Background technique

Portable outdoor camping stove is most of backpackers, the fan that camps, trekking expedition person and field survivorship hobby The essential items of persons.Current most popular style is propane, butane or alcohol fuel stove.Some in these stoves are tight It gathers and lightweight, but each stove in these stoves is always needed fuel transport to culinary art place.These fuel tanks For go on a hike, camp be for field survivorship it is huge and bulky, for going on a hike, camp with field survivorship and Speech, weight and volume is vital.These fuel tanks interfere user and occupy the his or her time, because of each fuel Tank must be recycled, refills or be abandoned after use.

Bonfire is without using fuel tank, because bonfire is supplied by deadwood, log or the available various biomass searched out To fuel, but many spot campings do not allow to light bonfire.In addition, bonfire provides Carbon balance as biomass furnace Environmental advantage, because the carbon dioxide discharged via the natural decomposition of biomass is and using biomass as fuel combustion It generates.However, burning fuel due to inefficient fuel consumption generates harmful bi-products and hydrocarbon in bonfire or outdoor flame.

When firewood burns in bonfire, flammable wood gas is discharged in the form of volatile organic compounds.These shides This usually contains at least 50% available potential chemical energy source from wooden fuel.Exothermic reaction (combustion of wood) about exists 250 DEG C of beginnings, and wood gas will not be lighted until about 600 DEG C.The burning layout of fireplace or bonfire can not light mostly These gases of number, because they are not typically achieved the sufficient temp of wood gas burning.These unburned fuels are in dispersion It cools down and condenses, and form particle in the form of cigarette.Cigarette is the fuel slatterned.

Firewood stove theing improvement is that on open fire: each stove includes combustion chamber.In firewood stove, combustion chamber Inhibition with the wood gas in fume extractor (if present) is played the role of making gas superheat, and causes " second-time burning ".This Kind second-time burning enables firewood stove to generate more heat than fireplace or the fuel of bonfire per unit mass.Burn it is hotter, Time is longer, and the efficiency of firewood stove is higher.However, being currently available that the Portable wood wood stove tool of most of models does not have usually Have and reaches enough temperature or enough firing durations to consume most of volatile organic compounds, but these stoves It is higher than open fire energy efficiency.

" rocket stove " is because user can listen when stove can generate muffled sound at high operating temperatures named in this way To the sound of similar " rocket " transmitting, " rocket stove " becomes popular biomass furnace in decades recently, is loved wood The welcome of the user and field survivorship fan of wood stove.Compared to many other firewood stoves, the design of rocket furnace is provided to life The consumable more effective utilization of substance.The concept of rocket stove is related to, and air flows through produced by the high temperature in combustion chamber Partial vacuum towards combustion chamber attract (traction) (this relationship usually pass through Charles' law and Boyle law combination or Perfect gas law quantitatively describes, different people, different views).

The design of rocket stove conventionally used " L-type ", so that fuel and air are directed in combustion chamber.Air via " corner " water of fuel and air shooting device (fuel and air shooting device are commonly referred to as wooden case or fire-box) direction " L-type " Level land guidance.Guidance of the air in fuel and air shooting device is before combustion in air close to following combustion chamber and packet Preheated air when enclosing fuel, the convection current to reduce combustion chamber is cooling, and convection current is cooling usually empty by the environment inside combustion chamber The uncontrolled interaction of gas and occur.The characteristics of rocket stove designs usually combustion chamber is heat-insulated and (more common) Fume extractor is heat-insulated, to prevent the air for accommodating the stove surface burnt cooling.

The guidance of air is also used to preheat firewood before burning, so that the induction type in fuel and air shooting device is logical Wind can play the role of evaporator.The preheating of this firewood evaporates moisture from fuel, by firewood drying and prevents The many energy losses to evaporation water usually consumed in combustion chamber.Moist firewood or " dark green " firewood contain about The water of 50% weight, firewood contain the water of about 20% weight when suitably storing and spontaneously drying depending on environmental factor.This Introduction in text provides a kind of portable dress for heating " more dark green " or the biomass cut down recently in advance before burning It sets, evaporation water and to expand potential fuels sources from firewood when close to burning.

Many advantages of rocket stove are the reason of becoming more and more popular in the user for liking firewood stove.These advantage packets Include in terms of efficiency, safety and environment influence to existing biomass camp stove, bonfire and combustion gas camp stove into Row improves.Household energy is generated (often close due to most of China, India and African family's dependence solid fuel consumption In enclosed or improper ventilation space), thus environment relevant to biomass consumption and safety are presented and are needed for a long time The problem of improvement, but never can satisfy demand.

The reduction of ash and cigarette caused by rocket stove burning (when reaching optimum working temperature) demonstrates its efficiency.One Part Research Literature in 2007 has recorded in sub-Saharan Africa area, substitutes traditional firewood furnace with rocket stove Tool reflects this efficient.These stoves are not folding, heat-insulated stoves, these stoves are in past some months or several It is used to cook thousands of canteens in year.Related four agencies reports are tested with field to say, after this stove, The purchase of wooden fuel reduces 57%-71% (rocket stove influences research, in August, 2007 in ProBEC school lunch service).

The firewood stove of many types camps stove and field survivorship stove has come out and achieved patent, however this Do not have a kind of to combine feature high-effect, foldable, easy to use referred to herein in a little stoves.It is many foldable Firewood stove has been achieved with patent, but bulky when their foldings, and the possible of thermal insulation layer that cannot provide itself makes With, such as: it authorizes the United States Patent (USP) 4,069,806 (1978) of Landry and authorizes the United States Patent (USP) 5,119,799 of Cowen (1992).In addition, not utilize rocket stove constantly to add fuel excellent without removing bowl this design for many firewood stoves Gesture, or the fuel of addition is confined to extremely tiny branch and small wooden, this is rapidly consumed without removing bowl, Such as: the United States Patent (USP) authorizing the United States Patent (USP) 0284047A1 (2011) of Johnson et al., authorize Cedar et al. 0083946A1 (2010), or authorize the United States Patent (USP) 5,842,463 (1998) of Hall.

Other firewood furnaces or stove of camping design and do not use any kind of thermal insulation layer, do not provide such as religion herein Potential thermal insulation layer is brought up in gathering materials on the spot in place to use for finding in leading, or lights most of two so that realizing by design Lasting temperature required for the wood gas of secondary burning is difficult or is unable to complete, in addition, these stoves fail burning surface with The safety benefit of heat shield is provided between user.Such as: the United States Patent (USP) 8,261,731B2 (2012) of Marsh is authorized, The United States Patent (USP) 4,971,045 (1990) of Probst is authorized, or authorizes the United States Patent (USP) 0204852 (2012) of Boucher.Some Although the design advantage of rocket stove concept is utilized in firewood stove, but not foldable, such as: authorize DeFoort's et al. United States Patent (USP) 0258104A1 (2010).Many other firewood stoves need consumable ingredient to operate, and have and rely on power supply Or the defect of of the fuel of shop purchase itself.Such as United States Patent (USP) 0165769A1 improves efficiency and fuel using air blower Consumption, but its defect is to need power supply.It is other stove very light in weight, portable or foldable, but fuel slug is needed to grasp Make.It authorizes the United States Patent (USP) 0217657A1 (2005) of Anue and authorizes the United States Patent (USP) 6,851,419B2 (2005) of Reiner Belong to this kind.Each of these stoves have the advantages, but so far as is known, there is no a stove to mention in these stoves The advantage for having supplied the foldable rocket stove of introduction herein to design.

Summary of the invention

It please know, I, Frederick Taylor Douglas shock woods, United States citizen lives in the state of Wisconsin Cloth Lang County Green shellfish has invented a kind of folding second-time burning biomass furnace.The present invention provides a kind of furnace shell, furnaces The component of tool is inserted into and is assembled in the furnace shell.The present invention makes operator exempt from direct catalytic combustion chamber by following manner: making Operator can construct combustion chamber by the way that fuel and air shooting device and fume extractor to be assembled in furnace shell.The present invention is User provides following mechanisms: the mechanism is using the picnic original material in place (such as: soil, stone) to fume extractor It is thermally shielded with fuel and air shooting device, the heat-barrier material huge or heavy without transportation volume.The present invention provides Following portable mechanisms: the mechanism preheats biomass before burning, to evaporate water from firewood in the close burning of firewood Part, with by higher operating temperature raising efficiency, and potential fuel source is expanded to the wood of moister " more dark green " Bavin.The present invention provides a kind of light-duty and efficient biomass furnace, which remains the concept of rocket stove, but It is that its construction is portable and foldable.

One embodiment described herein has reached 1700 ° of Fahrenheit or more of temperature using waste wood, this considerably beyond Temperature needed for reaching second-time burning and lighting wood gas.In addition, embodiment described herein fold into substantially large screen pen The size for remembering this computer, than saving 90% or more storage space when expansion.Compared to many other rocket stoves on sale on the market, Embodiment described herein also providing advantage in terms of stability, and the frequent furnace foot or tripod branch by welding of other stoves Support.In addition, roomy, the rectangular pedestal of most of embodiments herein may less topple and the fuel of the non-cinder of ember inclines It is poured on the region of mistake.

The raising of efficiency is to improve the direct result of burning, and which reduce the generations of imperfect combustion product.These are harmful Product includes the generation of hydrocarbon and carbon monoxide, and sucking both of which can generate negative effect to health.World health organization is pre- It surveys, there are 270 ten thousand to 300 ten thousand people to die of the produced pollution that uses solid fuel every year.Reduce manufacture these pollutants can be to making The health care belt of user carrys out favorable influence.

However, such as rocket stove on sale on the market at present, the stove mentioned in above-mentioned African studies or too heavy is wanted It is bulky, and can not be as camping, go on a hike or the ideal solution of field survivorship.It is lesser in these stoves Model often weighs 15 pounds or more, and needs several square feet of luggage space.In addition, most of on the market at present declare Portable rocket stove is different from embodiment listed in this article, does not relate to fume extractor and fuel and air intake fills It is heat-insulated between setting.With rocket stove at present on the market on the contrary, embodiment as described herein provide it is one lighter, tighter The solution gathered is designed better than the various rocket furnaces using rocket furnace concept at present on the market.

Equally, it aiming at the problem that there is demand in a morning but there is no supply in field survivorship articles field, devises closed Theory.When massive blackout occurring or water pipe bursts apart, clean water source possibly can not be obtained for culinary art and sanitary use. For example, millions of Americans has found that they cannot get clean water, sometimes when the special Linne of card and Sang Di hurricane attack Such case can take several days.Often, local resources and clean water is had no lack of, but not ready-made device disappears water Poison, especially in urban environment, there bonfire is more infeasible.Embodiments as presented herein makes a kind of light-duty, efficient burning The mechanism of waste wood becomes possible, can be obtained by water purification without electric power or combustion gas or is cooked.In addition, described herein set Closed combustion chamber in meter can reduce the load that second-time burning flame is surprisingly generated for burning outdoor in urban environment Sorrow.

It is market most of portable rocket stoves on sale using main furnace shell to keep apart user and combustion chamber Not available additional security feature.This characteristic reduces the possibility that unexpected burning occurs during using stove.In addition, The thermal insulation layer of embodiment described herein makes it possible to gather materials on the spot in spot camping, such as, but not limited to soil, stone or sand Son.This heat-barrier material adds inside main furnace shell around combustion chamber, fuel and air shooting device and fume extractor, to reach To higher operating temperature and efficiency.This enable foldable rocket stove as described herein than the expansion of beta version and Heat-insulated rocket stove hauled weight mitigates significantly.This depends in part on the specific dimensions of heat-barrier material and rocket stove used And change.
