Have a kiln that uses a Nyle dehumidifier style drier.
It's designed for low heat, slow curing, for lumber. Around 100-120*
I am trying to dry firewood. It works for that, but the load we tried took 3 weeks and $600 of electricity.
If I had a way to heat the kiln to around 200-220*, it'd take about 3 days to dry.
Electric heaters would work, but at .20 kw/hr it's expensive.
Thinking of a diesel fired heater, like a Frost Fighter or a house furnace.
What's your cost per gallon of diesel or fuel oil?this is the type of heater I was thinking of:
Dunno how well it'd work though.
3 GPH x 24 hours = 72 gallons per day x 3 days = 216 gallons of fuel per load.
Looks like marine diesel's $3/gallon there - that'd be ~$650 per load for energy.
1/7th the lead time may justify the expense, but include your energy costs & machine amortization into your cost per load.
