5.2 The construction of a ferrocement gasifier

A typical working schedule is the following:

First week

Final check of available materials and tools, completion.

Wiring of inner cylinders, top attachments, ash ports, covers. Ordering of metal parts, to be prepared in the workshop (fuel bunker, grid, shroud). Preparation and leveling of the platform for the gasifier.

Second week

Plastering of inner cylinders and attachments. Wiring of outer tank, plastering of outer tank. Construction of refractory cylinder and refractory disc. Curing of plastered parts. Begin of assembly of the inner cylinders in the cooling tank.

Third week

Completion of final assembly, water leak proofing.

Installation of the grate and the metal shroud Installation of the engine with gas-air-mixer and gas inlet manifold adapter.

First tests of gas production, run by an electric fan.

Installation of fabric filter bags, first test runs with engine suction.

Last modifications on the gasifier-engine-genset.

Fourth week

Commissioning of the gasifier-engine-genset. Test runs with engine without load.

Demonstration of alternative starting procedures:

- by suction fan
- by suction manifold from engine
- by stove mode

Demonstration to personnel in optimum operation and maintenance of the ferrocement gasifer.
