There are 3 kinds of thermal processes known so far, namely
combustion, gasification and pyrolysis. Differences of the three could be
reviewed by the presence of air / oxygen, temperature and the resulting
product. Pyrolysis is a thermal process that oxygen / air is very limited or
even 0 percent or vacuum. While the gasification air / oxygen is controlled to
a certain amount in order to maximize the product gas. While the amount of
combustion air / oxygen is made so that all the excess fuel can burn
completely.
Gasifier that works between pyrolysis and combustion
primarily requires good control over the amount of air intake / oxygen.
Feedstock condition, and the type of gasifier will affect the resulting gas
products. Controlling with computer will give accuracy process that is generated
so that optimal condition can be identified and maintained. This equipment
works on the basis of information from the sensors to get the best air-fuel
ratio. Gasifier Control Unit (GCU) below which is used to control the air-fuel
ratio in the gasifier.
Gasifier that works continuously with the amount of
automation is expected to meet the energy needs in the long term. A gasifier
system is easy to operate and reliable performance is the purpose of
installation of a number of such instrumentation. An integrated and
synchronized system will improve the overall performance of the gasifier.
Following presentation of the commercialization of biomass gasification for
heat and electricity generation.
