Specific embodiment

With reference to the accompanying drawings and detailed description this utility model is described in further detail.

This utility model is specifically related to a kind of formed coal stove for improving fire tube arrangement, is mainly used in the efficient combustion of moulded coal Burn.Its structure as shown in Figure 1, specifically includes body of heater and the discharge flue positioned at body of heater side, and burner hearth 5 and storage are provided with body of heater Grey room 1, burner hearth 5 be located at Dust Storage Room 1 top, centre separate by fire grate 2, furnace body outer wall be water jacket layer, discharge flue and Burner hearth 5 is connection, and communicating position is in the exit of burner hearth 5.

This utility model is, on the basis of said structure, discharge flue structure to be improved, and improved structure is attached In Fig. 1, the fire tube of vertical direction arrangement wherein in discharge flue, is provided with, the high-temperature flue gas Jing in body of heater obtained by briquet is changed After heat, Jing fire tubes discharge stove, during discharge, realize to uncombusted impurity in high-temperature flue gas exhaust-heat absorption and flue gas Remove.The structure of wherein fire tube is divided into two kinds, and a kind of is short fire tube 9, wherein short fire tube 9 is near 5 side of burner hearth, short fire tube 9 Lower port is concordant with the fire door 7 of body of heater, and the high-temperature flue gas Jing discharge flues import 12 in burner hearth 5 horizontally enters into short fire tube 9, another It is long fire tube 11 to plant, and long fire tube 11 is substantially flush away from 5 side of burner hearth, lower port and 5 waist of burner hearth of long fire tube 11, burner hearth 5 The reversion downwards of interior high-temperature flue gas Jing discharge flues import 12 into long fire tube 11, long fire tube 11 and short fire tube 9 lower port by The water jacket wall 20 of bending connects, and the upper port of long fire tube 11 and short fire tube 9 is flushed, and the upper end of long fire tube 11 and short fire tube 9 Mouth is fixed on discharge flue inwall by fire banking-up board 18.Water jacket wall 20 and fire banking-up board 18 are the space-closed between fire tube, it is to avoid cigarette Gas is entered, and only allows flue gas by passing through in fire tube.

The structures shape of fire tube two kinds of paths of flow of flue gas, can be seen that two kinds of streams by the curve arrow in accompanying drawing 8 Path is mainly the different stages suitable for stove use.The lower port of short fire tube 9 is concordant with the fire door 7 of body of heater, this The high-temperature flue gas that sample is obtained by briquet in burner hearth 5, enter short fire tube 9 along horizontal direction, directly connect the outer air of stove, cigarette Gas is good by property, is quickly generated negative pressure in burner hearth 5, and so short fire tube 9 promotes air circulation, provides fully for burning in burner hearth 5 Oxygen, this mode is mainly used in that stove is initial to light a fire the stage, or the short time needs the stage of very hot oven, quick height of lighting a fire Effect；The lower port of long fire tube 11 is substantially flush with 5 waist of burner hearth, i.e. the lower port seat of long fire tube 11 will be less than short fire tube 9 Lower port, after high-temperature flue gas need to flow downward, a part still has most by long fire tube 11 by front short fire tube 9 Passage, enters back into long fire tube 11, is formed and forces reversion dedusting, is mainly used in the fuel combustion very hot oven stage, and endothermic effect is good, energy-saving ring Protect.

In order to be collected to the uncombusted dust in fire tube in this utility model, it is flue gas merging chamber in the top of fire tube 19, chimney 10 of 19 upper surface of flue gas merging chamber for necking is Rotary dust collecting chamber 13 below fire tube, and Rotary dust collecting chamber 13 passes through Dogleg passage is connected with discharge flue import 12, is square ash-falling chamber 14, ash-falling chamber 14 and storage ash below Rotary dust collecting chamber 13 Separate between room 1, cleaning door 21 is provided with 14 side wall of ash-falling chamber.

When middle fire tube of the present utility model is processed, for the ease of processing, general fire tube adopts the steel pipe of normal diameter, Length of its long fire tube of design 11 is 2 times of 9 length of short fire tube or so, or according to 5 height of burner hearth need somewhat adjust. Can see in accompanying drawing 2, short fire tube 9 arranges a row, long fire tube 11 arranges two rows, it is 5 often to arrange fire tube number, in long fire tube 11 Middle part be provided with the reinforcement being connected with discharge flue inwall, strengthen the rigidity of fire tube, it is to avoid because vibrations damage fire tube.Accompanying drawing Spacing of the spacing of the 9 distance fire tube 11 of short fire tube in 2 more than two platoon leader's fire tubes 11, this is because fire tube lower port is not in One plane, but lower port needs to connect by water jacket wall 20, and the water jacket wall 20 between long fire tube 11 and short fire tube 9 needs Bending, it is therefore desirable to leave the distance of bending.

Schematic diagram of the accompanying drawing 3 for the secondary air passage 15 in this utility model, with reference to accompanying drawing 1, secondary air passage 15 Positioned at body of heater front side wall, 5 very hot oven layer of burner hearth periphery, secondary wind can be heated, it is to avoid humid air is entered affects burning；Secondary air The secondary air inlet 3 of passage 15 is located at the top of Dust Storage Room 1 and fire grate 2, and secondary air inlet 3 is provided with airflow regulating switch, its knot As shown in Figure 6, adjusting air inlet amount size can adjust intake volume with the main air intake at Dust Storage Room 1, in reality to structure respectively Typically keep main air intake and secondary air in rational ratio in use, realize preferable air distribution effect.Secondary air passage 15 Secondary wind outlet be around the rotation air channel 16 of stockhole, to rotate the fire-collection ring 17 that air channel 16 surrounds 5 exit of burner hearth, rotation It is 17 comprehensive air distribution of fire-collection ring to turn air channel 16, enters second-time burning to the fuel gas of high temperature, improves efficiency of combustion.

Fire-collection ring 17 in this utility model is taper barrel structure, and as shown in Figure 7, its side is provided with the little of inside and outside connection Hole, is provided with gear coal tooth 6 and firestopping ring 8 above fire-collection ring 17, between fire door 7, its structure is shown in attached Figure 4 and 5, gear coal tooth 6 and gear Pyrosphere 8 constitutes an annulus around fire door 7, and wherein firestopping ring 8 is located near discharge flue side.Gear coal tooth 6 includes one Semi-circular shape plate and the pecten set on semicircular plate surface, its projection it is highly-filled in fire door 7 and fire-collection ring 17 it Between.Firestopping ring 8 be semi-circular shape structure, surface arc-shaped transition, which is filled in fire door 7 and between fire-collection ring 17.6 He of gear coal tooth Firestopping ring 8 is placed at fire door, carries out break-in to high-temperature flue gas circulation style so as to which the water jacket layer at fire door is fully contacted, Fully absorb heat in high-temperature flue gas, improve heat utilization efficiency, can simultaneously be effectively to high-temperature flue gas in it is not sufficiently combusted Tiny coal ash is collected, it is to avoid enter air, pollutes surrounding；

As can be seen that 5 top of burner hearth is tapered configuration in accompanying drawing 1 and 8, its outlet is circle, and 5 bottom of burner hearth is side The storage bin of shape, is circular to square transition structure in the middle part of burner hearth 5, defines the stove that circular upper part and square lower part and storing burning are integrated Thorax 5, is fire-proof heat-insulating material between burner hearth 5 and water jacket layer.Fire-assembling style of the chamber structure using integrally formed " circular upper part and square lower part " Burner hearth, its storage bin bottom are spacious, and good permeability is difficult slagging scorification, and in upper-part centralized, poly- fire is heated, and radiant heat is high, dedicated for type Coal combustion, burning condition are sufficient, full combustion of fuel, and the thermal efficiency is high.
