Abstract

The utility model relates to a hot water stove for cooking and heating which divides into an upper drum and a lower drum. The lower drum comprises a housing, a stove core, a fire grate, an ash box and water returning inlet, and a water jacket is arranged between the housing and the stove core. The lower part of the stove core is provided with a heat resistant layer, and the straight drum part of the upper part is the radiation heating space. The lower drum is connected with the upper drum by a hot fume passage, and the upper drum is provided with a hot water outlet. The interior of the upper drum is provided with a plurality of convection fume exhausting pipes which are communicated with the hot fume passage. The interior of each convection fume exhausting pipe is provided with a spiral slice, and the exterior of the pipes is the water containing space which is communicated with the water jacket of the lower drum. The utility model has high thermal efficiency, good effect of smoke elimination and dust removal, quick ignition and simple structure.

Description

Hot water stove for cooking and heating

The utility model belongs to household solid-fuel furnace, particularly a kind of household solid-fuel furnace with hot water apparatus.

The hot water heating stove of at present existing multiple structure typically has burner hearth and chimney to be with water sleeve type, and fire suppressed type and flue that hearth water sleeve adds the heat convection sheet install around forms such as water jacket outward.Above stove and accessory is because reasons in structure, and it is insufficient to burn mostly, and the fugitive constituent burn-off rate is low in the coal, and carbon black is discharged many, the convection heating surface tar that condenses; Though the fire suppressed type stove and accessory has improved the burn-off rate of coal, convection heating surface is little and make UTILIZATION OF VESIDUAL HEAT IN insufficient, thus the exhaust gas temperature height, and cooking efficient is low, and the backwater inlet is also often too high.

The purpose of this utility model is that design a kind of thermal efficiency height, smoke medicining dust-removing effect are good, quick combustion, the warm dual-purpose hot water heating stove that cooks a meal simple in structure.

Design of the present utility model is such: heating stove divides goes up lower drum two parts, lower drum comprises shell, flue, fire grate, ash-pit and backwater import, between shell and the flue water jacket is arranged, refractory layer is arranged at the flue bottom, the above flue straight drum part of refractory layer is that radiation is subjected to heat space, lower drum connects with upper drum by hot exhaust gases passes, hot water outlet is arranged on the upper drum, there are several convection current smoke exhaust pipes to communicate in the upper drum with hot exhaust gases passes, in the convection current smoke exhaust pipe flight is arranged, around the convection current smoke exhaust pipe is water space capacity, and the water space capacity in the upper drum communicates with the water jacket of lower drum.Convection current smoke exhaust pipe in the upper drum has increased convection heating surface, and convection current smoke exhaust pipe inner screwy fin heating flue gas parallel baffled is half transversal flow turbulent flow, has improved the thermal efficiency; The heat convection face adopts following current to arrange that dilute sulfuric acid dew point corrosion effect has prolonged the stove and accessory life-span when avoiding discontinuous operation; Fugitive constituent burn-off rate in the coal has been improved in the straight barrel type combustion chamber, makes the smoke elimination convective region not have the coal tar phenomenon of condensing.

When the needs cooking time spent, only need the radiation in flue to be subjected to heat space to put movable fire guide sleeve.Ash-removing plate is arranged at the upper drum bottom, when needing the dust under the cleaning convection current smoke exhaust pipe deposition, opens ash-removing plate and gets final product.

Accompanying drawing is a structural representation of the present utility model.

Describe concrete structure of the present utility model and working condition in detail below in conjunction with accompanying drawing.

As shown in the figure, be water jacket (8) between the shell (6) of lower drum (20) and the flue (5), refractory layer (3) and fire grate (2) are arranged at the flue bottom, lay steadily for making stove and accessory, on the ash-pit (1) of lower drum bottom balanced support (16) are arranged.After fuel fully burns in the burner hearth that flame retardant coating (3) are arranged during use, a large amount of heats is conducted to the water in the water jacket (8) by heat space (4) by radiation in the radiation of burner hearth straight drum part, also have the hot flue gas of certain heat to enter the interior convection current smoke exhaust pipe (11) of upper drum (10) from hot exhaust gases passes (17), hot flue gas turns to through the flight (15) in the convection current smoke exhaust pipe (11) and washes away turbulent flow, heat is fully passed to convection current smoke exhaust pipe (11) the interior water of water space capacity (19) on every side, dirt ash in the hot flue gas is washed away and is deposited on the ash-removing plate (9) simultaneously, at any time can remove, the flue gas that fully carries out heat exchange enters flue from upper drum (10) top smoke guiding cover (13) and enters atmosphere.In the time of the heating stove burning, after the water space capacity (19) of the hot water feeding upper drum (10) in the water jacket (8) of lower drum (20) heats again, enter the circulatory system from hot water outlet (12), after the circulation heating, backwater enters water jacket (8) from backwater import (7) and heats.Radiation is subjected to that movable fire guide sleeve (14) is arranged in the heat space (4), is convenient to cooking and uses.Fuel can be added also and can designed coal filling hole (18) adding fuel in the middle part of the stove tube (20) down by upper furnace.

Claims (3)

1, a kind of warm dual-purpose hot water heating stove that cooks a meal, be divided into lower drum (20) and upper drum (10) two parts, lower drum (20) comprises shell (6), flue (5), fire grate (2), ash-pit (1) and backwater import (7), between shell (6) and the flue (5) water jacket (8) is arranged, refractory layer (3) is arranged at flue (5) bottom, the above flue straight drum part of refractory layer (3) is that radiation is subjected to heat space (4), lower drum (20) connects with upper drum (10) by hot exhaust gases passes (17), hot water outlet (12) is arranged on the upper drum (10), it is characterized in that having in the upper drum (10) several convection current smoke exhaust pipes (11) to communicate with hot exhaust gases passes (17), flight (15) is arranged in the convection current smoke exhaust pipe (11), convection current smoke exhaust pipe (11) is water space capacity (19) on every side, and the water space capacity (19) in the upper drum (10) communicates with the water jacket (8) of lower drum (20).

2, heating stove according to claim 1 is characterized in that the radiation in the flue (5) is subjected to heat space (4) that movable fire guide sleeve (14) can be arranged.

3, heating stove according to claim 1 is characterized in that ash-removing plate (9) is arranged at upper drum (10) bottom.
