Description
Technical field
The present invention relates to a kind of new combustion systems and gas-fired water heaters.
Background technique
Nitrogen oxides is common air pollutants, is often referred to nitric oxide and nitrogen dioxide, is often indicated with N02.One oxygen
Change the gas that nitrogen is a kind of colorless and odorless, is slightly soluble in water.Nitrogen dioxide can be rapidly gone in air.Nitrogen dioxide is irritating
Property, be at room temperature rufous, have stronger corrosivity and oxidisability, it is soluble easily in water, can be formed under effect of sunlight NO and
03.(nitrogen oxide mass concentration is about in 0.20mg/m3 in air) Pulmonary Function in Children and breathing system in nitrogen oxides high pollution area
Disease incidence of uniting is relatively high.Foreign countries' investigation shows the children that Respiratory symptoms and disease are suffered from using coal gas family
Ratio increases, and Pulmonary Function in Children is substantially reduced.Nitrogen oxides to human body generate damaging effect threshold mass concentration be 0.31~
0.62mg/m3。
NO formation mechanism: the NOx in flue gas is mainly NO, accounts for about 90% or so, is discharged into after atmosphere partially oxygen again
It is melted into NO2, therefore the formation mechanism of NOx is studied, mainly study the formation mechanism of NO.The generation form of NO has fuel type, temperature
Type and three kinds of fast temperature type.The NO that combustion process generates, mainly temperature mode NO (T-NO), some fast temperature
Type NO (P-NO), also known as instantaneous NO.T-NO formation mechanism: T-NO is that the nitrogen and oxygen in air generate at high temperature,
Its formation mechanism is to be proposed by former Soviet Union scientist Zeldvich in 1964.When the mixture combustion of combustion gas and air,
The key reaction process chemistry reaction for generating NO is as follows:
N2+ O=NO+N
N+O2=NO+O is (2)
By the experimental result of kinetics equation and Zeldvich, the formation speed of NO can be indicated are as follows:
D [NO]/dt=3 × 1014[N2][O2]1/2e-542COD/RT (3)
(3) in formula: [NO], [N2], the concentration (gmol/cm of [O2]-NO, N2, O22)
Mono- time (s) of t
T mono- reacts absolute temperature (K)
Mono- universal gas constant of R (J/gmol.K)
It is big to oxygen concentration, the few premixed flame of fuel, with the NO production quantity of (3) formula calculating, calculated result and reality
Border result is substantially uniform.But when being less than stoichiometric ratio, i.e. fuel overrich, there is also following reactions:
N+OH=NO+H
From (3) formula it is found that NO formation speed and T, [N2]、[O2] related, when being burnt in air due to combustion gas, nitrogen is dense
Degree varies less, therefore [N2] very little, [O in (3) formula are influenced on NO formation speed2] depend on combustion gas and air in combustion process
Equivalent proportion, so the temperature and equivalent proportion of combustion process are very big on the generation of NO influence, when ignition temperature is lower than 1500 degrees Celsius
When, T-NO production quantity is few, and when ignition temperature is higher than 1500 degrees Celsius, T-NO production quantity is significantly increased.The every increase of temperature
100K, NO formation speed about increase 5 times, and the production quantity of NO increases and proportional increase in excessive fuel with oxygen concentration.
Ignition temperature is equal near 1 in equivalent proportion there is maximum value, and corresponding NO speed also reaches maximum value.It is remote in excess air coefficient
When from 1, the formation speed of NO will be drastically reduced.The production quantity of NO increases with residence time of the flue gas in high-temperature region and is increased simultaneously
Greatly.In addition, the activation energy of reaction is reacted than combustible component in elemental oxygen and fuel due to (1) formula, that is, elemental oxygen O and nitrogen molecular N
Activation energy it is big, therefore the formation speed of NO is slower than combustion reaction, so a large amount of NO will not be generated in flame, the generation of NO
Journey is carried out in the rear end of flame zone, that is to say, that is largely generated in flame downstream.It is generated in conclusion influencing T-N0
Principal element be temperature, oxygen concentration and residence time.
