Abstract
The utility model discloses a full premixed burner of a gas water heater, which is composed of a plurality of burning units. Each burning unit comprises a burner head, a cavity body and a nozzle, wherein the burner head is communicated with the cavity body which is provided with a mixing pipe and the nozzle is positioned on the opening position of the mixing pipe. A gas inlet of the cavity body is provided with a mixing pipe, and the gas inlet of the cavity body is communicated with the cavity body through the mixing pipe. The utility model has the advantages that the gas can instantly finish combustion on the inner flame surface because the gas and the air are completely and uniformly mixed before being fired, and as a result, CO and NOx in the fume can be completely burned without being formed. Thus, the content of CO and NOx in the fume can be effectively controlled under very low level. As a consequence, the utility model saves energy sources, besides, the utility model is favorable to environment protection. Meanwhile, owing to the sufficient combustion assurance, the utility model raises the combustion efficiency.
Description
Technical field
The utility model relates to a kind of burner of gas instantaneous water heater, more specifically says so to relate to a kind of burner that is placed in the air blast type gas instantaneous water heater.
Background technology
Gas instantaneous water heater of the prior art adopts atmospheric burning type mostly, needs to provide a certain proportion of primary air before fuel gas buring, combustion gas is mixed in cavity after, again at burner head and auxiliary air catalytic combustion.The primary air amount is about about 60%, and when burning, influence owing to the relation that is subjected to an auxiliary air and combustion gas proportional quantity, the problems such as carbon monoxide (CO) content superelevation that easily produce incomplete combustion and cause, the concentration of nitrogen oxide (Nox) is also higher in the flue gas of burning back generation simultaneously, so not only waste a large amount of combustion gas, but also polluted environment.
The utility model content
The purpose of this utility model provides a kind of burning more complete in order to solve above-mentioned deficiency exactly, and CO and the low a kind of fully-premixed gas heater burner of NOx content in the flue gas.
The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:
A kind of fully-premixed gas heater burner, it is made of a plurality of fuel elements, each fuel element includes burner head, cavity and nozzle, burner head is connected with cavity, on cavity, be provided with mixing tube, nozzle is positioned at and mixes mouth of pipe place, and the air inlet place of described cavity is provided with mixing tube, and this mixing tube is connected the air inlet of cavity with cavity.
Burner is made up of plural independent burning unit combination.
Described burner head is the ceramic material plate of the small pore-like of gathering.
The surface area size of described burner head has nothing in common with each other.
The diameter and the insertion depth of mixing tube have nothing in common with each other in the described cavity.
The air inlet place of described cavity is provided with the air blast system, and the air of certain pressure is provided by blower system.
Be provided with dividing plate in the described cavity.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: the combustion gas that is provided by nozzle is mixed in the mixing tube at the mixing mouth of pipe and air, air further mixes in cavity with combustion gas under blower system pressure, goes mist into certain pressure.The required air that burns is sent into by blower system fully, be that combustion air is primary air entirely, need not auxiliary air, the primary air amount is more than 100%, after burner head surface ignition burning, because combustion gas fully evenly mixes before catching fire with air, combustion gas moment on the internal flame face has been finished burning, cause that CO and NOx also have little time to generate promptly by completing combustion in the flue gas, make CO and NOx content in the flue gas can effectively be controlled under the low-down level, thereby not only saved the energy, but also utilized environmental protection.Simultaneously owing to the efficiency of combustion that fully makes that has guaranteed burning improves.The unit are of the burner head density height of pore size distribution of getting angry in addition, the thermic load of its unit are also is higher than common burner, helps making the burner volume to dwindle.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
The specific embodiment
By illustrated in figures 1 and 2, a kind of fully-premixed gas heater burner, form by plural individual burner unit combination, each burner unit includes burner head 1, cavity 2, mixing tube 3 and nozzle 4, burner head 1 is connected with cavity 2, burner head 1 is the ceramic material plate of the small pore-like of gathering, for the ease of regulating the size of firepower, surface area size that can burner head 1 is set to have nothing in common with each other, cavity 2 is provided with air inlet 201, nozzle 4 is positioned at this air inlet 201 places, air inlet 201 places at cavity 2 also are provided with the air blast system, be used for blasting in the cavity 2 of force air fully mixed with combustion gas, mixing tube 3 is arranged on air inlet 201 places of cavity 2, this mixing tube 3 is connected the air inlet 201 of cavity 2 with cavity 2, for combustion gas in the cavity 2 and more effective the mixing of air energy, the diameter and the insertion depth of mixing tube 3 in the cavity 2 can be arranged to have nothing in common with each other, dividing plate 5 can also be set in cavity 2, increase the mobile performance of gaseous mixture in the cavity 2, what make it to mix is more even.
The combustion gas that is provided by nozzle 4 is mixed in the mixing tube 3 at the mixing mouth of pipe and air, air is further mixing with combustion gas air in cavity 2 under the blower system pressure, the required air that burns is sent into by blower system fully, be that combustion air is a primary air, need not auxiliary air, the primary air amount is more than 100%, the small pore-like ceramic material plate of burner head 1 for gathering, combustion gas mixes back effusion burning in the aperture on ceramic wafer with air, heat mainly produces with forms of radiation behind the flameholding, i.e. infrared radiation.Because combustion gas fully evenly mixes before catching fire with air, during burning in the internal flame of flame moment finished combustion process, cause in the flue gas CO and NOx to have little time to generate and promptly finish burning, make CO and NOx can effectively be controlled under the low-down level, the density height of pore size distribution because unit are is got angry in addition, the thermic load of its unit are also is higher than common burner, helps improving the thermal efficiency of burning.
