Problems solved by technology

[0003] At present, the small boilers used by ordinary families or some small units in our country are more commonly used in the vast rural areas, such as small cast iron stoves, tea stoves, water jacket stoves, etc., and most of them are made of vertical single drum with row The smoke duct, the inside of the drum is the combustion chamber (hearth), and the lower part is equipped with a grate and ash storage chamber (with an air inlet). The structure is relatively simple and easy to manufacture. The volatile matter cannot reach the ignition point quickly and cannot be fully burned to release heat, and is quickly discharged, which can easily lead to high smoke concentration, serious fuel waste, and indoor and outdoor environmenta

Embodiment Construction

[0012] Fill coal at the top of the furnace (14), and the coal is preheated, dried and burned in the combustion chamber of the furnace above the fire grate. If the fire-sealing switch (9) is placed below, the cooking pot can be placed on the top of the furnace (14) for heating, and the upper and lower fire passages (17) in the center have a uniquely designed shell structure, and are connected with the smoke passage ( 1) Connected, when the hot air flow passes, it can not only greatly increase the heat exchange area of ​​the water-cooled wall, but also ensure that the soot flowing through the fire channel can slide down in time to avoid blockage, but smoke will be generated at this time; if the fire-sealing switch (9) Place it above, and close the upper and lower furnace doors (13), and the air volume is controlled by the movable furnace cover. The central horizontal fire channel (17) is connected with the smoke outlet channel (1). Since the hot flame is below the fuel, the fire...

Description

technical field [0001] The invention belongs to civil boiler technology, and mainly relates to a high-low smokeless energy-saving water heater. [0002] The present invention relates to a domestic boiler using solid fuel. Background technique [0003] At present, the small boilers used by ordinary families or some small units in our country are more commonly used in the vast rural areas, such as small cast iron stoves, tea stoves, water jacket stoves, etc., and most of them are made of vertical single drum with row The smoke duct, the inside of the drum is the combustion chamber (hearth), and the lower part is equipped with a grate and ash storage chamber (with an air inlet). The structure is relatively simple and easy to manufacture. The volatile matter cannot reach the ignition point quickly and cannot be fully burned to release heat, and is quickly discharged, which can easily lead to high smoke concentration, serious fuel waste, and indoor and outdoor environmental poll...
