Abstract

The utility model relates to a multi-water jacket multi-tube backfire coal-saving stove, belonging to the special equipment which integrates the cooking, the hot water supply, and the heating into a whole. The utility model is composed of a combustion chamber, a reversing chamber, an ash storage chamber, and a discharge flue. The upper part of the combustion chamber is provided with a backfire opening. The inner part of the reversing chamber is uniformly provided with heat exchanger tubes which are connected with an upper and an upper water jackets. After the coal is combusted in the combustion chamber, the fume enters the reversing chamber from the backfire opening, and the fume is discharged from the stove by the discharge flue after carried out the heat exchange by an inner and an outer water jackets, the upper and the lower water jackets, the heat exchanger tubes, and the water jacket of the discharge flue. The utility model has the advantages of coal saving, multifunction, safety, sanitation, etc. The utility model is suitable for the occasion whose heating area is smaller than 700 m <2>.

Description

Multi-tube back-fire coal-saving stove

The utility model relates to the energy-conservation stove of a kind of many water legs multitube reversal-flame type, has and cooks, provides hot water, heating, controllable temperature etc. multi-functional.

At present domestic still do not have an energy-conservation stove of many water legs multitube reversal-flame type, and the effect of coal saving that commercially available energy-conservation stove has is poor, function is few, and what have does not reach 700m ²Heating area.

The purpose of this utility model be to overcome the prior art weak point and provide a kind of energy-conservation, the thermal efficiency is high, the energy-conservation stove of multi-functional many water legs multitube reversal-flame type.

The purpose of this utility model is achieved in that this stove comprises combustion chamber, reversing chamber, ash storage chamber, smokejack.Chamber wall is that water leg is fixed on the upper and lower water leg and communicates in the tubular of garden, and the upper end is a bell, and the lower end is provided with fixed grate and moving grate, establishes a tempering mouth at smokejack opposite direction, interior water leg upside.Reversing chamber is located at outside the interior water leg, surround by upper and lower, inside and outside water leg, in reversing chamber, be provided with the one group of heat-exchange tube that communicates with upper and lower water leg, outer water leg bottom is set up three dedusting temperature control doors separately, ash storage chamber is located at down under the water leg, perisporium is a lamina, in establish one and can take out storage hopper, air can be entered by storage hopper top.Smokejack is made up of the smokejack water leg, and the smokejack water leg is fixed on outer water leg top and communicates, and side is established a dedusting door, and all water legs and heat-exchange tube communicate.

When energy-conservation furnaceman does, air enters combustion chamber (the air inlet is by the control of storage hopper extraction amount) by storage hopper by fire grate, coal fully burns in the combustion chamber and emits heat, part heat is absorbed by interior water leg, another part heat enters reversing chamber with the tempered mouth of flue gas, enter smokejack after suitable its both sides are changeed 180 °, the part heat is absorbed by upper and lower, inside and outside water leg of reversing chamber and heat-exchange tube.Flue gas is when smokejack, and heat is again by smokejack water leg absorption portion heat, and few part heat discharges out of the furnace with flue gas, and the smokejack exit gas temperature can hang down and reach 100 ℃ below the degree.

The more commercially available hanging bladder energy-saving stove of the utility model (patented product) energy-conservation 50%, and has functions such as cooking, provide hot water, temperature adjustment, long preservation kindling material, heating, also can be made into the specifications and models that vary in size, maximum heating area 700m according to the different energy-conservation stoves of heating area ²Have easy and simple to handle, the characteristics of safe and sanitary.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the utility model structural representation full section front view

Fig. 2 is for overlooking partial sectional view

Embodiment is described in further detail below in conjunction with (accompanying drawing): referring to Fig. 1, Fig. 2.The utility model is made up of storage hopper (1), moving grate and handle (2) thereof, dedusting temperature control door (3), fixed grate (4), heat-exchange tube (5), tempering mouth (6), combustion chamber (7), reversing chamber (8), bell (9), last water leg (10), smokejack (11), smokejack water leg (12), interior water leg (13), outer water leg (14), following water leg (15), external water pipe joint (16), dedusting door (17).

Combustion chamber (7) and reversing chamber (8) are respectively to be surrounded by inside and outside, upper and lower water leg (13), (14), (10), (15), and a tempering mouth (6) is established with the smokejack relative direction in combustion chamber (7) upper end.One group of along the circumferential direction equally distributed heat-exchange tube (5) that links to each other with upper and lower water leg is arranged in the reversing chamber (8).Combustion chamber (7) bottom is provided with fixed grate (4), and fixed grate (4) is provided with moving grate and handle (2) thereof, in order to the ash that falls, slagging-off work, storage hopper (1) in the body of heater lower end in order to store ash and control intake.Be provided with circumferential 3 dedusting temperature control doors (2) on the water leg outside the body of heater bottom, can in time clear up the interior dust of reversing chamber (8), dedusting door (17) can be cleared up the interior dust of smokejack (11), and external water pipe (16) is used for the connection of heating equipment.The body of heater upper end is provided with bell (9).
