IMPROVEMENTS IN WOOD BURNING EQUIPMENT AND METHODS HAVE RESULTED FROM BETTER FUNDAMENTAL KNOWLEDGE OF HOW WOOD BURNS, TOGETHER WITH DEMANDS FOR BETTER, MORE UNIFORM HEATING WITH GREATER CONVENIENCE AND LOWER COSTS OF OPERATION. Mechanical feeds and automatic controls have been applied to wood-burning furnaces, and special domestic burners for sawdust and hogged fuels have been developed. Suspension burning of dry wood has been applied in industrial furnaces. A special type of furnace has been developed for burning very wet wood and bark, and high-efficiency magazine-type heaters of the slow-combustion type are being used. Fireplaces and charcoal grills have been redesigned for greater efficiency. Three distinct phases in the burning of wood may take place in sequence or simultaneously 1 the removal of free water by evaporation below the boiling point and vaporization above the boiling point 2 the chemical breakdown of wood into charcoal, gas, and volatile liquids occurs and 3 the charcoal is burned forming CO2.
