[Gasification] Commercial gasifiers in Europe

Hi Tom and list,

Spanner builds units in two sizes; 30 kWe and 45 kWe. I visited Spanner´s

stand at Agritechnika in Hannover last month and they told that they have

sold 240 units. I have seen about 20 of these units during the last years.

Most of them have been running. Thery use a downdraft gasifier with five

nozzles, no constriction and a half fixed half rotating conical "chistmas

tree" grate. The feed sluice for wood chips is massive and robust.

Filtration is dry with a pneumatically operated simple mechanical cleaning

system. The system for sensing fuel levels is robust and clever.

In Finland there is no Spanner unit, but in Latvia there are 23. In

Finland Volter Oy builds rather well functioning 30 kWe woodgas CHP units

with adjustable gasifiers and dry filtration.
