18. LIFESPAN AND MAINTENANCE
The gas producer design life is at least 20 years for all
major fixed gas producer components,
when the outside hearth containment as well as the fuel
compartment are made from 3CR12
steel, but probably much longer provided that it is operated
in accordance with the Operator’s
Instructions. However, seals and gaskets to lids
have to be changed occasionally, while the
electric gas igniters and the condensates screen
need to be cleaned as and when required.
The internal bottom of the condensates collector pocket must
also be cleaned when saturated. This
can be done without stopping the engine. Re-painting should
be done where and when
required. The particle interference sieved sawdust filter
media needs to be changed regularly,
at intervals based on allowable specified vacuum readings,
while the safety
filter cartridge combination must be changed at recommended intervals.
The System Johansson Gas Producers will also function well
in a tropical maritime
environment as well as in cold winter climates. In the
latter case, it will be necessary to
insulate the filters with high heat insulation, light weight
water proof covers. In very cold
climates these can also be provided with electric blanket
heating underneath the outside
insulation, or with heating from the systems waste heat.
The Johansson Wood Gasification System provides a safe
working environment for Operators
and the Vicinity, as long as the Operator’s and Safety
Instructions are followed. Provisions
have also been made to eliminate any foreseeable risks. The
instructions and recommendations in the K G Johansson paper
titled "Producer Gas Poisoning And
Emergency Treatment", which will be issued to all buyers of
gas producers, must be read and followed on all gas producer
sites. |
