Abstract
The utility model discloses an air mixes low -nitrogen oxide combustion ware in advance relates to natural gas burner technique, is by the shell, mixes the awl and light a coal fire with firewood a section of thick bamboo and constitute, and it mixes, and shell cavity is arranged in to the awl, the axis that mixes awl and shell be same straight line, and the lower extreme opening of shell the section of thick bamboo of lighting a coal fire with firewood, is mixed the lower upper end fixed connection along circumference and isolating barrel of awl in the section of thick bamboo of lighting a coal fire with firewood through the screw rod fixed connection more than two. The utility model discloses an air mixes low -nitrogen oxide combustion ware in advance, simple structure, reasonable in design have increased isolating barrel on current combustor, and messenger's flame complete combustion is thoughtlessly burnt in advance in the burning that once mixes in advance that isolating barrel is inside with the outside secondary of isolating barrel. Gas air mixing is even, the burning is abundant, combustion efficiency is high and reduced the temperature of high temperature point, falls low nitrogen oxide and discharges, protect the environment, and the new direction of natural gas combustion technology.
Description
Technical field
The utility model relates to neat gas burner technology, relates in particular to air pre-mixing low nitrogen oxide burner.
Background technology
Along with industrial expansion, environmental pollution constantly aggravates, and countries in the world environmental protection department requires strict to the discharge standard of Industrial Boiler. The usage quantity of Industrial Boiler is larger at present, and existing combustion of industrial boiler device exists certain drawback, and major embodiment is: the first, the nitrogen oxides in effluent content of discharge is larger, has aggravated environmental pollution; The second, burner combustion gas and air mix after disposable burning, gas-air mix uneven, burn insufficient, efficiency of combustion is low; Three, existing burner head structural design is unreasonable is also to cause one of inadequate reason of burning.
Utility model content
The utility model is intended to for the deficiency existing in background technology, and the air pre-mixing low nitrogen oxide burner providing.
Air pre-mixing low nitrogen oxide burner of the present utility model, to be formed by shell, composite cone and the cylinder of lighting a coal fire with firewood, the axis that its composite cone is placed in shell inner cavity, composite cone and shell is same straight line, the lower ending opening of shell by plural screw rod be fixedly connected with light a coal fire with firewood cylinder, light a coal fire with firewood cylinder in the lower of composite cone be fixedly connected with the upper end of isolating cylinder along circumference.
As further improvement of the utility model, the cone of described composite cone is uniform through hole with it.
As further improvement of the utility model, the external diameter of composite cone and isolating cylinder is all less than the internal diameter of the cylinder of lighting a coal fire with firewood, and isolating cylinder forms secondary air channel with the barrel gap of the cylinder of lighting a coal fire with firewood.
As further improvement of the utility model, shell and light a coal fire with firewood and be provided with gasket seal between cylinder.
As further improvement of the utility model, the length that the external diameter of isolating cylinder is identical with composite cone external diameter, the length of isolating cylinder is not more than the cylinder of lighting a coal fire with firewood.
Air pre-mixing low nitrogen oxide burner of the present utility model, simple in structure, reasonable in design, on existing burner, increase isolating cylinder, a premixed combustion of isolating cylinder inside and the secondary premixed combustion of isolating cylinder outside, make flame completing combustion. Gas-air mixes, sufficient combustion, efficiency of combustion are high and reduced the temperature of high temperature dot, reduces discharged nitrous oxides, and protection of the environment, is the new direction of combustion of natural gas technology.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
, be described further air pre-mixing low nitrogen oxide burner of the present utility model below in conjunction with accompanying drawing 1.
Embodiment 1
Air pre-mixing low nitrogen oxide burner of the present utility model, to be formed by shell 1, composite cone 2 and the cylinder 3 of lighting a coal fire with firewood, it is same straight line with the axis of shell 1 that its composite cone 2 is placed in shell 1 inner chamber, composite cone 2, the lower ending opening of shell 1 by plural screw rod 4 be fixedly connected with the cylinder 3 of lighting a coal fire with firewood, lighting a coal fire with firewood, cylinder the lower of 3 interior composite cones 2 is fixedly connected with the upper end of isolating cylinder 5 along circumference.
Embodiment 2
Air pre-mixing low nitrogen oxide burner of the present utility model, by shell 1, composite cone 2 and the cylinder 3 of lighting a coal fire with firewood form, its composite cone 2 is placed in shell 1 inner chamber, composite cone 2 is same straight line with the axis of shell 1, the lower ending opening of shell 1 is being fixedly connected with by plural screw rod 4 cylinder 3 of lighting a coal fire with firewood, lighting a coal fire with firewood, cylinder the lower of 3 interior composite cones 2 is fixedly connected with the upper end of isolating cylinder 5 along circumference, the cone of described composite cone 2 is uniform through hole 6 with it, the external diameter of composite cone 2 and isolating cylinder 5 is all less than the internal diameter of the cylinder 3 of lighting a coal fire with firewood, isolating cylinder 5 forms secondary air channel 7 with the barrel gap of the cylinder 3 of lighting a coal fire with firewood.
Embodiment 3
Air pre-mixing low nitrogen oxide burner of the present utility model, by shell 1, composite cone 2 and the cylinder 3 of lighting a coal fire with firewood form, its composite cone 2 is placed in shell 1 inner chamber, composite cone 2 is same straight line with the axis of shell 1, the lower ending opening of shell 1 is being fixedly connected with by plural screw rod 4 cylinder 3 of lighting a coal fire with firewood, lighting a coal fire with firewood, cylinder the lower of 3 interior composite cones 2 is fixedly connected with the upper end of isolating cylinder 5 along circumference, the cone of described composite cone 2 is uniform through hole 6 with it, the external diameter of composite cone 2 and isolating cylinder 5 is all less than the internal diameter of the cylinder 3 of lighting a coal fire with firewood, isolating cylinder 5 forms secondary air channel 7 with the barrel gap of the cylinder 3 of lighting a coal fire with firewood. shell 1 and the cylinder of lighting a coal fire with firewood are provided with gasket seal 8 between 3, the external diameter of isolating cylinder 5 length identical with composite cone 2 external diameters, isolating cylinder 5 is not more than the length of the cylinder 3 of lighting a coal fire with firewood, the length of isolating cylinder 5 is same or slightly shorter with cylinder 3 the length of lighting a coal fire with firewood, taking the lower limb of the cylinder of lighting a coal fire with firewood as benchmark.
