Technical solution used by the above-mentioned technical problem that the application solves is:
A kind of burner hearth of low nitrogen condensation stainless steel hot homogeneous solution-type reactor, it is characterized in that the burner hearth is only made of two circle heat absorption walls,
Outer ring heat absorption wall is made of burner hearth spiral fin coil, and inner ring heat absorption wall is made of light pipe, and the burner hearth is to configure in the horizontal direction
Hollow cylinder.The design is so that common hearth wall is omitted in present patent application, and by two circles with good heat absorption capacity
The wall that absorbs heat is constituted, succinct efficient save space.
Burner hearth spiral fin coil two sides are folded edges, and two flangings have angle, and angle vertex is burner hearth center
Line.
The inner ring heat absorption wall is made of identical light pipe uniform ring around burner hearth center line, is had between the light pipe of arbitrary neighborhood
There is identical gap.
The outer ring heat absorption wall is made of identical burner hearth spiral fin coil uniform ring around burner hearth center line, arbitrary neighborhood
Gap having the same for flue gas circulation between burner hearth spiral fin coil.
The burner hearth spiral fin coil is made of stainless steel.
The light pipe is made of stainless steel.
The radiation energy that fuel combustion generates largely is absorbed by light pipe, and sub-fraction is inhaled by outer ring burner hearth spiral fin coil
It receives, meanwhile, spiral fin coil folded edges improve heat convection effect, therefore whole thermal energy absorptivity is high, furnace outlet cigarette
Very low, 110 DEG C of the general < of temperature.
Compared to the prior art, the application has the following advantages:
1, common hearth wall is omitted.
2, the size of burner hearth being made of heat absorption wall is sufficiently large, and residence time of the flue gas in burner hearth is long, so that CO content is low,
Big chamber design keeps temperature in burner hearth lower and uniform simultaneously, so that NOx content reduces.
3, burner hearth outer ring finned tube is folded edges, and the flue-gas temperature for flowing through the finned tube sharply declines, so that sealing plate
100 DEG C of the temperature < on surface, thus entire boiler is not required to thermal insulation material, the air interlayer between sealing plate and outsourcing can be kept the temperature
Layer.
4, heat exchange element and other structures part are all made of stainless steel making, and antiseptic property is good, long service life.
5, spiral fin coil fin is laminated structure, and when impurity is more in air or combustion gas, flue is also not easy to block.
