Detailed description of the invention
Fig. 1 is the agent structure schematic diagram of the utility model.
Specific embodiment
Further describe the utility model combined with specific embodiments below, the advantages of the utility model and feature will be with
Description and it is apparent.But examples are merely exemplary for these, does not constitute any restrictions to the scope of the utility model.
It will be understood by those skilled in the art that can be to the utility model skill under the spirit and scope without departing from the utility model
The details and form of art scheme are modified or are replaced, but these modifications and replacement each fall within the protection scope of the utility model
It is interior.
Referring to Fig. 1, the utility model relates to a kind of low-nitrogen discharged condensing steam boilers, including bracket 1, shell 2, pot body
13 and low NO 3, the bottom of the shell 2 be mounted on bracket 1, pot body 13 is installed in the inside of shell 2；Institute
The second flowing bundle 12, the first flowing bundle 10 and corrugated furnace combustion chamber 9 are sequentially installed in the pot body 13 stated from top to bottom, this
One flowing bundle 10 is parallel to each other horizontally disposed with the second flowing bundle 12, wherein the first flowing bundle 10 and the second flow tube
Front smoke box 4 communicates in pot body 13 with setting for one end of beam 12, the other end and the corrugated furnace combustion of first flowing bundle 10
It burns 9 outlet side of room to be connected to revolution smoke-box 11, the other end of the second flowing bundle 12 and the rear smoke box 15 being arranged in pot body 13
Connection；The flame-out port of the low NO 3 stretches in corrugated furnace combustion chamber 9；At the gas outlet of the rear smoke box 15
It is sequentially installed with interconnected condensation energy-saving device 16 and exhaust gases passes 17；It is equipped on the shell 2 and connects with pot body 13
Logical pressure gauge 6 (pressure gauge itself has pressure controller), stop valve 7 and safety valve 8, the pressure gauge 6, stop valve 7,
Safety valve 8, low NO 3 and condensation energy-saving device 16 access control cabinet.
It is the built-in explosion proof door of normally off when normal work is installed between the rear smoke box 15 and revolution smoke-box 11
