5.5 Concluding remarks

From the detailed discussion above it will be seen that a number of operational difficulties were encountered. Those problems are easy to solve and have been remedied in second generation installations.

A major problem could result from the slow carbon build-up in the engine's cylinders as a consequence of traces of tar or dust in the gas. Whether this is due to too low engine loads or to a defective glass fibre cloth filter remains to be tested.

The economy of the gasification system in Sri Lanka compares favourably with diesel-electric generating systems of the same size.
