Description
Technical field
The utility model relates to a kind of heater, is a kind of gas furnace that fuel gas Thorough combustion can be made to recycle again wasted energy specifically.
Background technology
Along with the raising of living standards of the people and the change of natural conditions, people heat up water, cook, cooking generally uses gas heating.Reducing environmental pollution to reduce heating cost, being badly in need of there is a kind of gas combustion apparatus of science to adapt to the requirement of people.
The process of combustible (oil gas) heat medium is a conversion process of energy.According to law of conservation of energy, in energy transfer process, need realize energy-conservation, be nothing but energy storage body is played one's part to the full and transmits in (conversion) process at each to reduce the loss as far as possible, make by obtaining more heat by object.This device of gas burner is a typical energy conversion device.Make this device energy-conservation, following several relevant issues must be solved, energy just can be made to play one's part to the full, realize energy-conservation and reduce environmental pollution, keep clean and the service life of prolongation stove and accessory.
One, before burning, gases at high pressure (butane) or the necessary gasification of fully expanding of natural gas absorb fully enough oxygen and Re Lai raising own temperature, make it to reach burning point.In this course, a large amount of heat energy to be absorbed fast.Within very short time, how making burning gases obtain maximum heats and continuing condition needed for transmittance process under not affecting is a vital ring.
Two, combustible must the short time among a small circle in Thorough combustion discharge all energy.
Three, in whole transmittance process, the loss of energy is dropped to minimum.
Four, in transmission (conversion) process of energy, the loss of energy is difficult to avoid, and will reclaim wasted energy as far as possible be utilized.
The achievement that inventor has used the time of 10 years to use for reference others passes through numerous experiments, make this utility model product, make the utilization ratio of oil gas heat energy reach more than 49-64%, and the utilization ratio of now popular on the market various stove and accessory heat energy is only between 33-46%.And heatable substance is fewer, container is also less.The popular stove and accessory waste heat energy in present market is more, and the utilization rate of this novel product to heat energy is higher.
Summary of the invention
The purpose of this utility model is to provide that a kind of firepower is violent, fire is evenly distributed and the gas furnace that the utilization ratio of energy is higher.In order to achieve the above object, the utility model have employed following technical measures:
A kind of gas furnace, furnace end body is arranged on furnace panel, prop up and be placed on furnace panel and cover on furnace end body periphery, first air supply channel connects the outer shroud burner port that burner ring-type is laid through the circular passage of the first air supply pipe, furnace end body, the second air supply channel connects the inner ring burner port of burner through the inner passage of the second air supply pipe, furnace end body; Wherein, the front end of the first air supply pipe has the mixed once room that the first fresh air inlet forms the first air supply channel, the secondary mixing chamber that the second fresh air inlet forms the first air supply channel is connected in inner end, second air supply pipe has the first mixing chamber that the 3rd fresh air inlet forms the second air supply channel, and furnace end body inner passage has the secondary mixing chamber that the 4th fresh air inlet forms the second air supply channel.
In above-mentioned, the outer burner port that inner ring burner port is laid by double-layer circular and central burner hole form, and wherein aperture, central burner hole is 6-10 times of outer burner port aperture; The cross section of burner is ∩ type; Burner edge covers furnace end body outer rim and together with spinning with furnace end body; Support is made up of annular ledge and 3-4 the supporting member be fixed on above annular ledge, wherein has multiple ventilating opening below annular ledge.
The utility model tool has the following advantages:
Two air supply channels independently air feed air intake, with two air nozzles, each air supply channel works alone, and is conducive to the adjustment by fiery form and firepower demand like this.
Be ∩ type because of burner and be an entirety, upwards, a large-scale combustion hole is opened in centre to burner port, so because air-out is large when using, flame is effectively large and high, material is thus formed periphery vacuum, therefore the flame of periphery more effectively can be attracted to centre, flame is concentrated, central temperature increases, as long as give suitable oxygen like this, combustion gas gas is energy Thorough combustion in time just, among a small circle, produce a large amount of heat energy (as combustion gas weldering, burning torch).Because burner port is all lead directly to up and down, so flare is directly to upper, its flame is stronger than the flame of inclined hole or side opening stove, destroy the laminar flow layer in heat trnasfer simultaneously, improve capacity of heat transmission, accelerate the transmission speed of heat energy, decrease hot loss of energy, simultaneously also solve use conventional oven, the defect that the temperature of pot central temperature is on the low side periphery is too high.
Furnace is the place of fuel combustion, and the furnace of gas burner is the space surrounded by furnace panel, burner and annular ledge.Furnace panel in the utility model, burner and annular ledge constitute a semi-enclosed space, ventilating opening is had below annular ledge, these ventilating openings to cross wind area large or little all bad, large cooling effect is played to stove, little fuel can not get sufficient oxygen can not Thorough combustion in time, is directed at the waste of fuel.So these ventilating openings not only play a part the combustion-supporting too much cryogenic gas of restriction that also plays a part of ventilation and enter furnace, decrease the consumption of heat energy, improve the utilization rate of energy.Annular ledge is stop entering of Cryogenic air on the one hand, reduces heat energy and leaks, preserve in-furnace temperature, improve the burning level of fuel gas.Utilize heat radiation that in-furnace temperature is improved on the other hand, make the corresponding minimizing of combustion gas, save fuel, this is also the recycling of above-mentioned wasted energy.This is also be different from common traditional tripod, four foot supports, and furnace opens wide the place that heat energy runs off arbitrarily.
The utility model adopts two-stage mixed gas supply.First be that gases at high pressure are sprayed by the nozzle of diameter 0.5 ~ 0.7, now the temperature of gas is very low, needs to absorb a large amount of heat to the temperature improving self to reach burning-point.In order to allow combustion gas obtain enough temperature and oxygen, so the mixing of its design forming two-stage is joined the form of (suction) gas.The effect of the first order mainly allows combustion gas heat up, and the cavity of this one-level can not do too much, and material is the good copper of heat conductivility preferably; The effect of secondary mainly obtains enough oxygen, and the cavity of this one-level should do as far as possible large, allows the abundant expansion buffer of combustion gas, absorbs more oxygen.
Prove that the utility model fuel combustion is abundant through test and long-term practicality, decrease the discharge of pernicious gas, be conducive to environmental sanitation.Scientific structure, technology maturation is easily promoted.Elegant in appearance, easy to clean and durable, easy to operate.The utility model not only can use liquefied petroleum gas, also can use natural stone oil gas, coal gas, biogas, biogas etc.Both be applicable to family, be also applicable to catering trade, there is adaptability widely.
