Abstract
The utility model discloses a gas burning device of a water heater with low NOx discharging amount, which is characterized in that a flame cooling body is additionally arranged at the side upper part of a flame hole of an original or a newly designed gas range burner to cool the flame. The supply of secondary air can be controlled, and the formation of nitrogen oxides can be suppressed. The discharging amount of the NOx of the gas range can be reduced about 45 percents by the utility model.
Description
The utility model belongs to a kind of device that gas heater is realized low nitrogen oxide burning.At present the discharge capacity of the gas heater nitrogen oxide that uses is all very high, when flue gas directly is disposed to when indoor, can be detrimental to health.Drain into when outdoor, pollute the environment.
The purpose of this utility model is to release a kind of device that reduces the gas heater nitrogen oxide emission to the public.This device to the normal use of gas heater without any influence.
To achieve these goals, mode was finished below the utility model adopted:
On the burner of original gas heater, be positioned at flame one or both sides installing annular or vertical bar shaped flame cooling body.This flame cooling body can be made of one with burner on newly-designed gas heater.This flame cooling body is made with heating resisting metal or nonmetal tubing or bar or silk, and its cross section can be arbitrary shape, as circular, square, triangle, trapezoidal etc.It can cool off flame, and can also control auxiliary air and supply with, thus the generation of inhibition combustion process nitrogen oxide.
Fig. 1 is the front view that gas heater is equipped with vertical bar shaped flame cooling body low nitrogen oxide burner, and Fig. 2 is a vertical view, and Fig. 3 is a cutaway view, and Fig. 4 is an installation diagram.
1 is gas heater burner's head among the figure, the 2nd, and the flame cooling body, the 3rd, the burner fire hole, the 4th, support.
Embodiment: use on Beijing Inst. of Civil Engineering ﹠ Arch's one household liquified oil gas water heater, the water heater rated heat input, rated heat load is 10.3KW, vertical bar shaped flame cooling body nickel filament processing and fabricating.Under rated heat input, rated heat load, the flame cooling body is installed after, discharged nitrous oxides concentration is 120ppm in the flue gas, when the flame cooling body is not installed in the flue gas discharged nitrous oxides concentration be 220ppm, concentration of emission reduces by 45%.
This shows, the utlity model has the remarkable result that reduces discharged nitrous oxides.
Claims (2)
1. a gas heater low nitrogen oxide burning device adds the flame cooling body above gas heater burner's fire hole side.It is characterized in that: the flame cooling body is fixed on burner head or is supported on other positions of gas heater, and must not the overslaugh combustion gas flow out from fire hole.
2. by the described device of claim 1, it is characterized in that: on original or newly-designed gas heater, add an annular or vertical bar shaped flame cooling body, the flame cooling body directly is contained in gas heater burner's fire hole side top, also can be processed into one with burner.
