[accompanying drawing explanation]
Below in conjunction with the accompanying drawings this utility model is described further:
Fig. 1 is the structural representation of the boiler reducing emitting nitride in this utility model embodiment one;
Fig. 2 is the structural representation of the boiler reducing emitting nitride in this utility model embodiment two.
[detailed description of the invention]
Below in conjunction with the accompanying drawing of this utility model embodiment the technical scheme of this utility model embodiment explained and
Illustrate, but following embodiment is only preferred embodiment of the present utility model, and not all.Based on the embodiment in embodiment,
Those skilled in the art are obtained other embodiments on the premise of not making creative work, broadly fall into of the present utility model
Protection domain.
Embodiment one,
With reference to shown in Fig. 1, the boiler reducing emitting nitride in the present embodiment is vacuum or atmospheric hot-water boiler, and it includes
Boiler body 1 and combustor 2, be provided with burner hearth (not shown) in boiler body 1, burner hearth connects smoke pipe, smoke pipe and pot
Exhaust opening 4 on furnace body 1 connects, and is also loaded with liquid, in boiler body 1 as a example by water.
Being additionally provided with cooling heat exchanger 3 in burner hearth of the present utility model, boiler body 1 is externally provided with water inlet pipe 5 and outlet pipe 6,
Wherein be connected between the water inlet of cooling heat exchanger 3 with water inlet pipe 5 and have coolant circulation pump 7, the outlet of cooling heat exchanger 3 with go out
Water pipe 6 connects, and boiler body 1 is additionally provided with heat exchanger 8.
During work, combustor 2 produces flame in burner hearth and lights fuel, so that the water in boiler body 1 is heated, and hot water
Or cold water enters in cooling heat exchanger 3 from the cooled circulating pump of water inlet pipe 57, a part of heat produced during fuel combustion is cold
But the water in heat exchanger 3 absorbs, and thus causes the reduction of flame temperature.Containing nitride in the flue gas produced after fuel combustion
NOX, NOXFormed with oxygen combustion oxidation by nitrogen, and NOXGenerate and need higher reaction temperature, the most once flame temperature fall
Low, will be unable to meet NOXFormation condition, the nitride produced when decreasing fuel combustion, thus reduce in flue gas and nitrogenize
The content of thing, effectively protects natural environment, and the water heat absorption in cooling heat exchanger 3 flows in outlet pipe 6 after heating up.Due to burner hearth
In high temperature action, the water in boiler body 1 can absorb heat formation steam, and the water in water inlet pipe 5 also can be in inflow heat exchanger 8, this
Time heat exchanger 8 in cold water heat absorption, steam exothermic condensation formed water, and in heat exchanger 8 water heat absorption heat up and flow into outlet pipe 6
In.Achieve in this process and the exchange of extraneous heat, it is simple to the output of heat.
Embodiment two,
With reference to shown in Fig. 2, unlike embodiment one, the boiler in the present embodiment does not include heat exchanger, but includes
The nitrogen discharged boiler that reduces in water charging system, and the present embodiment is steam oven or steam generator, the boiler in the present embodiment
Body 1 is provided with evaporation mouth 15, and water charging system includes the first control valve 9 and the first check valve 10, and the first control valve 9 is connected to cold
But, between heat exchanger outlet 32 and outlet pipe 6, the first check valve 10 is connected between outlet pipe 6 and boiler body 1.
Additionally, the water charging system in the present embodiment also includes that softened water tank the 12, second control valve 11, small pump 13 and second are single
To valve 14, the second control valve 11 is connected between cooling heat exchanger outlet 32 and softened water tank 12, softened water tank 12 respectively with water inlet
