Abstract
The utility model relates to a low nitrogen oxide burner. A gas chamber is provided with a gas inlet, the right side of the gas chamber is connected with a burning nozzle shell, an air inlet is arranged in the burning nozzle shell, a ceramic burning chamber is connected with the right end of the burning nozzle shell, a ceramic or metal outer shell is arranged outside the ceramic burning chamber, the gas chamber is connected to a central gas spray head through a connecting pipe, the central gas spray head reaches the left end of the ceramic burning chamber through the burning nozzle shell, the outer circumference of the right end of the central gas spray head is provided with metal spinning discs, and an ignition electrode is penetrated into the gas chamber from the outside of the gas chamber, is penetrated into the burning nozzle shell through the gas chamber and then is penetrated into the ceramic burning chamber; tertiary air is sprayed on the head of the burning nozzle through a gap between the ceramic burning chamber and the ceramic (or metal) shell and completes tertiary burning after being mixed, and consequently, the burner achieves the purpose that nitrogen oxides are reduced. The low nitrogen oxide burner can change the proportion of primary air, secondary air and tertiary air according to different working condition requirements; due to the adoption of a hollow gas multi-stage mixture burning structure, the generating quantity of nitrogen oxides in burning products is greatly reduced, and the effects of energy conservation and discharge reduction are realized.
Description
Technical field
The utility model belongs to gas burner, particularly a kind of low Nox burner.
Background technology
Along with the enforcement of country's " energy-conservation, as to reduce discharging consumption reduction " development strategy, more and more stricter to the restriction of harmful substance in the combustion product.Nitrogen oxide (NOx) content in minimizing and the reduction combustion product has become domestic and international combustion apparatus technical field and has first developed direction, and become an important indicator that defines the combustion apparatus technical merit.At present, most combustion apparatus adopt passage of combustion airs to infeed, and with before coal gas mixes, in the combustion chamber, use layer mode, expect to reach the fractional combustion purpose.Its shortcoming is, in the Actual combustion process, air-flow is because of factor affecting such as " boundary-layer ", " breathing heavily stream ", pressure oscillations, distributes and changes the result that can not reach classification or layering between very complicated, default air stream strand.The purpose that reduces nitrogen oxide (NOx) content in the combustion product more is difficult to realize.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of low Nox burner is provided.Use it to reduce and reduce nitrogen oxide (NOx) content in the combustion product.
The technical solution of the utility model is:
A kind of low Nox burner is characterized in that: a gas chamber is arranged, and gas chamber has gas entry; The gas chamber right side connects the burner shell, on the burner shell air intake is arranged, and the right-hand member that connects the burner shell is a ceramic-lined chamber, and ceramic burner is outdoor to be the shell of pottery or metal; Gas chamber, burner shell, ceramic-lined chamber, pottery or metal shell are linked in sequence; Gas chamber is connected to the center gas-jet by adapter, and the center gas-jet arrives in the ceramic-lined chamber left end by the burner shell, on the border outside the gas-jet right-hand member of center the metal spinning disk is arranged; Ignitor penetrates outside gas chamber, passes that gas chamber penetrates the burner shell, to penetrate ceramic burner more indoor.
Gas chamber, burner shell, ceramic-lined chamber and pottery or metal shell respectively for independently dividing body structure, have connector to fit together, and the insulation material liner is arranged in the burner shell.
On the gas chamber rear wall, flame monitor is arranged.At gas entry and air intake pressure measuring tie-in is housed.
Ceramic-lined chamber and its outer pottery or the shell of metal are double-deckers, and left part is cylindric, and the right part is the taper tubular.Metal spinning disk, ceramic-lined chamber and pottery or metal shell are formed the multistage mixed combustion structure of one, two, three wind.
Low Nox burner can change the ratio of one, two, three wind according to different operating mode needs.
The utility model effect is:
The utility model " novel low Nox burner " adopts the project organization of the multistage mixed combustion of sky-coal gas, reduces formation of nitrogen oxides in the combustion product greatly thereby reach, and realizes the effect of " energy-saving and emission-reduction ".Combustion air from burner shell air interface infeed and split into two passages of inside/outside with the form of one, two, three wind respectively with coal gas mixed combustion.According to the difference of kinds of gas, sky/coal gas characterisitic parameter and to the different requirements of formation of nitrogen oxides in the combustion product, can in structural design, determine the ratio of one, two, three wind, thereby reach best discharged nitrous oxides index.
1, combustion air as requested, infeeds from two passages with the ratio of setting in burner, and respectively with one, two, three wind form and coal gas mixed combustion respectively.Primary and secondary air is directly mixed with coal gas, and behind imperfect combustion, its imperfect combustion product mixes with the air that infeeds from the tertiary air passage again, reaches completing combustion.
2, the combustion chamber of carrying out first and second burning is made by high temperature ceramic material, and pottery (or metal) shell is arranged outside this combustion chamber, is the tertiary air passage, and plays the function of cooling ceramic-lined chamber simultaneously.
3, according to serviceability temperature difference, this burner bears high-temperature part (pottery or metal shell) and can adopt heat resisting steel or high temperature ceramic material to make, cancellation burner block, weight reduction, the convenient installation.
4, for the hot blast burning, INSULATION DESIGN in this burner adopts, thus reduce the burner housing temperature, improve operating environment, reduce thermal loss.
5, this burner is provided with electronic ignition electrode, flame detecting and flow detector, is convenient to combustion position is measured control; Ignitor can be extracted out at any time and be screwed into, convenient maintenance.
6, this burner is provided with two-way coal gas feed path, is convenient to carry out " big fire-little fire " control burning;
7, burner adopts the segmented modular structure, the convenient installation and maintenance.This burner is made up of pottery (or metal) shell, burner shell, ceramic-lined chamber, center gas-jet, spinning disk, gas chamber, liner etc.Various piece can be assembled arbitrarily, changes.
