Abstract

A heating furnace for school use mainly comprises an interlayer water-holding furnace body and a furnace fire hole connected with the upper surface of the interlayer water-holding furnace body. An interlayer water-holding heating body is communicated with the interior of the interlayer water-holding furnace body, and smoke pipes are arranged on the upper side and on the lower side of the interlayer water-holding heating body respectively and are communicated with a turn smoke pipe positioned at the ends of the smoke pipes. The heating furnace provided by the utility model adopts the structure, in which the interlayer water-holding heating body is communicated with the interior of the interlayer water-holding furnace body, and the smoke pipes are communicated with the upper side and the lower side of the interlayer water-holding heating body respectively, so as to increase the heating area to the furnace body interlayer water circulating water. By adopting the heating furnace, the smoke heat generated by the sufficient combustion of fuel in the inner cavity of the furnace body is turned and circulated through the turn smoke pipe positioned at the ends of the smoke pipes, so as to effectively improve the heating efficiency to the furnace body interlayer water circulating water, and greatly reduce fuel consumption and the pollution to the outdoor environmental air.

Description

The Heating stove that school uses

(1) technical field: the utility model relates to Heating stove; Be specifically related to the Heating stove that a kind of school uses.

(2) background technology: do not adopt the school of collective's heating in the prior art, normally adopt the Heating stove of hot water circuit heating, its structure is to be connected to communicate by circular interlayer appearance water body of heater and interlayer appearance water smoke exhaust pipe to constitute.Exist not enough: the one, it is less that described interlayer holds the body of heater and the smoke exhaust pipe inner chamber endotherm area of water, and some directly acts on fire door place above the body of heater pyrotechnics heat of body of heater inner chamber fuel combustion, and is lower to the recirculated water efficiency of heating surface in its intracavity sidewall interlayer; The 2nd, in addition the pyrotechnics heat that is not fully burned of some fuel holds the water smoke exhaust pipe by interlayer and directly enters chimney and discharge outdoorly, has increased the consumption of fuel; The described dense smoke that does not have clean-burning pyrotechnics to form has seriously polluted outdoor surrounding air again.

(3) summary of the invention: at the deficiency that above-mentioned prior art exists, the Heating stove that provides a kind of school to use is provided the purpose of this utility model; Be intended to improve to the efficiency of heating surface of its interlayer recirculated water and reduce fuel consumption and reduce the pollution of outdoor environment air.

For achieving the above object, the technical solution of the utility model is achieved in that the Heating stove that this school uses, and comprises that mainly interlayer holds water body of heater and the stove fire hole that is connected in above it; It is to be communicated with interlayer to hold the water calandria in described interlayer holds the water body of heater; The upper and lower that holds the water calandria at described interlayer is equipped with the revolution flue connection of pyrotechnics pipeline through its end.

The utility model is taked said structure, is communicated with interlayer in the water body of heater and holds the water calandria and be communicated with the pyrotechnics pipeline at the upper and lower that described interlayer holds the water calandria by holding at interlayer, has increased the heating surface (area) (HS to furnace sandwich recirculated water.Realized that fuel is fully burned the pyrotechnics heat that forms through the revolution flue secondary rotary circulation of pyrotechnics pipe end at the body of heater inner chamber, has improved the efficiency of heating surface to furnace sandwich recirculated water effectively; Reduce the consumption of fuel significantly and reduced the pollution of outdoor environment air.

Fig. 1 is the cutaway view of a kind of embodiment of the utility model;

Fig. 2 be among Fig. 1 A-A to partial sectional view;

Fig. 3 be second kind of embodiment of the utility model with reference to A-A among Fig. 1 to partial sectional view;

Fig. 4 be the third embodiment of the utility model with reference to A-A among Fig. 1 to partial sectional view;

Fig. 5 be the 4th kind of embodiment of the utility model with reference to A-A among Fig. 1 to partial sectional view.

(5) specific embodiment: Fig. 1-shown in Figure 5.The Heating stove that this school uses comprises that mainly interlayer holds water body of heater 1 and the stove fire hole 6 that is connected in above it; It is to be communicated with interlayer to hold water calandria 3 in described interlayer holds water body of heater 1; The upper and lower that holds the water calandria at described interlayer is equipped with the revolution flue connection (shown in Figure 1) of pyrotechnics pipeline 4 through its end.For the teachers and students of school heat up water, cook conveniently, corresponding in the stove fire hole 6 that described interlayer holds above being connected with fire-assembling hole 7 on the water calandria 3 and described interlayer holding the water body of heater.Described pyrotechnics pipeline 4 can or be the round tube that spacing arranges by the flat pipe and connect and compose (Fig. 2, shown in Figure 3); Can also be connected with the round tube that is the spacing arrangement by the flat pipe and constitute (Fig. 4, shown in Figure 5).Coal-fired and coal hook, coal shovel are convenient for splendid attire, and the side inner chamber at described interlayer appearance water body of heater 1 is provided with coal storage case 2; Opening part at described coal storage case 2 is provided with chamber door 9.When the teachers and students of school warmed oneself, the pyrotechnics of body of heater inner chamber sufficient combustion was discharged outdoor only to 10 heating of the recirculated water in its interlayer by the secondary rotary circulation via interlayer appearance water smoke exhaust pipe 11 of pyrotechnics pipeline 4.Cover plate on the fire-assembling hole 78 is taken off, and the part pyrotechnics of body of heater inner chamber acts directly on 6 places, stove fire hole by fire-assembling hole, the teachers and students of school desirable warm heat up water, cook dual-purpose (shown in Figure 1).

Claims (3)

1. Heating stove that school uses comprises that mainly interlayer holds water body of heater (1) and is connected in stove fire hole (6) above it; It is characterized in that: in described interlayer holds water body of heater (1), be communicated with interlayer and hold water calandria (3); The upper and lower that holds the water calandria at described interlayer is equipped with the revolution flue connection of pyrotechnics pipeline (4) through its end.

2. the Heating stove of using according to the described school of claim 1 is characterized in that: described interlayer holds that to be connected with fire-assembling hole (7) on the water calandria (3) corresponding with the stove fire hole (6) above the described interlayer appearance water body of heater.
