Description

Coal-saving stove

Affiliated technical field:

The utility model relates to the coal stove field, particularly a kind of coal-saving stove.

Background technology:

Northern China cold in winter, vast rural area does not have central heating, and most of people use coal stove for heating, cook.Existing coal stove incomplete combustion, waste coal, heat radiation are slowly, ignition temperature is low, environmental pollution is serious, and in addition, existing coal stove can not well burn to second-rate coal.

Summary of the invention:

The purpose of this utility model is to provide a kind of burns fully, saves coal, rapid heat dissipation, temperature height, pollute little coal-saving stove, realizes flame " Clothoid type " burning in burner hearth, can the relatively poor coal of burning quality.

The purpose of this utility model is achieved in that a kind of metal coal-saving stove, comprise: flue, upper furnace body, stone or metal plate for standing a stove on as a precaution against fire, burner hearth, fire bars, stove seat, fire door, bell, its technology of economizing on coal is the form of burner hearth, last 2/3 section of inboard wall of burner hearth is that arc, following 1/3 section are approximate straight tubular, the diameter proportion of the suitable for reading and end opening of burner hearth between 1: 1.3～1.7, the optimum diameter ratio be 1: 1.45 (that is: the burner hearth back cut diameter is 1 o'clock, the burner hearth lower port diameter between 1.3～1.7, optimum diameter is 1.45).The burner hearth upper end is a upper furnace body, and upper furnace body is provided with flue, and the burner hearth below is fire bars, stove seat, on the stove seat fire door is arranged.

Feature of the present utility model is: according to the size of furnace diameter, the burner hearth upper end exceeds 1～5 centimetre near an end of flue than the end away from flue, one section of exceeding of flue end is a firestopping ring, and firestopping ring is the part of burner hearth, and that sees burner hearth from the side suitable for readingly is angle.

Feature of the present utility model is: stone or metal plate for standing a stove on as a precaution against fire can be square or circular.

Advantage of the present utility model is: burns fully, saves coal, temperature height, rapid heat dissipation, thermal efficiency height, compare, economize on coal more than 35%, effectively reduce pollution environment through experiment the utility model and common coal stove, and can the relatively poor coal of burning quality.
