Description
Technical field
It is particularly a kind of using high heating value combustion gas as the non-pre- of fuel the present invention relates to gas fired-boiler heater element technical field
The novel super-low nitrogen combustion apparatus that mixed burning and premixed combustion are combined.
Background technology
NOx is a kind of important atmosphere pollution, is one of arch-criminal for triggering acid rain, haze.As China is controlled environmental protection
The increasing of reason dynamics and going deep into for energy-saving and emission-reduction policy, the limitation for industrial combustion gas emission of NOx of boiler amount is also increasingly strict,
Put into effect a series of standards of restriction boiler pollutant emission limits, monitoring and monitoring requirement, Beijing in 2017
Area must be decreased to 30mg/Nm on newly-built gas fired-boiler NOx emission3It is exactly one below.Therefore, industry is just in boiler flue gas
Carry out largely exploring and innovating in terms of the low-NO_x combustion technology of burner.
Win initial success at present and the drop nitrogen type gas burner of more application mainly there are two kinds：
One is the diffusion combustion formula burner more early released, also known as " non-premix burner ", be characterized in by combustion air with
Burner hearth is respectively fed in the case that combustion gas is unmixed in burner, because combustion air does not mix with combustion gas in burner internal
Close, so need the low nitrogen burning such as adapted flue gas recirculation ancillary technique to carry out drop nitrogen during this non-premix burner work, though
So have that itself is simple in construction, easily manufactured, flameholding, it is safe and easy to adjust the advantages that, but due to must be simultaneously
The low nitrogen burning such as adapted flue gas recirculation ancillary technique can just be effectively reduced boiler NOx discharge capacity, not only increase setting
Cost, and also result in the unstability for bringing increase to burn；
The second is the full premixed type surface combustion formula burner researched and developed in recent years, also known as " all-premixing burner ", be characterized in by
Combustion air is first mixed into homogeneous mixture comprehensively with combustion gas in the metallic cylinder before burner throat, then makes uniformly to mix
Gas only carries out abundant and efficient burning on metallic cylinder surface, rather than in round metal cylinder roasting, and because calory burning is equal
It is even, be not in extreme high heat in combustion chamber, thus the more non-premix burner of NOx discharge will lack, and flue gas can not be used to follow again
The low nitrogen burning ancillary technique such as ring.It is disadvantageous in that work applicable surface is not wide, and existing all-premixing burner is only applicable to
On the boiler that combustion gas and combustion air requirement are less, contribute less than 4t/h, it can just achieve effective control mixability and ensure
Safe operation, for the boiler contributed more than 4t/h, because the requirement of combustion gas and combustion air is big, combustion air and combustion gas ten thousand
One premix section head wire netting in mix it is uneven or occur block wire netting situation when, easily trigger detonation, thus
Cause the accident rate of high-power all-premixing burner higher, potential safety hazard be present.In addition, during existing all-premixing burner operation
Stricter is required to air distribution, tempering detonation easily occurs when the oxygen content in described homogeneous mixture is less than 6%, is higher than
De- fire easily occurs when 9%, and when longtime running is under elevated oxygen level homogeneous mixture state, wherein excessive combustion air
Caused heat during burning can be taken away, causes to produce boiler heat loss, reduces the thermal efficiency.So from operability, work
Make state controllability, safety in operation and stability angle consider, owe ideal, thus in the market using it is more still
The diffusion combustion formula burner more first to come out, i.e., non-premix burner.
Therefore super low-NO_x combustion technology only exists in the innovation stage constantly explored at present, technology is not also overripened, effect
Fruit also owes ideal.And gas fired-boiler realize NOx it is ultralow it is nitrogen discharged be the objective situation demand faced at present, and the realization of the demand
It must also start with from the initial ejection for reducing low NO NOx, replacement formula innovative design is updated to burner structure, is allowed to
Reduction NOx initial ejection amount can be ensured from the combination of theory and practice, is met conscientiously using the boiler of this burner
Increasingly harsh environmental requirement.
