FIREWOOD SEASONING STUDY

A comparative study of drying time between conventionally sawn and split firewood and sheared and split firewood (Chomper wood).

The chart below shows the differences in the number of days for each species to reach the same dryness (percentage of moisture loss by weight).

SW = Conventionally sawn and split firewood

CW = Sheared and split firewood (Chomper wood)

SPECIES	DRYING DAYS
	CW	SW	CW	SW	CW	SW	CW	SW
Douglas Fir	15	20	30	45	45	105	60	160+
Western Alder	15	30	30	53	45	78	60	150
Western Maple	15	22	30	42	45	60	60	105
Red Oak	15	20	30	48	45	90	60	130
White Oak	15	18	30	52	45	97	60	160+
Black Oak	15	20	30	43	45	110	60	160+
Cherry	15	18	30	36	45	55	60	90
White Birch	15	16	30	33	45	53	60	75
Red Maple	15	17	30	40	45	90	60	120
Average	15	20	30	44	45	82	60	127+

Note: The table above shows conventionally sawn and split firewood processed from nine species of wood took an average of 127 plus days to reach the same dryness (moisture content) that Chomper processed wood achieved in 60 days. Chomper processed wood can be sold as seasoned wood much sooner than conventionally processed wood thereby increasing your profits.

Note: The samples for each species were taken from the same log, two 16" lengths sawn and two 16" lengths sheared. These blocks were then quartered making a total of sixteen pieces for each species. The initial moisture content and characteristics of the sample pieces were the same so test results could be accurately compared.

Tests were performed in 1987-1988 and were sponsored by a grant from the Department of Energy (DOE).
