Description
Technical field
This utility model belongs to internal both boiler technology fields on combustion flame high temperature stove, particularly relates to a kind of housing
The boiler shell that temperature is relatively low, more robust.
Background technology
The high-temperature service normal running temperature that boiler, industrial furnace, combustor (sulphur-furnace, gas generator) etc. are conventional is up to
1000 DEG C-2000 DEG C, and some boiler operatiopn temperature is the highest.These device housings generally use steel construction, reach in temperature
Can reduce rapidly to the intensity of common straightcarbon steel when 400 DEG C, after temperature is higher than 400 DEG C, carbon steel has graphitization to be inclined to, and causes
Material becomes fragile, and therefore generally furnace wall is all to use inside to have one layer or two-layer refractory material steel plate structure, within stoping burner hearth
Portion's heat outwards scatters and disappears, and ensure that the running temperature of box hat is in can be in tolerance range simultaneously.The wall temperature of conventional design body of heater controls
Between 80 DEG C-100 DEG C, owing to investment, structure and material economy consider, the design temperature of some furnace wall is higher than 100 DEG C, very
To reaching 200 DEG C, and some local temperature is higher.
Under above-mentioned hot conditions, the reason manufactured due to change and the equipment of operation operating mode produces a series of asking
Topic.Such as:
1. castable or ramming mass lining can make lining material overtemperature soft because of operation temperature drift reasons such as () maloperations
Change, subside, cause equipment to stop in emergency, even make the problems such as equipment deformation failure owing to temperature is too high；
2. the internal gasification furnace using masonry way need at a certain distance to be provided for absorb the expansion joint expanded and
Passive brick plate.Owing to running for a long time and other reasons, the swelling fiber cotton at expansion joint can tail off and (or lack
Lose), cause equipment wall temperature herein to raise, even up to 400 DEG C.Being in for a long time under this hot conditions, carbon steel there will be
Graphitization phenomenon, material becomes fragile.Brick plate is arranged on adjacent dilatation joint top, owing to bearing refractory brick action of gravity, brick plate
Neighbouring high-temperature kiln wall there will be crackle, causes damage.
3. some refractory material such as high-alumina brick, high alumina ramming mass etc. relatively costly, designing unit or maker are in order to save
About cost, generally selects the fire-resistant heat insulating material that can just tolerate some chemical reaction temperature, or little resistance to of fire-resistant surplus
Fire screen hot material, so the reason such as equipment overtemperature or alignment error can make refractory material deliquescing, and then equipment when maloperation
Material failure.
4. energy loss: device outer surface and air have certain temperature difference, and equipment list area is the biggest, causes quite
A part of heat scatters and disappears, and is unfavorable for energy-conservation.
5. in stove, operation temperature is not easily controlled, it will usually select higher leveled material, uneconomical.
Summary of the invention
The purpose of this utility model is to provide the boiler shell that a kind of case temperature is relatively low, more robust.
Structure of the present utility model is:
The boiler shell that a kind of case temperature is relatively low, including the steel shell body 1 of boiler, is provided with in steel shell body 1
Refractory material 3, it is characterised in that: outside steel shell body 1, it is provided with the spiral coil 2 communicated up and down, the horizontal stroke of this spiral coil 2
Cross section is semicircle or rectangle, and spiral coil 2 is that the rectilinear side contacts outside steel shell body 1 with cross section.
During use, spiral coil 2 adds water or other has the flowing material of cooling effect, in spiral coil 2
Water or other have the flowing material of cooling effect can absorb the heat of steel shell body 1, thus reduce the temperature of steel shell body 1
Degree, makes steel shell body 1 be difficult to by high temperature failure, and case temperature is relatively low, more robust.
Spiral coil 2 outside steel shell body 1 is the helical structure side by side of many spiral coils 2, every helical disk
Pipe 2 has opening respectively in top and bottom.
Every spiral coil 2 is the shortest between the opening of top and bottom, and the high-temperature water in spiral coil 2 the most easily flows out.Many
The helical structure side by side of root spiral coil 2, can make the length of every spiral coil 2 reduce, and high-temperature water the most easily flows out spiral coil
2, prevent high-temperature water length of flow in spiral coil 2 oversize, the problem producing booster.
Advantage of the present utility model:
(1) spiral coil, outside steel shell body adds water or other has a flowing material of cooling effect, water or its
After it has the flowing material of cooling effect to reclaim heat, boiler steel shell body temperature realizes controlled substantially.According to boiler steel
The control requirement of shell body external skin temperatures and thermal loss, can be to use the mode such as thermometer, valve of increasing, adjustable screw coil pipe
Water or other have the flowing material flow of cooling effect, control steel shell body temperature, thus realize the effective control to heat loss
System.
(2), owing to boiler steel shell body temperature realizes controlled substantially, boiler steel shell body therefore can be avoided to surpass
Temperature, carbon steel graphitization becomes fragile and crackle occurs.
(3), spiral coil 2 absorbs water or the steam of heat, may be used for other position techniques of steam generator system
Needs, or outer row is for other use.
Accompanying drawing explanation
Fig. 1 is part section structural representation of the present utility model；
Figure 1 is steel shell body, 2 is spiral coil, 3 is refractory material.
Detailed description of the invention
The boiler shell that embodiment 1, a kind of case temperature are relatively low
Such as Fig. 1, the boiler shell that a kind of case temperature is relatively low, including the steel shell body 1 of boiler, at steel shell body 1
Inside it is provided with refractory material 3, outside steel shell body 1, is provided with the spiral coil 2 communicated up and down, the cross section of this spiral coil 2
For semicircle or rectangle, spiral coil 2 is that the rectilinear side contacts outside steel shell body 1 with cross section.
Spiral coil 2 outside steel shell body 1 is the helical structure side by side of many spiral coils 2, every helical disk
Pipe 2 has opening respectively in top and bottom, and water at low temperature enters spiral coil 2, spiral coil 2 from the lower ending opening of spiral coil 2
Outside steel shell body 1 after spiral, the high-temperature water after being heated by steel shell body 1 is from the upper end open of spiral coil 2
Flow out.Make at a temperature of steel shell body 1, to drop to the non-damageable temperature range of steel.
