Quick Answer
Advantages of using fuel-efficient coals include increased warmth, reduced fuel consumption, and lower emissions, making them a preferred choice for outdoor cooking and heating.
Choosing the Right Coal
When selecting fuel-efficient coals, look for those with a higher BTU (British Thermal Unit) content, typically above 12,000 BTU per pound. This indicates a higher energy density, allowing for more efficient combustion and longer-lasting fires. Consider coals with a lower ash content, as they burn cleaner and produce less residue.
Lighting the Fire
To maximize the efficiency of fuel-efficient coals, use the fire starter method of “tinder, kindling, and logs.” Start with dry, fluffy tinder, then add kindling sticks to create a small flame. Once the fire is burning well, add larger logs of fuel-efficient coal, arranging them in a crisscross pattern to promote airflow and complete combustion. Aim for a fire temperature of at least 1,000°F (538°C) to achieve optimal burning efficiency.
Tips for Extended Use
To extend the life of your fire and conserve fuel, use a fire grate or reflector to direct heat back into the cooking area. This can increase efficiency by up to 30%. Additionally, consider using a coal-saving technique like the “coal bank” method, where a layer of coals is built up and then covered with ash to preserve heat. This can help maintain a steady, warm fire for several hours with minimal fuel replenishment.
