Abstract
The utility model provides a deflagration preventive burner which relates to the improving technology of components of gas water heaters. The utility model discloses a novel deflagration preventive burner which can reduce the deflagration probability and comprises a fire row and nozzles corresponding to the fire row. The nozzles comprise ignition nozzles and non-ignition nozzles, and the diameter of the ignition nozzle is 1.02 to 1.1 times as long as that of the non-ignition nozzle, wherein the diameters of the non-ignition nozzles are determined according to heating loads and burning conditions. The novel deflagration preventive burner has the advantages of simple structure and low cost. On the basis of the existing burner, only the diameters of the ignition nozzles are increased properly to enhance the local gas concentration in an ignition zone, so that the deflagration phenomenon is improved when a gas water heater is ignited.
Description
Technical field
The utility model relates to a kind of parts of domestic gas-fired water heater, particularly a kind of burner of new type explosion proof combustion.
Technical background
When gas ignition burns; " detonation " phenomenon takes place through regular meeting; " detonation " is meant that combustion gas is in the volumetric expansion after lighting of combustion chamber inner accumulated; even reach the situation of blast; the probability that " detonation " takes place is little, but harmfulness is very big, need urgently improve this situation; " detonation " situation mainly contain following two kinds of situations, the firstth, owing to passing fire insufficient causing " detonation ".Also having a kind of situation is to light a fire not fire, because the seed region gas concentration is very little, fails to catch fire, and when point catches fire, has been full of combustion gas in the whole combustion chamber, forms " detonation " at once.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of burner that improves the new type explosion proof combustion of seed region gas concentration is provided.Particularly, reduce the probability of ignition deflagrating of hot at second kind of above-mentioned situation.
The technical scheme of the burner of the anti-detonation of the utility model is: a kind of burner of new type explosion proof combustion, comprise fire row and arrange corresponding nozzle with fire, it is characterized in that: described nozzle comprises ignition burner and non-ignition burner, and the diameter of ignition burner is 1.02 to 1.1 times of non-ignition burner diameter.
Especially, the diameter of described ignition burner is 1.05 to 1.08 times of non-ignition burner diameter.Non-ignition burner quantity is got big value for a long time, otherwise gets the small value.
The beneficial effects of the utility model are, the diameter that can on the basis of existing burner, suitably add too corresponding ignition burner with igniting fire row, improve the gas concentration on seed region part (igniting fire row top), thereby improved " detonation " phenomenon when gas heater is lighted a fire.The non-ignition burner diameter corresponding with non-igniting fire row decided according to thermic load and combustion conditions.
Description of drawings
Accompanying drawing 1 is the burner part-structure schematic diagram of the anti-detonation of the utility model.
The specific embodiment
As shown in Figure 1, in the burner part-structure schematic diagram of the anti-detonation of the utility model, igniting fire row 1 two ends are respectively equipped with igniting pin 2 and ignition burner 3, the diameter D of ignition burner 3 is 0.96mm, the diameter d of the non-ignition burner 4 of its both sides is 1.01mm, if the diameter D of ignition burner 3 is 1.26mm, the diameter d of the non-ignition burner 4 of its both sides can be processed into 1.285mm to 1.386mm, like this when igniting, can increase the concentration of igniting fire row top combustion gas, the igniting pin can in time be lighted a fire, and improves ignition success rate, reduces the generation of " detonation " situation.
Claims (2)
