Structure (detailed drawing) of type I coal stove

The simplest coal stove is brick, square column, connected by chimneys, which shoot smoke out. The common iron-coal furnace, cylindrical or gourd-shaped, consists of two parts: the bottom and the furnace body. The furnace body is hollow, used for loading coal, with an air door in front and a flue connected to the chimney at the back.

According to the different uses of coal and its products, coal stoves are divided into ordinary coal stoves, shaped coal stoves, shaped coal stoves and honeycomb coal stoves. Ordinary coal stoves directly use briquettes as fuel, while briquette stoves burn briquettes made of pulverized coal. Coal cakes are made of cake-like coal with small holes. The structure of honeycomb coal stove is slightly different from ordinary coal stove because it uses honeycomb coal. The front door can be opened and closed to keep the coal fire from going out.

According to different structures and functions, it can be divided into several types:

Water heating furnace: an inner container is added to the furnace to form a water circulation system inside and outside the fire for heating.

Energy-saving coal stove: the stove bottom is made of clay, with an air inlet in the middle, a convex edge slightly smaller than the diameter of honeycomb coal around the air inlet, and the outer diameters of the boiling water tank and the cooking furnace body are consistent with the stove bottom.

Extended data

When installing the stove, check whether the stove is in good condition. If there are problems such as damage, corrosion and cracks, replace and repair them in time.

Before installing the cooker, try using waste paper at the smoke crossing to see if the flue is unobstructed and there is no smoke crosstalk. The chimney joint should be firmly connected along the stubble, with the thick end facing the coal stove to prevent air leakage, and check whether the flue is unblocked and blocked. If residents seal the coal stove tightly, it will also lead to insufficient coal combustion and produce a lot of carbon monoxide gas.

In case of strong wind, thick smoke, chimney blocked by soot or other things, etc. Gas poisoning can also occur if the gas cannot be discharged or the exhaust volume is small and most of it spreads indoors.

When installing chimneys, citizens should first pay attention to the wind direction to prevent the chimney mouth from facing the tuyere. If the chimney is installed on the south side of the house, the north wind turns to the south wind, which will cause gas backflow. Before starting the stove, check whether the flue is blocked by foreign objects, and often dig out the soot in the chimney. Be sure to check whether the fire is sealed, whether the cover is tight and whether the air door is open before going to bed. If you want to pile up coal, don't press too much coal to prevent flue blockage and poisoning.

The coal stove must be equipped with an air bucket to ensure indoor ventilation without lowering the temperature.

Don't close the doors and windows too tightly. You can stick a "wind bucket" or leave a ventilation hole in the window. The heating stove used during the day is best moved outside at night. When heating with charcoal fire basin, briquette stove or honeycomb coal stove, be sure to light it outside, wait until the fire is strong, and then move outside before going to bed at night.
