The winter in Wuhan is very cold. In the era when there is no air conditioner and heater, a coal-burning stove will be set up at home. The stove is iron and the body is black. The whole stove is cylindrical, the lower part is slightly thicker, the four feet are a whole that extends directly from the barrel, and the four feet are thick circular iron pieces, 3, 4 mm thick, 3, 4 cm high. Below the front of the stove is a square-opened furnace door that is used to smash the ash. The upper part of the stove is convex toward the back, flush with the furnace surface but has a raised circle for fixing the chimney, and the middle of the circle is empty to the furnace. The chimney is usually a cylinder made of white iron, which is about the same thickness as an adult's arm. It is divided into three sections. The two straight sections are joined together by a right-angled connection. The lower part of the chimney is connected to the stove, and the horizontal part is from the wall or The opening in the window sticks out. The furnace chamber is divided into two layers. The upper layer is a cavity slightly higher than the three honeycomb coals. A thick iron cover with a small hole in the middle is placed on the top, and only the tongs can be used. (A kind of iron tool like a large scissors, scissors 仞Part is very long, but there is no 仞) pick and place. The upper part of the furnace chamber is connected to the rear of the furnace by a rear opening, and finally communicates with the chimney. This part should be passed through the tongs to prevent it from being blocked by the chimney ash. The upper and lower parts of the furnace chamber are separated by some equidistantly placed iron rods, so that the coal ash falling off the honeycomb coal can fall below and exit from the furnace door.
