The turning turning smoke-box 9 of smoke-box 8, second of pipe 7, first forms.Flue 5, the first backhaul smoke pipe 6, the second backhaul smoke pipe 7 are in drum 1
Inside set gradually from down to up.The flow of flue gas route that burner 2 generates is the turning of flue 5, first smoke-box 8, the first return smoke
The turning of pipe 6, second smoke-box 9, the second backhaul smoke pipe 7, out of stock module 3, condenser 4, are finally discharged into air, such as arrow in Fig. 1
Shown in head.
Main problem is existing for the structure：The temperature of boiler combustion is usually at 2000 DEG C or more, and ignition temperature is once
The NO then generated higher than 1500 DEG CxContent is more, needs individually to be equipped with the out of stock processing of out of stock module progress, to reduce discharge flue gas
In nitrogen content, manufacturing cost is high；Out of stock module and condenser are located at outside drum, and occupied space is big, is not easy to install；It is limited to
The structure of single flue, boiler power are to be improved.
Utility model content
The utility model is intended to reduce the manufacturing cost of the low nitrogen boiler of three backhauls, reduces occupied space, reduces discharge flue gas
In nitrogen content, improve the power of boiler.
For this purpose, technical solution used by the utility model is：A kind of low nitrogen boiler of three backhaul of more flues, including drum,
Burner, condenser, and be arranged in drum flue, the first backhaul smoke pipe, the second backhaul smoke pipe, first turning smoke-box,
Second turning smoke-box, the flue are at least three, the burner using premix burner and equipped with flue quantity phase
Deng combustion head, each combustion head stretches into corresponding flue；In the drum third is provided at rearward position
It turns smoke-box, the flue gas that longitudinal baffle makes the second backhaul smoke pipe come out is provided in third turning smoke-box and is got on, get off progress
Flowing, the condenser are mounted on the back cavity of third turning smoke-box.
The smoke outlet communicated with the external world, third turning are provided at the top of the condenser as a preferred embodiment of the above solution,
The bottom of smoke-box is provided with " L " the type drainpipe communicated with the external world, and third turning smoke-box bottom is connected with " L " type drainpipe
It is minimum at position, occupied space is further saved, and condensed water is avoided to deposit.
Further, the rear of the second turning smoke-box is provided with manhole used for overhaul, facilitates personnel after drum
Side's disengaging, overhauls multiple flues.
The utility model has the beneficial effects that：Using multiple flues, premix burner is configured, thus by the temperature of combustion product gases
Degree control is at 1500 DEG C hereinafter, low-temperature burning NOxYield is few, it is no longer necessary to individually be equipped with out of stock module, reduce manufacturing cost；
Condenser is placed in drum, it is compact-sized, it occupies little space；Under same space, arrange that multiple flues compare single stove
Courage increases the power of boiler.
