A suitable combustion technology is
produced, for example, by the company
Jaroslav Cankař and son ATMOS. Their
wood burning boilers allow for biomass
combustion and wood gas production.
Gaseous components (wood gas) are
released from the biomass due to high
temperatures. These are further heated
without the access of air in combustion
space and burnt as a gaseous fuel.
A portion of generated heat is used
for additional biomass gasification.
Depending on the quality of the fuel, the
boiler shows a higher efficiency (81–89%)
than traditional combustion (70%) and
produces minimal emissions. The ATMOS
boilers comply with the limits for obtaining
the Environmentally Friendly Product label
and comply with requirements of the Green
for Savings subsidy programme.
