Description
Technical field
The present invention relates to a kind of boilers.
Background technique
For producing hot water or steam, boiler is made of known boilers external shell, which forms water and heat room
And at inner containment fire-box (firebox), fire-box is heat exchange relationship with the water to be heated being contained in heating room.
Combustion chamber is formed in fire-box and accommodates the combustion head that can generate the burner of flame in fire-box.Correspondingly,
Combustion chamber is connected to multiple heat-exchange tubes, and heating room is flowed by the hot combustion gas that flame generates and passed through in heat-exchange tube,
So that hot combustion gas can heat the water being contained in heating room.
Heat-exchange tube merges in burning gases collecting chamber, heat-exchange tube from burning gases collecting chamber by exhaust pipe by
Outer discharge.
The burner used in the boiler as described above can be forced-draft type, also referred to as atomizer burner or ventilation
Burner, wherein the fan for being arranged in the outside of boiler and the upstream of burner pushes the oxidation air aspirated from external environment
(oxidizing air) and towards burner.
Known in above-mentioned boiler and another type of burner used at present is made of pre-mixed gas burner,
Pre-mixed gas burner is commonly referred to as premix burner, wherein fuel gas and oxidation air to exist in premix burner
Before the combustion reaction occurred in combustion head, it is completely mixed and being connected to the premixer of combustion head by means of fan,
The burning of the mixture of air and gas is completed without any auxiliary air.
One problem of known burner is to provide the best combustion of the mixture formed by oxidation air and fuel gas,
To reduce the formation of the NOx for the exhaust pipe for being subsequently conveyed to boiler.
The total NOx that can be detected at exhaust pipe is mainly made of hot NOx, and the generation of hot NOx is as there are nitrogen and oxygen
The temperature of the flame of molecule and increase, the molecule of nitrogen and oxygen is not directly involved in burning and may originate from being also from so-called
The molecule of the lesser degree of promotion NOx, nitrogen and oxygen depends on the stoichiometry of combustion process and comes from so-called fuel NO_x, combustion
Material NOx is formed as the nitrogen present in fuel.
In the case where the burner of forced-draft type, in order to reduce a possibility that NOx is generated and a kind of solution for applying
Scheme is to provide exhaust gas being recycled to exhaust pipe in burner itself, to reduce the adiabatic temperature of flame, this is because
The heat generated in combustion reaction is distributed with larger quantities.
In the burner of forced-draft type, it is necessary to combustion gas recirculation is adjusted using having the valve of automatic adjustment,
There is the valve of automatic adjustment to allow the power of parameter and flame of its aperture based on burning and can be changed for this, therefore burning gas temperature
Probe is required, it usually needs oxygen probe, and under any circumstance, it is required to the electronics dress that there is the aperture of adjustment valve
It sets, this is therefore with the complexity of construction aspect.
Premix burner is utilized by replacing realizing the supply of excessive oxidation air in ignition mixture at present
Inhibit hot NOx, however the significant reduction of this efficiency of combustion for inevitably causing boiler.
Summary of the invention
The purpose of the present invention is to provide one kind to improve background technique at one or more of above-mentioned aspect
Boiler.
It, can be without specific structure and construction complexity the object of the present invention is to provide one kind in the purpose
In the case where and without reduce efficiency in the case where ensure reduce NOx discharge boiler.
It is of the invention that another the goal is to provide one kind can be assigned in their operations by means of its particular configuration feature
It gives reliability and the maximum of safety guarantees.
A yet further object of the present invention is to provide a kind of easy management and the boiler without specific electron combustion control system.
It is of the invention that another the goal is to provide a kind of that the boiler of NOx emission is controlled without using automatic regulating valve.
A yet further object of the present invention be by for any existing scheme it is alternative in a manner of overcome background technique the shortcomings that.
It is of the invention another relatively easy to be arranged and be obtained with competitive cost the goal is to provide a kind of
