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 northern China working people grasps the earliest and one of life heating mode used for a long time under the weather conditions of severe cold.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 ", and be a kind of height about 600 ㎜ ~ 700 ㎜, wide about about 2m, length can be fixed with room length
brickthe Architectural Equipment of stone structure.A heatable brick bed is made up of a heatable brick bed plate and a heatable brick bed wall, has flue in a heatable brick bed wall, is coated with coagulation adobe kang plate above, cover above a heatable brick bed plate touch with earth flat.Fiery pit hollow, is formed flue, and is warmed oneself by flue.Cigarette finally passes through chimney discharge chamber from heated kang mouth.General a heatable brick bed is connected with the kitchen range top, for making indoor air clean, stove not with a heatable brick bed at same room with them, utilize the burning bavin of cooking heated kang to be generated heat, so a heatable brick bed need not be burnt separately again during heating.
2004 the end of the year whole nation about have 6,700 ten thousand paving heated kang, population in use reaches 1.75 hundred million.Due to the many and dispersion of northern China country residents, heating area is large, is difficult to realize central heating; Meanwhile, heated kang can use any type of biomass energy to improve indoor thermal environment and to reduce commercial energy consumption, can not increase the financial burden of peasant.Therefore, from the application characteristic of fuel in China's rural areas structure, rural economy level and heated kang, heated kang extensively will 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, fuel wood consumption is large, and waste fuel, 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, and because the intermittent time at night is longer, therefore morning in severe winter, indoor temperature was very low, even lower than 5 DEG C.
Three, because outside air temperature in summer is high, 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 when outdoor contrary wind (wind direction is contrary with flue gas flow direction), when blast is contrary with hot pressing function, the bad burning phenomenon of stove can be produced, cause smoke backflow generation room air pollution.
Four, summer, because cooking is to the heat supply of a heatable brick bed body, cause indoor temperature too high.Sleep at night on a heatable brick bed face of heating, people can feel that indoor are hotter, and comfortableness is poor.Therefore, heated kang heating in summer and room temperature lowering are the problems of conflict always.
The low main cause of the thermal efficiency of stove is that biomass fuel can not Thorough combustion and produce 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, then illustrate that biomass fuel combustion is more insufficient, pernicious gas content is more.Biomass fuel combustion is insufficient following reason:
One, cooking stove oxygen feeding amount is inadequate.Tradition its ash-falling chamber of cooking stove is at below ground, fire grate is concordant with ground, fuel combustion produces hot pressing later, oxygen can not enter from ash-falling chamber, therefore cooking stove air intake is almost complete enters from cooking stove door, and after biomass fuel inserts cooking stove, itself also block air intake, the anoxic and do not reach Thorough combustion of thus burning.
Two, a heatable brick bed and stove difference in height too small, flow of flue gas has some setbacks.
From hydromechanical angle, because flue gas is rise in the process of flowing, so the more large more favourable flow of flue gas of a heatable brick bed and the stove discrepancy in elevation.But the height of heated kang a heatable brick bed body is suitable to be suitable for, can not too high can not be too short, the too high a heatable brick bed and be sitting on the edge of a kang of being unfavorable for, is too shortly unfavorable for the flowing of flue gas and the transmission of heat, the height of general a heatable brick bed body is roughly 600 ㎜ ~ 700 ㎜, and cooking stove height is generally at about 500 ㎜.
The combustion process that biomass fuel combustion produces flame is Liang Ge class: i.e. Volatile burning and char combustion, the former accounts for 10% of burning time, and latter accounts for 90%.Biomass fuel has following Some features in combustion: 1) density of biomass fuel is little, structure comparison is loose, and volatile matter content is high, and 250 DEG C time, thermal decomposition starts, just started very active 325 DEG C time, when 350 DEG C, volatile matter can separate out 80%.In combustion process, volatile devolatilization time is shorter, if air supply is improper, organic volatile matter is not easily discharged by burning, and discharges fume for black, is goldenrod cigarette time serious.So must there be the supply of enough diffused air, must there be enough volumes combustion chamber and certain block fire, to have certain combustion space and burning time.Simultaneously air quantity delivered number be also one of key of efficiency of combustion.2) after volatile matter is separated out gradually and burnt down, the residue of fuel is loose coke, and a part of carbon granules can be entrained into flue by air motion makes combustion rate reduce.3) volatile matter burns down, and char combustion is subject to the impact that ashes wrap up and air penetration is more difficult, hampers the burning of coke, causes residual remaining carbon in ashes.Therefore ash-falling chamber adds forced ventilation promotion coke Thorough combustion raising biomass fuel combustion efficiency.
Therefore, when the height of heated kang is higher than cooking stove 300 more than ㎜, the height of ash-falling chamber is greater than 200mm, discharges fume not only more unobstructed, and intake is large, and fuel produces CO, H in volatile matter
2, CH
4, hydrocarbon C
xh
yetc. can burn completely, after volatile matter is separated out gradually and burnt down, the residue of fuel is loose coke, and when air feed oxygen-supplying amount strengthens, char combustion can be more abundant.
The accumulation of heat weak effect of the low mainly a heatable brick bed of the thermal efficiency of a heatable brick bed.
Traditional ground a heatable brick bed is also named in " combustion pond ", is that China's northeast region-by-region is developed by " heated kang " in traditional residence and comes.In combustion pond, fuel is sent into by feed inlet and outlet when the operation principle of combustion pond heating is winter approached, then exert oneself its dense extrusion and be full of pond body space, fuel is more closely knit, pond body space charge is more, burning time is longer, and air in fuel gap is fewer, the speed of glowing also more easily is controlled.Thus, combustion pond is that one is 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 anaerobism to glow state, the heat produced by conduction, radiation and convection type, improves the heating method of indoor temperature through radiating surface.
From the angle of psychological need of thermal comfort meeting people, ground a heatable brick bed heating thermal comfort is more 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 a pin temperature cool good feel; Improve blood circulation, enhance metabolism.Meanwhile, after adopting floor heating, room temperature is from bottom to top uniformly distributed, and cross-ventilation weakens, and moisture loss reduces, and humidity environment is more favourable to human body.In addition, people had a rest and fell asleep on traditional heated kang 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, around the cold air on body of wall and ground is accelerated with the hot-air convection above a heatable brick bed face, and therefore room temperature decline comparatively fast.And ground a heatable brick bed heating one large feature carries out heating to room under the double action of radiation intensity and temperature, form more rational indoor temperature field distribution and heat radiation effect, because the advantage that this place a heatable brick bed heating is maximum is the saving energy, energy-conservation amplitude can reach 30%.So when adopting ground a heatable brick bed Heating Design room temperature, the room temperature 2 DEG C effects that just can meet heated kang heating needed for lower than common heated kang heating, this phenomenon is particularly outstanding when nighttime sleep.
At present, existing ground a heatable brick bed enters pan feeding and discharging in combustion pond for convenience of people, and combustion pond is deeply general at more than 1.5m, strengthens so build combustion pond construction cost; Fire pool area general finite, the firing rate of use is quite large, and will be processed into broken end, and therefore fuel use cost strengthens simultaneously; In addition, combustion pond pan feeding and discharging are taken a lot of work effort, and workload is large; In addition, combustion each position, pond as heat sink top surface, to enter (going out) material velar plate, flue portion sealing effectiveness bad, can room air pollution be made, cause anthracemia.
