Description

Coal stove for heating

A kind of air-breathing coal stove belongs to the human lives and needs class.

Current people coal commonly used is done the fuel heating, and the warm vapour stove of Natural Circulation is more popular, and it is provided with water jacket in the periphery of burner hearth, make the thermal energy conduction of coal water burning cause water jacket and pipeline diffusion cause indoor, for heating.Because water capacity is many in the stove, the consumption fuel temperature difference excessive and extreme misery is out of proportion greatly again, directly influences the burning of coal fire, even coal is just flame-out when all not firing ash to the greatest extent, and is attached to heat-insulation layer on the burner hearth steel plate also owing to cold and hot irregular coming off.

The utility model rationally adjust fire and hydro-thermal can conduction, make the water capacity in the water jacket adapt to the coal fire heat-transfer rate, reboot air and help heat, accomplish coal hot water heating to the greatest extent, made full use of the temperature of coal, cigarette, vapour, to reach warming, purpose of energy saving.

Structure of the present utility model (seeing Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5) is made up of chimney, water jacket and body of heater, and its principal character is as follows:

One, chimney is that annular flue gas pipe (2) and perpendicular smoke pipe (12) are connected as a single entity, and annular flue gas pipe (2) takes a round around return duct (10).Place, exit, perpendicular smoke pipe (12) upper end, following termination soot blower is provided with chock plug switch (18) at the ash disposal mouth, and these pipeline peripheries are wrapped in by water jacket (1), (16), and, also do not have water jacket communicating pipe (17) near the pipe lower end in water jacket (16) lining of perpendicular smoke pipe.The water of water jacket (1), (16) lining is supplied by water heating device (4).

Two, on body of heater divides, in, three partly down, bell (3) is arranged at top, drip pan (23), return duct (10) and air intake circle (19), below arch bell (3), adorning drip pan (23), this dish is done to reticulate and is placed on the return duct (10), the return duct (see figure 4) is with outward has air intake circle (19) below the water jacket (1), on the taper frid, be provided with the pinkeye (25) that varies in size again, to regulate firepower, make flame circuitous, air intake circle (19) (see figure 3) shape is the garden ring, settle the tube head of air hose (5) in the ring, combustion-supporting as a means of oxygen supply; The peripheral filling of burner hearth (7) perlite in the body of heater of middle part is made heat-insulation layer (11), water heating device (4) (see figure 2) that this layer peripheral hardware useful metal pipe fitting is made its up and down the termination be the garden ring, the centre is linked to be by many standpipes, be located between air hose (5) and the heat-insulation layer (11), water is injected by water inlet pipe (20), emits from the outlet pipe (21) of perpendicular smoke pipe after water jacket (1), (16) circulation.Air hose (5) then is fixed in individually on the internal protecting wall (6) with several metal tubes, and tail end passes to air inlet place of fire grate (9), and head end passes to air intake (19); The bottom is that the furnace bottom air enters and remove the cinder place, by manual snap switch (24), dirt-excluding bucket (14) and bucket rail (15) are formed, manually snap switch (24) (see figure 5) is placed under the fire grate (9), two other handles are located at outside the furnace wall, and the inserted link formed by spring (24) of dress Second Mate shake hands (22), operation handle (22) cinder is promptly fallen into dirt-excluding bucket (14), and suitable bucket rail (15) passes to the body of heater outside, its dirt-excluding bucket is again the fire door that the control air enters, on the shop front of bucket, be provided with gauge tap (8) several eyes are promptly arranged, advance the stove amount with the control air, also can make the usefulness of banking up a fire.
