Online puzzle Wood-burning stove

A wood -burning stove (or wood burner or log burner in the UK) is a heating appliance capable of burning wood fuel and wood -derived biomass fuel, such as sawdust bricks. Generally the appliance consists of a solid metal (usually cast iron or steel ) closed firebox, often lined by fire brick, and one or more air controls (which can be manually or automatically operated depending upon the stove ). The first wood burning stove was patented in Strasbourg in 1557, two centuries before the Industrial Revolution would make iron an inexpensive and common material, so such stoves were high end consumer items and only gradually spread in use.

The stove is connected by ventilating stove pipe to a suitable flue, which will fill with hot combustion gases once the fuel is ignited. The chimney or flue gases must be hotter than the outside temperature to ensure combustion gases are drawn out of the fire chamber and up the chimney.
