Ask the Feng Shui master to choose the commencement date and construction site, and ask the skilled mason (who has been doing this for many years) to open the flue and build the chimney. Mark the ground to determine the position, and mark the wall to determine the height. Excavation of smoke exhaust pipes in the wall. Build a chimney outside the house. Then the furnace body is built with ordinary refractory bricks, as well as the furnace door, shovel mouth and furnace cavity.
The furnace chamber is built with refractory bricks, and the space between the furnace body and the furnace chamber is filled with broken sand and gravel. Then fire-resistant construction is carried out on the furnace surface of the furnace cavity, crushed sand and brick sand used in the furnace cavity are padded with materials such as heat preservation for protection, refractory mud is compacted above the furnace cavity with a pot, the refractory mud is smoothed and polished, and then the pot mouth is made. Heat preservation materials and refractory mud have been put away before construction.
There are also certain forces inside the earthen stove, such as the width and size of the grate, the height of the fire retaining wall behind it and the distance from the smoke outlet. If it is not good, the earthen stove will not burn well, either the smoke is not clean or the fire is too big, and the front of the pot will burn unevenly.
Pan Zao! There we call it a "branch pot". The country personally supported the pot several times 30 years ago. Mud paste, red brick, the country has done. If you don't pay attention to these things, it will be easy to burn wood and cook directly. You don't need bricks, you can make them out of mud. Of course, clay stoves and pots are not clean and hygienic. They are all used by the older generation. Now they are all made of red bricks with ceramic tile covers, which are clean and hygienic.
Wood inlet, air inlet and ash chute. The air inlet of the stove is set in the windward direction of the kitchen hall, and the wind is naturally sent into the kitchen hall. Between the edge of the chute and the mouth of the kitchen hall, the width of the kitchen table is 30 cm, and the excavation depth from this point is 55 cm, which is the same as the bottom of the kitchen hall. Air inlet length and width 1m, oven door width 20cm, wood inlet width x height = 10x 10cm, air inlet 10x 15cm. The channel along the slope is trumpet-shaped, and the excavation width to the ground intersection is 60 cm.
