Abstract
The utility model provides a low-carbon energy efficient combustor that can enable gas to be combusted more fully, and consequentially reduce harmful substance in discharged waste smoke, heat generated and environmental pollution, prolong the service life of a cooking range and decrease the noise of flame. The combustor comprises a combustion chamber, a mixing cavity and a waste heat recovery body that are sequentially connected from the top down, wherein the combustion cavity comprises a fire bowl and an air jacket I on top of the mixing cavity; the combustion cavity is at the uppermost end of the whole combustor and keeps a certain gap with the bottom of a pan; the mixing chamber in the middle of the whole combustor is used for premixing gas with fresh air in the cavity to form standard combustion gas; and the waste heat recovery body uses a heat exchange device installed in an exhaust duct of the cooking range to recover the residual heat in the discharged waste gas, and uses the residual heat in the discharged waste gas in a flue to heat the fresh air blown in the mixing cavity by a fan.
Description
Technical field
The utility model belongs to the burner field, relates in particular to a kind of low-carbon high-efficiency energy-saving burner, goes for all kinds of gasifiable class A fuel As, as: fuel gas such as liquefied petroleum gas, coal gas, natural gas, various synthesis gas.
Background technology
Referring to Fig. 1, traditional air blast range adopts open wide direct-fired.Form by two parts: the burning cavity (see figure 1) that burner inner chamber body and wind cover form.Directly bright wind is blown into burner inner chamber body (forming) from the burner bottom by air blast by shell and wind cover, the through hole that sees through on the wind cover sidewall (has a plurality of through holes, the quantity difference in the burner hole that different manufacturers is produced, wind cover sidewall and bottom surface form a cylindrical combustion chamber that opens wide above the bottom lock) blow out the burner inner chamber body, the combustion gas of the bright wind that blows out (gas outlet in main combustible pipe road is located immediately at the combustion chamber bottom that the wind cover forms) input combustion chamber together from the main combustible pipe road mixes atmosphere and burns.
There is following shortcoming in prior art:
1) fuel gas buring is insufficient, contains harmful substances such as a large amount of carbon monoxide, nitrogen oxide in the useless flue gas of discharging, can produce a large amount of carbon distributions.
2) fuel gas buring is insufficient, reduces the heat that produces behind the fuel gas buring.
3) most heat is along with the useless flue gas of discharging is drained, and the thermal efficiency is low, and contaminated environment influences the service life of kitchen range again.
4) the flame combustion noise is big
Summary of the invention
The utility model provides a kind of low-carbon high-efficiency energy-saving burner, it can make fuel gas buring more abundant, thereby reduce the harmful substance in the useless cigarette of discharging, improve the thermal efficiency, reduce the EGT that is discharged, reduce environmental pollution, prolong the service life of cooking stove and can reduce the flame burning noise.
A kind of burner, comprise the combustion chamber, hybrid chamber, the waste heat recovery body that connect successively from top to bottom, combustion chamber comprises that fire bowl and the wind cover I that is positioned at the hybrid chamber top form jointly, and described combustion chamber is positioned at the top of whole burner, and the fire bowl upper edge and the bottom of a pan keep a fixed gap; The described middle part that makes combustion gas and bright wind premixed within it formation standard mixing of combustion gases chamber be positioned at whole burner; Described waste heat recovery body comprises being installed in the cooking stove exhausting duct to reclaim and is discharged the heat-exchanger rig that waste heat heater blower in the waste gas is blown into the bright wind of hybrid chamber.
Wherein, described fire bowl is made by tubaeform refractory material.
Wherein, described fire bowl is movable.
Wherein, the described heat-exchanger rig that is installed in the cooking stove exhausting duct is taked the mode of fan coil.
This burner has kept consistent with the flame combustion form of traditional direct-fired burner, makes the cook in use keep original operating habit.By preheating bright wind and the noise that the more abundant reduction flame combustion of fuel gas buring is produced of the dynamic combustion behind the combustion gas equivalent premix.The heat that utilizes heat-exchanger rig that fuel gas buring is produced has obtained the secondary utilization, and the heat in the discharging flue gas that reduces had both protected stove also to improve cook's operating environment.Under equal situation, can effectively reduce the consumption of combustion gas by above improvement, reach and save other emission of harmful substances that gas consumption reduces carbon dioxide and burning generation; Reduced the EGT that is discharged, reduced the noise that flame combustion produces, the operating environment that not only can greatly improve the cook simultaneously but also prolonged service life of cooking stove.
Description of drawings
The structure chart of accompanying drawing 1 traditional open type direct combustion air blast range;
Accompanying drawing 2 is the structure chart of the preferred forms of the utility model burner;
Accompanying drawing 3 is the job step flow chart of the utility model burner.
The specific embodiment
Referring to Fig. 2, the utility model burner is divided into three parts: the combustion chamber of Lian Jieing, hybrid chamber, waste heat recovery body successively.The fire bowl that combustion chamber is made by tubaeform refractory material is formed jointly with the wind cover I at hybrid chamber top, and the top and the bottom of a pan that are positioned at whole burner keep a fixed gap, and the fire bowl is movable.Hybrid chamber: combustion gas and the premixed in this cavity of bright wind, form the standard burning gases, be positioned at the middle part of whole burner.Waste heat recovery body: utilize the heat-exchanger rig that is installed in the cooking stove exhausting duct to reclaim the waste heat that is discharged in the waste gas, then the waste heat heater blower in the waste gas that emits in the flue is blown into the bright wind of hybrid chamber, be positioned at the end of whole burner.Be installed in heat-exchanger rig in the cooking stove exhausting duct and take the mode of fan coil.
Understand the utility model for ease of those of ordinary skills, special job step with the utility model is explained as follows.
Referring to Fig. 3, the bright wind that step 1) is injected by air blast reclaims the waste heat that is discharged in the waste gas by the heat-exchanger rig (adopting the mode of fan coil) that is installed in the cooking stove exhausting duct, injects in the hybrid chamber.Step 2) the bright wind after the heating of process waste heat recovery body enters the equivalent premix before hybrid chamber burns with the combustion gas that enters by main gas tube, and mist enters combustion chamber then.The burning gases for the treatment of after heating of step 3) process and the premixed take fire in the bottom of burning zone (wind cover I), and flame is moulding by the fire bowl, are close to the bottom of a pan burning.
