Description
Technical field
The invention belongs to heating of house facility technology field, be specifically related to a kind of accumulation of heat cool in summer and warm in winter ground a heatable brick bed.
Background technology
Heated kang has a long history and dense cultural deposits, is that the northern China working people grasps under the weather conditions of severe cold and one of the life heating mode that uses for a long time the earliest.The heated kang cost is lower and utilize reproducible biomass energy, has certain ecological intension and abundant technical experience, meets sustainable development idea, meets national energy-saving and reduces discharging policy.
Heated kang also claims " a heatable brick bed " or " large a heatable brick bed ", is a kind of high about 600 ㎜～700 ㎜, and about wide about 2m, length can be fixed with room length
BrickThe Architectural Equipment of stone structure.A heatable brick bed is comprised of a heatable brick bed plate and a heatable brick bed wall, in a heatable brick bed wall flue is arranged, and the above is coated with coagulation adobe kang plate, and covering is touched flat above a heatable brick bed plate with earth.Fiery pit hollow forms flue, and warms oneself by flue.Cigarette is discharged outdoor from the heated kang mouth by chimney at last.General a heatable brick bed link to each other with the kitchen range top, for making the indoor air cleaning, kitchen range not with a heatable brick bed at same room with them, utilize the burning bavin of cooking that heated kang is generated heat during heating, so needn't burn separately again a heatable brick bed.
2004 the end of the year whole nation have approximately 6,700 ten thousand to spread heated kang, population in use reaches 1.75 hundred million.Because the northern China country residents is many and dispersion, heating area is large, is difficult to realize central heating; Simultaneously, heated kang can improve indoor thermal environment and reduce commercial energy consumption with any type of biomass energy, can not increase peasant's financial burden.Therefore, from the application characteristic of fuel in China's rural areas structure, rural economy level and heated kang, heated kang will extensively be continued to use within quite long period always.
Existing heated kang divides traditional console mode heated kang, overhead type heated kang (hanging a heatable brick bed) and wall with flues formula heated kang.These three kinds of heated kang have common limitation:
One, the fuel wood consumption is large, waste fuel, and the thermal efficiency all has much room for improvement.
Two, a heatable brick bed body accumulation of heat weak effect, heated kang is intermitting heating, because the intermittent time at night is longer, so morning in severe winter, indoor temperature was very low, even was lower than 5 ℃.
Three, owing to outside air temperature height in summer, or overcast and rainy outdoor air pressure is low, if the hot pressing in chimney and a heatable brick bed body is too small, or in the situation of outdoor contrary wind (wind direction is opposite with flue gas flow direction), when blast is opposite with hot pressing function, can produce the bad burning phenomenon of kitchen range, cause smoke backflow generation room air pollution.
Four, summer is because cooking to the heat supply of a heatable brick bed body, causes indoor temperature too high.Sleep at night on a heatable brick bed face of heating, it is indoor hotter that people can feel, comfortableness is poor.Therefore, summer, the heated kang heating was the problem of conflict with room temperature lowering always.
The low main cause of the thermal efficiency of kitchen range is that biomass fuel can not fully burn and produces a large amount of carbon dusts and CO, CO
2, also have a small amount of SO
2And NO
X, the flue gas that chimney is emerged is more black, illustrates that then biomass fuel combustion is more insufficient, and pernicious gas content is more.Biomass fuel combustion is insufficient following reason:
One, the cooking stove oxygen feeding amount is inadequate.Its ash-falling chamber of tradition cooking stove is at below ground, fire grate is concordant with ground, fuel combustion produces later on hot pressing, oxygen can not enter from ash-falling chamber, therefore the cooking stove air intake almost completely enters from the cooking stove door, and after biomass fuel inserts cooking stove, itself also stopped air intake, thereby burning anoxic and do not reach abundant burning.
Two, a heatable brick bed and kitchen range difference in height are too small, and flow of flue gas has some setbacks.
From hydromechanical angle, owing to flue gas rises in the process that flows, so the more large more favourable flow of flue gas of a heatable brick bed and the kitchen range discrepancy in elevation.But the height of heated kang a heatable brick bed body is suitable to be suitable for, can not be too high can not be too short, too highly be unfavorable for a heatable brick bed and be sitting on the edge of a kang, too shortly be unfavorable for flowing and heat transfer of flue gas, the height of general a heatable brick bed body is roughly 600 ㎜～700 ㎜, and the cooking stove height is generally about 500 ㎜.
The combustion process that biomass fuel combustion produces flame is two classes: i.e. Volatile burning and char combustion, and the former accounts for 10% of burning time, and latter accounts for 90%.Biomass fuel has following Some features in combustion process: 1) density of biomass fuel is little, structure is more open, and volatile matter content is high, and thermal decomposition begins in the time of 250 ℃, very active with regard to having begun in the time of 325 ℃, volatile matter can separate out 80% in the time of 350 ℃.In the combustion process Volatile time shorter, if air supply is improper, organic volatile divides and is not burnt easily and discharge, discharging fume is black, is the goldenrod cigarette when serious.So enough diffused air supplies must be arranged, must there be enough volumes and certain fire that blocks in the combustion chamber, in order to certain combustion space and burning time are arranged.How much the air supply amount also is one of key of efficiency of combustion simultaneously.2) after volatile matter was separated out gradually and burnt down, the residue of fuel was loose coke, and air motion can entrain into a part of carbon granules flue reduces combustion rate.3) volatile matter burns down, and char combustion is subject to ashes parcel and the difficult impact of air penetration, has hindered the burning of coke, causes residual remaining carbon in the ashes.Therefore ash-falling chamber adds forced ventilation and promotes coke fully to burn to improve biomass fuel combustion efficient.
Therefore, when the height of heated kang is higher than more than cooking stove 300 ㎜, the height of ash-falling chamber is greater than 200mm, and it is not only more unobstructed to discharge fume, and intake is large, and fuel produces CO, the H in the volatile matter
2, CH
4, hydrocarbon C
xH
yDeng meeting completing combustion, after volatile matter was separated out gradually and burnt down, the residue of fuel was loose coke, and when the increasing of air feed oxygen-supplying amount, char combustion can be more abundant.
The thermal efficiency of a heatable brick bed is low mainly to be the accumulation of heat weak effect of a heatable brick bed.
Traditional ground a heatable brick bed also named " combustion pond ", is that China's northeast region-by-region is by " heated kang " in traditional residence evolution and next.When being winter approached, the operation principle of combustion pond heating in the combustion pond, sends into fuel by feed inlet and outlet, then firmly with its dense extrusion and be full of the pond body space, fuel is more closely knit, pond body space charge is more, burning time is just longer, and the air in the fuel gap is fewer, and the speed of glowing is also easier to be controlled.Thus, the combustion pond is a kind ofly to be positioned at the underground combustion space of heating building with main body, the residual broken root of plant, stem, leaf and sawdust etc. are for fuel and make fuel be in the anaerobism state that glows, the heat that produces by conduction, radiation and convection type, improves the heating method of indoor temperature through radiating surface.
Angle from the psychological need of the thermal comfort that satisfies the people, ground a heatable brick bed heating thermal comfort more is better than traditional heated kang heating, because high upper low thermal environment better quality under the thermal gradient in room, indoor surface temperature is even, room temperature is from bottom to top successively decreased gradually, gives the cool good feel of pin temperature head; Improve blood circulation, enhance metabolism.Simultaneously, room temperature from bottom to top evenly distributes after the employing floor heating, and cross-ventilation weakens, and moisture loss reduces, and humidity environment is more favourable to human body.In addition, people had a rest at traditional heated kang and fell asleep night, because traditional heated kang a heatable brick bed face bedding bed clothes cause the heat loss through radiation performance of heated kang greatly to reduce, if do not have other thermals source then body of wall and the cold air on ground and the hot-air convection quickening of a heatable brick bed face top on every side, so room temperature descends very fast.And a heatable brick bed heating one large characteristics in ground are under the double action of radiation intensity and temperature the room to be carried out heating, form more rational indoor temperature field distribution and heat radiation effect, and therefore the advantage of a heatable brick bed heating maximum is to save the energy, and energy-conservation amplitude can reach 30%.So when adopting ground a heatable brick bed Heating Design room temperature, room temperature just can satisfy the required effect of heated kang heating than low 2 ℃ of common heated kang heating, this phenomenon is particularly outstanding when nighttime sleep.
At present, existing ground a heatable brick bed is for making things convenient for the people to enter pan feeding and discharging in the combustion pond, and the combustion pond deeply generally more than 1.5m, is strengthened so build combustion pond construction cost; Fire simultaneously the pool area general finite, the firing rate of use is quite large, and will be processed into broken end, so the fuel use cost strengthens; In addition, combustion pond pan feeding and the discharging effort of taking a lot of work, workload is large; In addition, combustion each position, pond such as the heat radiation end face, to advance (going out) material velar plate, flue part sealing effectiveness bad, can make room air pollution, causes anthracemia.
