Cooking with small wood is easy to underestimate when the first dish finishes quickly. The pan comes off, the fire looks healthy, and the remaining fuel seems sufficient. Then the last dish needs a fresh burst of heat, but the best dry pieces have already gone into the stove. On the Hillrein Zhengtu, a small reserve prepared before lighting makes that final cooking stage much less hurried.
This is a meal-planning habit rather than a fixed fuel allowance. Separate some usable dry wood for the final dish, keep it away from the stove's heat, and decide when that dish will need its strongest heat. You can then feed a working fire instead of trying to rebuild one with food waiting.
Cooking with small wood starts with the last pan
Before lighting, look at the menu from the end backward. A quick vegetable stir-fry asks for strong recovery. A soup that is already hot asks for a small, steady supply. Those two endings should not have the same fuel plan.
Prepare dry pieces around 10 cm long that fit the chamber comfortably. Put the final-dish reserve in a separate dry container at a safe distance from heat and sparks. Keep the air intake and your walking route clear. The reserve is outside the stove; it is not a reason to pack extra wood into the first fire.
Divide the job, not just the pile
- Startup: dry kindling and a loose first load, with gaps for air.
- Main cooking: short dry pieces added to match the pan's demand.
- Final dish: a separate supply that remains available when the earlier cooking is finished.
Do not assign an exact number of sticks to a whole dinner. Two pieces of the same length can differ considerably in thickness and weight. Start with enough prepared fuel available, then learn from what remains after a familiar meal. An unused reserve can stay dry for another session.
Get the first fire established without spending the reserve
Light the loose starting load with low to medium fan support. Let the wood catch and the chamber heat up before increasing airflow gradually. Filling a cold chamber tightly to cover the whole meal makes startup harder; the fire needs room to establish itself.
Zhengtu uses fan-forced oxygen and annular oxygen intake to support gasification combustion. Once the chamber is hot, more of the wood gas can burn instead of escaping as visible smoke. Startup and refueling can still produce smoke. Plan this routine for outdoor backyard or open-air cooking and follow local fire rules.
Bring the reserve into use before the final pan needs it
As the earlier dish finishes, check the working fuel through the intended opening without leaning over the stove. If the next dish needs strong heat, add suitable short pieces while the burn is still established, leaving airflow space. Let the fresh wood catch before starting the demanding part of the recipe.
For a wood stove for wok cooking, a fuller working load with about 80% fan is the usual practical high-heat combination. A fuller load is not a tightly packed chamber. Maximum fan is possible, but 100% consumes wood faster and cannot compensate for missing fuel.
If the final job is simmering soup, use a much smaller correction: around 20% fan with one to two short dry pieces is the useful starting pattern. Add only what the pot needs. There is no benefit in burning the remaining reserve simply because dinner is nearly finished.
Use the leftovers to improve tomorrow's plan
After cooking, note whether the reserve covered the final dish and how much stayed unused. Also note whether that dish was a quick stir-fry or a long simmer. That simple record is more useful than treating every minute of a meal as equal.
As a fuel efficient wood stove, Zhengtu can use less than about 1 kg, or 2 jin, of dry wood per hour in suitable steady conditions. That is not a guaranteed allowance for every meal. Dryness, wind, cookware, fan setting, and cooking style all affect consumption.
The Hillrein Zhengtu stove is built around real cooking with manageable short fuel. Keep enough of that fuel ready for the final pan, and the last dish can receive the same attention as the first.
