Implementation of the two-stage gasifier in an energy system

The objective was to investigate the safety conditions of the Viking system and to develop and implement a new operating system for flexible heating and electricity demand. The project improved a number of components, and long-term experiments were conducted covering almost 4,000 operating hours, the majority with engine operation. The system showed reasonable control capabilities. Various wood fuels revealed a difference in the amount of unburnt carbon in the ash (0.1–6% of heat input). The project contributed considerable knowledge related to upgrading the Viking gasifier at Weiss A/S (project 6529).
