Abstract

The utility model discloses a novel coal-saving heating stove which is used for saving energy for heating stoves and provided with a ventilation pipeline (8), an air supply pipeline (10) and an exhausting fan (9). The utility model is characterized in that the utility model is provided with a set of heat conducting pipes (5); hot airflow flows downwards along the inner side of the outer wall of a stove body to make the surrounding temperature of a stove wall rise; then the hot airflow enters an air intake channel (2) to form a heat exchanger (6) together with the air intake channel (2); cold air entering a stove chamber is preheated; then the cold air enters a pedal disk (7) and is exhausted outdoors by a pipeline. The utility model can improve heat utilization rate and cause coal to completely burn to achieve energy-saving effect.

Description

A kind of novel stove and accessory of warming oneself by a fire of economizing on coal

The utility model relates to a kind of stove and accessory of warming oneself by a fire of economizing on coal, and is mainly used in the energy-conservation of stove and accessory.

The stove of warming oneself by a fire of prior art can not economize on coal or effect of coal saving not good, its main cause is: the stove of warming oneself by a fire is a cost to sacrifice heat-insulating property always, reaches the purpose that heats up around the stove and accessory.Therefore, coal burning is insufficient, and the people just can keep stove fire and not put out from also burning more coal.

Task of the present utility model provides a kind of like this stove and accessory of warming oneself by a fire of economizing on coal, and the existing good insulation measure of stove and accessory has the effect that heats up rapidly again on every side; Heat distributes from bottom to top, improves heat utilization efficiency, and cold air enters burner hearth through preheating, and coal is fully burnt; Stove and accessory bottom stance is by the thermal current heat supply, and temperature is constant within the specific limits.

Task of the present utility model realizes with the following method: this stove and accessory has an exhausting system, makes the thermal current that rises to fire door introduce the bottom along stove and accessory outer wall inboard downwards through inlet channel, draws outdoor again from the bottom.So just can overcome the deficiency of the existing stove and accessory of warming oneself by a fire, reach effect of coal saving.

The utility model will be further described below in conjunction with accompanying drawing.

Air enters burner hearth [3] through fire door [1] inlet channel [2], makes the coal combustion in the burner hearth, the thermal current after the burning rise to fire door by furnace access cap [4] lid toward and in can not inlet chamber, the result be taken out to draw by air exhauster [9] and acts on lower edge heat pipe [5] and flow downward.The stove and accessory insulation is good as far as possible, and thermal current heats up rapidly around also making stove and accessory, and the people also can keep stove fire and not put out from as long as burn very little coal like this.Form heat exchanger [6] when thermal current arrives fire door and inlet channel and heat pipe, cold air obtains entering burner hearth after the preheating, makes coal combustion abundant.Thermal current enters step dish [7] for the warm pin of people, and heat is distributed from bottom to top, improves heat utilization efficiency, enters air draft pipe [8] then, is pressed into air supply duct [10] by air exhauster and discharges outdoor.The indoor air draft pipe that is mainly, vertical have a leak, and yet inwardly suction and outside leakage gas not can be lit a fire by the full cut-off door and window can gas poisoning, reaches the effect of indoor rapid intensification.

Because thermal current has lift upwards, air exhauster flows downward the thermal current in the heat pipe, constitutes a pair of contradiction like this.When fire box temperature rose, thermal current lift increased, so air-flow enters reducing rapidly of step dish downwards, and throughput reduces, and offset the part high-temperature gas and enter the heat that the step dish increases, otherwise throughput increases.As long as suitably choose air exhauster, then can make step dish temperature constant between 40--50 ℃.

If desire to make coal burning rapid, can open power down switch [11], make the portion of hot air-flow directly enter air draft pipe, eliminate the effect of the restriction coal burning speed of thermostatic effect generation.

The utility model is simple in structure, and the energy-saving and pollution-proof effect is remarkable, is suitable for each stove and accessory factory and handicraft workshop production.
