Evaluation of Small-Scale Gasification for CHP for Wood from Salvage Logging in the Czech Republic

This study focused on small gasification units for combined heat and power generation (CHP) up to 200 kW of electric power, which can use wood from salvage logging, and assessed the current feasibility of running commercially available units in the conditions of the Czech Republic. In total, the tec...

In total, the technical and economic parameters of 21 gasification units from ten major international producers were compiled.
