Smoking with wet wood The frequently practiced smoking with wet wood causes a significant loss of energy not only from the necessity to evaporate the moisture in the furnace and discharge the steam to the chimney, but also as a result of reduced efficiency of the boiler or fireplace. Condensation […]
Wood burning process For proper combustion it is necessary to meet the conditions of good mixing of fuel with air and appropriate temperature in the furnace not lower than 600 ° C. It is easiest to burn gas, because mixing gas with air is not a problem […]
