Description

Coal saving furnace

Technical field:

The utility model relates to the field of coal furnaces, in particular to a coal-saving furnace.

Background technique:

The winter in northern my country is cold, and there is no central heating in the vast rural areas. Most people use coal stoves for heating and cooking. The existing coal furnaces have incomplete combustion, waste coal, slow heat dissipation, low combustion temperature, and serious environmental pollution. In addition, the existing coal furnaces cannot burn poor quality coal well.

Invention content:

The purpose of the utility model is to provide a coal-saving furnace with complete combustion, coal saving, fast heat dissipation, high temperature and low pollution, which can realize "revolving" combustion of the flame in the furnace, and can burn poor quality coal.

The purpose of this utility model is achieved as follows: a metal coal-saving furnace, including: flue, upper furnace body, furnace pan, furnace, furnace bar, furnace seat, furnace door, furnace cover, and its coal-saving technology lies in the furnace Shape, the upper 2/3 section of the inner wall of the furnace is arc-shaped, and the lower 1/3 section is approximately straight cylindrical. The diameter ratio of the upper and lower openings of the furnace is between 1:1.3 and 1.7, and the optimal diameter ratio is 1:1.45 (That is: when the diameter of the upper opening of the furnace is 1, the diameter of the lower opening of the furnace is between 1.3 and 1.7, and the optimum diameter is 1.45). The upper end of the hearth is the upper furnace body, and the upper furnace body is provided with a flue, and the bottom of the hearth is a furnace rod and a furnace seat, and a furnace door is arranged on the furnace seat.

The utility model is characterized in that: according to the diameter of the furnace, the end of the upper end of the furnace close to the flue is 1-5 cm higher than the end far away from the flue, and the section above the end of the flue is a fire retaining ring, which is the hearth. One part, the upper mouth of the furnace is oblique when viewed from the side.

The utility model is characterized in that: the stove pan can be square or circular.

The utility model has the advantages of complete combustion, coal saving, high temperature, fast heat dissipation, and high thermal efficiency. Compared with ordinary coal furnaces, the utility model can save coal by more than 35%, effectively reducing environmental pollution, and improving the quality of combustion. poor coal.

Below in conjunction with accompanying drawing, the utility model is further described:

A metal coal-saving furnace, comprising: a flue (1), a furnace cover (2), an upper furnace body (5), a furnace plate (4), a furnace (6), a furnace bar (7), and a furnace base (9) , Furnace door (8), its coal-saving technology lies in the shape of the furnace (6), the upper 2/3 section of the inner wall of the furnace (6) is arc-shaped, the lower 1/3 section is approximately straight cylindrical, and the upper opening of the furnace (6) The diameter ratio to the lower opening is between 1:1.3～1.7, and the optimum diameter ratio is 1:1.45 (that is, when the diameter of the upper opening of the furnace (6) is 1, the diameter of the lower opening of the furnace (6) is between 1.3 and 1.7 , The best diameter is 1.45). The upper end of the hearth (6) is an upper furnace body (5), and a flue (1) is arranged on the upper furnace body (5). Below the hearth (6) are a furnace bar (7), a furnace base (9), and a furnace base (9) Furnace door (8) is arranged on, and furnace lid (2) covers on the stove pan (4).

The utility model is characterized in that: according to the size of the diameter of the furnace (6), the end of the upper end of the furnace (6) close to the flue (1) is 1-5 cm higher than the end far away from the flue (1), and the flue (1) One section that the end is higher is the fire retaining ring (3), and the fire retaining ring (3) is a part of the furnace (6), and the upper mouth of the furnace (6) is oblique when viewed from the side.

The utility model is characterized in that: the stove pan (4) can be square or circular.
