Abstract

The utility model relates to an indoor coal burning heating furnace. The furnace body is provided with a radiation fin and the heat can be transferred directly through the radiation fin to the ambient. At the same time, a furnace chamber which can enable the coal to burn sufficiently, a primary and a subsidiary fume chambers are arranged on the utility model. A fume channel is circuitous and the heat utilization rate is high. The harmful gas is exhausted by a second order and the indoor pollution is little. Except for heating, the indoor coal burning heating furnace can be used for heating water, carrying out heat processing for foods, etc. The utility model has the advantages of novel design and reasonable structure, and is particularly suitable for the household use and the office heating.

Description

Energy-saving anti-pollution heating stove

The utility model belongs to a kind of indoor burning coal warming stove.

Existing indoor burning coal warming stove has 2 main weak points, and the one, the heat insulation packing material between the stove heart and the furnace body wall has stoped heat distributing around body of heater, and most of heat is overflowed from smoke pipe, thereby has influenced the heating of house temperature greatly; The 2nd, burn coal and produce pernicious gas, very easily be dispersed into indoorly, not only be harmful to human body, and inside plant is produced certain corrosiveness.

At the deficiencies in the prior art, the utility model provides a kind of thermal efficiency height, and can effectively prevent the burning coal warming stove of smoke pollution indoor environment.This stove mainly is made up of the body of heater that has fin, the stove heart, stove heart cover, grate, stove heart pressing plate, inner roof brick, inner cover plate, outer bell, outer cover plate, ash bin, manual fire door, elbow smoke pipe and movable air door etc.Be evenly equipped with corrugated fin around the upper of furnace body, simultaneously, have the burner hearth that the space is bigger between the inboard wall of furnace body and the stove heart overlap and between stove heart pressing plate and the inner roof brick, and a main smoke-box and a secondary smoke-box are arranged.

Now in conjunction with the accompanying drawings the structure and the course of work of this utility model is described below:

Fig. 1 is energy-conservation antifouling warming stove front view;

Fig. 2 is along the cutaway view of A-A face among Fig. 1.

Referring to Fig. 1 and Fig. 2, grate (6) places on the inner bottom plating of body of heater (1), grate (6) is gone up and is placed grate plate (5), the stove heart (3) is placed in the hole that grate plate (5) were gone up and placed to grate (6), stove heart cover (4) fastens grate (6) and grate plate (5) outside the stove heart (3), and be fixed on the body of heater (1), put into heat insulation packing material (8) between the stove heart (3) and stove heart cover (4), stove heart pressing plate (7) is fitted on the stove heart (3) and the stove heart cover (4).Inner cover plate (9) Mi Gai is in the upper end of body of heater (1), outer cover plate (12) is sleeved on the upper boss of body of heater (1), it is inboard closely connected with inner roof brick (9), be evenly equipped with through hole (20) along 3/4ths garden weeks of inner roof brick (9) edge, these holes communicate with the upper space of fin (2), along the same same side radially of outer cover plate (12) one a main exhaust smoke hole (23) and a secondary exhaust smoke hole (24) are arranged respectively, and communicate with elbow smoke pipe (16), and the basal area of main exhaust smoke hole (23) is greater than the basal area of secondary smoke exhaust pipe (24).In the Baltimore groove of inner roof brick (10) and inner cover plate (9), all be filled with heat-barrier material (11).Inner roof brick (10) covers on inner cover plate (9), outer bell (13) covers on outer cover plate (12), movable air door (17) is installed in the elbow smoke pipe (16) by pivot pin, elbow smoke pipe (16) is fixed together with outer cover plate (12), ash bin (14) is provided with manual fire door (15), and placing the cavity of body of heater (1) bottom, stove pin (18) is affixed with body of heater (1) lower end.

When honeycomb briquette burnt in the stove heart (3), its flame stretched into burner hearth (19), was pressed towards in the fin (2) on body of heater (1) top after rising to inner roof brick (10), and heat directly transmits outside stove through fin (2).Heat-barrier material (11) can prevent that heat from overflowing from inner roof brick (10).The harmful smoke that coal produced in when burning on the one hand in burner hearth (19) through upper space (25) (see figure 2) of fin (2), enter main smoke-box (21) by the through hole (20) on the inner cover plate (9), and then, discharge outdoor from elbow smoke pipe (16) through the main exhaust smoke hole (23) on the outer cover plate (12); On the other hand, the flue gas that leaks the minim gap between inner roof brick (10) and inner cover plate (9) then enters secondary smoke-box (22), secondary exhaust smoke hole (24) on outer cover plate (12) and main exhaust smoke hole (23) are discharged outdoor by elbow smoke pipe (16) at last.Adjusting activity air door (17) and manual fire door (15) can be controlled furnace temperature; Taking-up inner roof brick (10) can be heated up water and be carried out food hot-working; Extract ash bin (14) out and can remove coal ash.

Use this utility model, coal can be fully burned, heat directly by fin (2) to around distribute, simultaneously, discharge flue is circuitous wanders, thermal loss is less, thereby thermal efficiency height.Harmful smoke is discharged through secondary, and is very little to indoor environmental pollution.In addition, if add the annex of boiler and so on when making, can also preheating cold water, even can also satisfy the requirement that spraying steam improves indoor humidity.

This stove modern design, rational in infrastructure, result of use is good, is particularly suitable for the usefulness of family and office's heating.
