Low nitrogen boiler: low nitrogen boiler is upgraded on the basis of common boiler shape, and the advantage of ordinary nitrogen boiler is low nitrogen oxide emission. The low nitrogen boiler is divided into two emission standards: a NOx emission below 80 mg, and another NOx emission below 30 mg. To achieve low nitrogen emissions, the use of low nitrogen burner must be satisfied. The new standard for the emission of air pollutants in the boiler of Beijing (DB11/139-2015), the "new standard" focuses on the restriction of the emission of nitrogen oxides from the boiler. In April 1, 2017, the new boiler performs a 30 mg / m3 emission limit, and the 80 mg / m3 emission limit is carried out for the boiler in the high polluting fuel prohibition zone. The height of the chimney with the capacity of 0.7MW and below should not be less than 8 meters, and the height of the chimney above the capacity of 0.7MW should not be less than 15 meters, and the limit value of the standard is close to the most stringent boiler emission standards in the world.
1, the low nitrogen boiler adopts three return structure, and the large volume design of the combustion chamber makes the combustion more full.
2. The structure of the wave furnace has increased the heat transfer area, and also satisfied the free expansion of the furnace after heated.
3. The threaded structure is adopted to strengthen the heat transfer effect.
4, the boiler adopts the wet back structure, the entire side butt butt weld, the reliability is high, the maintenance cost is low.
5, rear view device design, easy to observe the combustion state.
6, the design of over temperature, overpressure, water shortage, leak detection, flameout and other protective functions, boiler operation is safe and reliable.
7, boiler packaging has color plate, mirror stainless steel matte, stainless steel, beautiful appearance.
8, equipped with imported burners with good control performance to achieve full automation operation.
9. Low nitrogen boiler has high thermal efficiency, stable output and strong load adaptability.
