TimberForge Kiln V1 · TFK-1

Green lumber in.
Premium hardwood out.

A biomass-fired forced-convection drying kiln fuelled entirely by waste heat from the TFR-1 gasifier and Antminer exhaust. Zero fuel cost. 30-day drying cycle. The system that turns raw timber into $2.40/bf export-grade hardwood.

How It Works

Waste heat in.
Premium timber out.

The TFK-1 closes the energy loop. Heat that would otherwise vent from the TFR-1 gasifier and the S19 Pro miner array is captured and forced through a sealed drying chamber — converting green Guyanese hardwood into export-grade kiln-dried lumber at zero fuel cost.

01 · Loading
Green Timber Stickered & Loaded
Fresh-sawn hardwood is stickered with 1" spacers for airflow and loaded onto kiln carts. Initial moisture content (MC) typically 60–100% for Guyanese species like Greenheart and Purpleheart.
Input: green_timber · MC ~80% · 5,000 bf / charge
02 · Heat Source
TFR-1 Exhaust + Miner Waste Heat
The gasifier engine exhaust and miner heat exchangers feed a plenum manifold running the full length of the kiln. Combined thermal output: ~8–12 kW continuous — more than enough to maintain drying temperatures.
Source: TFR-1_exhaust + S19Pro_heat · $0.00
03 · Forced Convection
Variable-Speed Fans Circulate Hot Air
Three low-power EC fans reverse direction on a timed schedule, ensuring even drying across the full stack. Air velocity through the sticker pack maintained at 200–400 FPM for hardwoods.
Fans: 3× EC · reversing · 200–400 FPM
04 · Humidity Control
Venting Manages Drying Rate & Casehardening
Motorised roof vents and humidity sensors regulate the drying schedule. Rapid drying causes checking and casehardening — the KDC-1 controller modulates vents and fan speed to stay within species-safe EMC targets.
Control: KDC-1 · vent_duty + fan_speed modulation
05 · Moisture Monitoring
In-Stack Resistance Probes + Hand Checks
Permanently installed resistance-type moisture pins log MC at top, middle, and bottom of the charge every hour. Target exit MC: 8–12% for most export markets. Equalisation schedule runs the final 72 hours.
Sensors: 6× MC pins · hourly_log · target <12%
06 · Output
Kiln-Dried Hardwood · $2.40/bf Premium
Dried, stress-relieved hardwood is graded, end-sealed, and staged for export. At $2.40/bf vs. ~$0.80/bf green, the kiln effectively triples the revenue per board foot with zero added fuel cost.
Output: KD_hardwood · $2.40/bf · 3× green_value
Technical Specifications

Engineered for
Guyanese hardwoods.

High-density tropical species like Greenheart, Purpleheart, and Mora require precise low-temperature schedules. The TFK-1 is sized and tuned for the species leaving the Bitcoin Timber sawmill.

Flywheel Integration

Where every watt
earns twice.

The TFK-1 is not a standalone system — it is the third output of the TimberForge energy flywheel. The same waste stream that costs nothing to produce creates three separate revenue channels simultaneously.

Heat Source 1
TFR-1 Engine Exhaust
The gasifier engine exhausts at ~400°C. A heat exchanger strips thermal energy from the exhaust stream before it vents, feeding the kiln plenum. Energy that would otherwise be wasted.
Thermal contribution: ~5–7 kW continuous
Heat Source 2
Antminer S19 Pro Waste Heat
Six S19 Pros dissipate ~19.5 kW as heat. Ducted exhaust from the miner enclosure routes directly into the kiln manifold. The miners that mine Bitcoin also dry the lumber — at zero marginal cost.
Thermal contribution: ~3–5 kW usable
Revenue Multiplier
3× Revenue Per Board Foot
Green Guyanese hardwood sells at ~$0.80/bf. The same board, kiln-dried to export specification, commands $2.40/bf. The kiln is the single highest-leverage capital item in the entire operation.
Value delta: +$1.60/bf · 100,000 bf/yr = +$160,000
