Operating A Gasification Furnace Requires - Heatmaster G Series Operation And Maintenance Manual

OPERATING A GASIFICATION FURNACE
REQUIRES:
1. Use seasoned wood: It is always recommended to
use dry seasoned wood (15-25% moisture, seasoned
1-2 years) when operating a gasification furnace with a
minimal mix of green wood. If required to burn green
or wet wood, always mix with a higher ratio of dry or
seasoned wood .
2. Stacking: Using the illustration to the right, first stack
your primary wood on the coal bed in the firebox so
that as the wood gasifies and burns, the wood above
it falls on top of the coal bed at the bottom of the
firebox to continue the gasification process. Stack your
secondary wood around the primary wood to fill the
firebox, if necessary.
3. Log Sizing: For ideal operation, log sizing should not
exceed 8" in diameter . Exceeding the recommended
sizing may result in doming (which only allows for
the bottom and/or inside core of the log to burn) or
bridging (the wood "hangs up" in the firebox and
separates from the coal bed). Pieces of wood larger
than 8" should be split into smaller size pieces for use
in gasification furnaces.
Improper wood sizing, stacking or excessive moisture
content in the wood may result in the fire going out,
improper burning, and extensive creosote buildup not
allowing for efficient burning of the wood and eventual
furnace malfunction .
