and gaseous components of pyrolysis raw gas (101) by a wet electric filter (120) into pyrolysis oil (102) i.e. fog droplets, and pyrolysis clean gas (103). The oil and the pure gas are introduced into separate inputs of a dual-fuel engine device (110) over different conveyors. The raw gas is cooled at temperature ranging between 10 and 35 degree centigrade before introducing into the filter by a cooling device. The raw gas is produced in a reverse flow gasifier (130). An air/water vapor mixture is guided into a line system of the gasifier.    USE - Method for producing liquid and gaseous fuel from pyrolysis raw gas for lighting a dual-fuel engine device i.e. dual-fuel engine-combined heating and power station.    ADVANTAGE - The pyrolysis oil and the pyrolysis pure gas are introduced into the separate inputs of the dual-fuel engine device over different conveyors, thus achieving location-free provision of a fuel mixture for lighting the engine device based on sufficient amount of overall solid biomasses. The method avoids contaminations of the wet electric filter, thus preventing required hot vapor cleaning of the filter. The pyrolysis raw gas is cooled at temperature ranging between 10 and 35 degree centigrade before introducing into the filter by the cooling device, thus increasing density of the pyrolysis raw gas introduced into the filter and avoiding condensate, which causes damage, from the pyrolysis raw gas in the engine device.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a device for producing liquid and gaseous fuel for lighting a dual-fuel engine-combined heating and power station.
