Module boiler is by more boiler joint controls, has related parameter according to heat supply temperature curve set etc., and refer to
The boiler number of units that the automatic decision of outdoor temperature intelligence should start, stop transport, it is automatic to realize nearly unattended pattern.Module boiler has
There is the characteristics of following：1st, modularized design, simple in construction, flexible for installation, conveniently；2nd, long lifespan, maintenance are simple, durable in use；
3rd, control system is perfect, safe and reliable to operation；4th, cleaning, environmental protection, low noise；5th, efficient, energy-conservation, operating cost are low；6th, on demand
Heat supply, integrated heat efficiency are high, and the integrated heat efficiency of separate unit cauldron is that the integrated heat efficiency of 79%, two boiler is 85%, mould
The integrated heat efficiency of block boiler is 90%.
Burner is industrial oil fired boiler, the visual plant above gas fired-boiler, and it ensures fuel stabilization ignition
With the process such as the completely burned of fuel, therefore, to suppress NOx growing amount must just start with from burner.According to reduction NOx's
Combustion technology, low nitrogen oxide burner are roughly divided into following a few classes：1st, stage burning device：Designed according to fractional combustion principle
Stage burning device, make fuel and air segmenting mixed combustion, due to deviation theory equivalent proportion of burning, therefore NOx generation can be reduced.
2nd, from cyclic burner：A kind of is the pressure head using combustion air, and part combustion product gases are sucked back, into burner, with
Air mixed combustion.Due to flue gas recirculation, the thermal capacity of combustion product gases is big, and ignition temperature reduces, and NOx is reduced.Another kind is certainly
Body recycle burning device is that partial fume is entered recycling directly in burner, and adds combustion process, such a burner
Have and suppress nitrogen oxide and energy-conservation double effectses.3rd, flame type burner is split：Its principle is that a flame is divided into several small fires
Flame, because flammule area of dissipation is big, flame temperature is relatively low, makes that " thermal response NO " has declined.Shortened in addition, flame is small
Residence time of the gases such as oxygen, nitrogen in flame, to " thermal response NO " and " fuel NO " has obvious inhibitory action.This is several
Burner adapts to any kind of combustion chamber, but when being used on module boiler, compatible degree is relatively low, can not suppress from source
The generation of nitride, and need to be improved boiler body and boiler room arrangement, use relatively troublesome.
The content of the invention：
The purpose of this utility model, which is that, overcomes above-mentioned the deficiencies in the prior art, and provides a kind of module boiler
Special full premix low NO, the burner structure is simple, reasonable in design, combustion gas and air can be sufficiently mixed, the thermal efficiency
It is high, safe and reliable.
As above conceive, the technical solution of the utility model is：A kind of special full premix low NO of module boiler, including
Burner head and gaseous mixture pipeline, it is characterised in that：It is equipped with one layer of firing device and burner head outermost in burner head
Metal fibre interlacement layer, burner head install ion flame detector built with equal pressing plate on metal fibre interlacement layer；Gaseous mixture
Gas electromagnetic valve group and air pressure switch, gas electromagnetic valve are installed respectively at gas inlet and air inlet on pipeline
The input of group is connected with Gas Pipe, and output end is connected with the inlet end of gaseous mixture pipeline, air pressure switch control combustion gas electricity
Magnet valve group, security solenoid valve are ignited firing device, and ion flame detector is connected with the working electromagnet valve in gas electromagnetic valve group；
The inlet end installation blower fan of gaseous mixture pipeline, outlet side connects with the air admission hole of burner head.
Said burner head is rectangular box.
It is equipped with below above-mentioned metal fibre interlacement layer and is used for supporting metal fibre interlacement layer and to control burning fire hole
Liner plate.
The utility model belongs to rear premix burner, be different from the common sectional combustion of in the market, flue gas recirculation burning,
Split the low-NO_x combustion technologies such as flame, it is safe, inhibit the generation of nitride from source and boiler body need not be transformed
Arranged with boiler room, strong adaptability, easy care.The utility model is exclusively used in module boiler.
Brief description of the drawings：
Fig. 1 is front view of the present utility model；
Fig. 2 is top view of the present utility model；
Fig. 3 is the electric operation control circuit figure of blower fan；
Fig. 4 is the electric operation control circuit figure of combustion head.
Embodiment：
As shown in the figure：A kind of special full premix low NO of module boiler, including burner head 7 and gaseous mixture pipeline 3.
Equipped with one layer of firing device 10 and burner head outermost it is metal fibre interlacement layer 5 in burner head, the metal fibre interlacement
Layer top is equipped with ion flame detector 9, and bottom, which is equipped with, to be used for supporting metal fibre interlacement layer and to control burning fire hole
Liner plate 4, burner head is built with equal pressing plate 6.Combustion is installed respectively at gas inlet and air inlet on gaseous mixture pipeline
Gas solenoid valve block 2 and air pressure switch 8.The input of gas electromagnetic valve group is connected with Gas Pipe 11, output end and gaseous mixture
The inlet end connection of pipeline 3, air pressure switch control gas electromagnetic valve group, security solenoid valve ignite firing device, ion fire
Flame detector is connected with the working electromagnet valve in gas electromagnetic valve group；Gaseous mixture pipeline inlet end installation blower fan 1, outlet side with
The air admission hole connection of burner head 7.
The burner head is rectangular box.
Gaseous mixture after the gaseous mixture pipeline carries out combustion gas and air uniformly is sent into burner head；The blower fan is to use
To convey whole air needed for burning, it has a blast regulator, under the ratio of regulating gas and air together
Normal work, fan air inlet have an air filter to play dustproof effect；The air pressure switch is also a kind of blower fan
Protection device, when blower fan does not work or blast is inadequate, pressure switch does not work, to ensure magnetic valve in blast normal condition
It is lower just to work, ensure that burning is normal, while purging work before completion.
The working procedure of gas electromagnetic valve is：After switching on power, blower fan is started working, and air is sent into gaseous mixture pipeline,
After gaseous mixture pipeline has blast, air pressure switch, which is opened, gives security solenoid valve power transmission, and security solenoid valve is first lighted after opening to be drawn
Fiery device, then, ion flame detector detects flame to firing device point, and detection signal is transported into working electromagnet valve,
Working electromagnet valve is opened, while is sent into delivery of fuel gas in gaseous mixture pipeline, combustion gas after being mixed with the air that blower fan conveys
Burner head carries out normal work.
After the mixed gas of combustion gas and air (hereinafter referred to as mixed gas) enters burner head, carried out by equal pressing plate equal
Pressure, so that equalization of pressure of the mixed gas when overflowing liner plate and metal fibre interlacement in whole surface, makes in metallic fiber table
Burned flame is highly consistent on face.
