Embodiment Construction
[0010] As shown in the figure, the coal burns in the combustion chamber composed of the grate bar 7 and the refractory furnace core 6, the slag falls into the slag storage chamber 9, the fan 8 sends air into the slag storage chamber 9, the air enters the combustion chamber to support combustion, and the coal is heated and burned The chamber is gasified to produce a large amount of combustible gases such as methane, carbon monoxide and hydrogen. The air entering through the secondary air inlet 5 can help these combustible gases to burn completely, and the combustion is relatively complete. The heating sheet 3 heats the water in the water storage chamber 12, and finally the waste gas is discharged from the smoke outlet 1, and a small amount of ash remaining in the flue 13 is discharged from the ash outlet 10.
[0011] The water outlet pipe 10 provides hot water, which can be used for drinking or entering the heating channel for heating.

The invention provides a coal secondary combustion furnace which is an improvement on the basis of an original furnace and can effectively solve the problem of insufficient combustion of fuel. The coal secondary combustion furnace comprises a furnace end, a slag storage chamber, an ash outlet and a water tank, wherein, a combustion chamber comprises a furnace bar and a refractory furnace core, a secondary air inlet is formed between the furnace core and an inner heated furnace body, the slag storage chamber is arranged below the furnace bar, an air inlet is formed beside the slag storage chamber, the air inlet is connected with a fan, waste gas after the full combustion of coal is exhausted to the outside of the furnace from a flue which comprises flue heating plates, a water storage chamber comprises the flue heating plates and an outer furnace body, a water inlet is formed at the upper part of the furnace body, and a water outlet pipe is arranged at the front lower part, thereby eliminating the problem that a chimney is needed as long as the furnace exists. The improved combustion furnace can save the coal by 50 percent, improve the thermal efficiency by 50 percent, achieve the purposes of energy conservation and environmental protection. Furthermore, the combustion furnace has the advantages of less investment and rapid onset of action.
Description
technical field [0001] The invention relates to a cooking and heating stove, in particular to a coal secondary combustion furnace. Background technique [0002] In daily life, because most boilers one-sidedly pursue increasing the heat-absorbing area, it is believed that the larger the heat-absorbing area, the more heat conversion can be improved. Most of the thick black smoke is caused by incomplete combustion of coal. Due to incomplete combustion, it not only pollutes the surrounding environment, but also causes a lot of waste of energy. Contents of the invention [0003] The invention provides a coal secondary combustion furnace, which is modified on the basis of the original stove, which can effectively solve the problem that the fuel cannot be fully burned, and save a large amount of energy. [0004] The present invention is achieved in this way: the coal secondary combustion furnace is composed of a furnace head, a slag storage chamber, an ash outlet, and a water ta...
