Як отримати до плюс + 25% тепла від дров додатково. Проводимо два експерименти. Вплив режиму горіння

Video about two experiments on burning wood. The same acacia as in previous experiments was used as test samples. 1. Experiment. In one of the previous videos, whether it is necessary to chop firewood, we burned 10 kg of acacia chips and 10 kg of large logs. The result in terms of heat output was almost the same, but the burning time, smoke temperature and temperature in the heating system were very significantly different. To put a final point on this issue, today we will burn 10 kg of mix, 5 kg of group logs and 5 kg of chips and + 1 kg of pine chips for kindling as in previous experiments. Weighed and loaded everything as last time. Cleaned and heated the boiler. The conditions are identical. After burning, I determined that if we burn it in the form of a mix, we will get more than 5% more heat. at the same time, the burning time and other indicators are practically the same. 2. Experiment. I take 10 kg of acacia chips and burn them under the same conditions, but I will not burn all the firewood at once, but I will add a little at a time, ensuring the best burning mode. The burning time was slightly shorter, and there was almost no difference in other indicators, except for the amount of heat received. There was 25% more heat. However, this method of burning requires a lot of time to chop the firewood and burn it in this way, although it allows you to save up to 25% of firewood
