|Low Cost Charcoal Gasifiers for Rural Energy Supply (GTZ, 1994, 49 p.)|
|5. Lowering plant costs by ferrocement construction|
A typical working schedule is the following:
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.
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.
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.
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.
