Abstract
The utility model discloses a flame cooling device capable of reducing discharging amount of nitrogen oxides in a gas range, 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 new-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 nitrogen oxides of the gas range can be reduced about 30 percents by the utility model.
Description
The utility model belongs to a kind of device that reduces nitrous oxides concentration in the gas-cooker flue gas.Amount of nitrogen oxides in the gas-cooker smoke evacuation of using at present 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-cooker nitrogen oxide emission to the public.This device to the normal use of gas-cooker without any influence.
To achieve these goals, mode was finished below the utility model adopted:
On the burner of original gas-cooker, be positioned at flame one or both sides installing annular or vertical bar shaped flame cooling body.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-cooker is equipped with the annular flame cooling body, and Fig. 2 is a vertical view, and Fig. 3 is a cutaway view, and Fig. 4 is an installation diagram.
1 is the burner for gas stove head among the figure, the 2nd, and the flame cooling body, the 3rd, the burner fire hole, the 4th, burner fire lid, the 5th, support.
Embodiment: use on Beijing Inst. of Civil Engineering ﹠ Arch's one household liquified oil gas kitchen, the gas-cooker rated heat input, rated heat load is 3.3KW, annular flame cooling body iron wire processing and fabricating.Under rated heat input, rated heat load, the flame cooling body is installed after, discharged nitrous oxides concentration is 84ppm in the flue gas, when the flame cooling body is not installed in the flue gas discharged nitrous oxides concentration be 120ppm, concentration of emission reduces by 30%.
This shows, the utlity model has the remarkable result that reduces discharged nitrous oxides.
Claims (2)
1. flame cooling device that reduces the gas-cooker discharged nitrous oxides, above burner for gas stove fire hole side, add the flame cooling body, it is characterized in that: the flame cooling body is fixed on burner head or is supported on other positions of gas-cooker, 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: add an annular or bar shaped flame cooling body on original or newly-designed gas-cooker, the flame cooling body directly is contained in burner for gas stove fire hole side top, also can be processed into one with burner.
