自2017年环保政策自施行以来，全国各地的企业可谓是“八仙过海，各显神通”，积极推进燃气锅炉低氮燃烧器改造。低氮锅炉的低氮排放，在众多低氮锅炉商品中锋芒毕露。

Since the implementation of the environmental protection policy in 2017, enterprises all over the country have been actively promoting the transformation of low-nitrogen burners for gas boilers. The low nitrogen emission of low nitrogen boilers has been exposed in many commercial products of low nitrogen boilers.

低氮锅炉改造依据炉膛尺寸能否达标可分爲以下两种方式：

According to whether the furnace size can meet the standard or not, the transformation of low-nitrogen boiler can be divided into the following two ways:

1、改换低氮熄灭器(全预混、烟气外循环、烟气内循环)

1. Replace the low-nitrogen extinguisher (full premixed, external circulation of flue gas, internal circulation of flue gas)

2、改换锅炉(冷凝锅炉、三回程燃气锅炉+低氮熄灭头)

2. Change the boiler (condensing boiler, three-return gas boiler + low nitrogen extinguisher)

由于冷凝炉更环保、更低氮，在锅炉低氮燃烧器改造中，选择改换冷凝锅炉已然成为一种必定趋向：

As the condensing furnace is more environmentally friendly and less nitrogen, it has become a certain trend to choose to replace the condensing boiler in the transformation of the boiler low-nitrogen burner:

（1）.超高效率：冷凝锅炉比普通锅炉效率高20%至30%,冷凝锅炉热效率可达108.9%。

 (1). ultra-high efficiency: the efficiency of condensing boiler is 20% to 30% higher than that of ordinary boiler, and the thermal efficiency of condensing boiler can reach 108.9%.

（2）.冷凝锅炉排烟温度低：排烟温度低至35℃。

 (2) condensing boiler exhaust smoke temperature is low: low exhaust temperature to 35 ℃.

（3）.供水温度可调范围大：冷凝锅炉自备世界上最先进的、质量最好的水温控制零碎及共同的构造和熄灭方式。

 (3) .wide range of water supply temperature adjustment: condensing boilers are equipped with the world's most advanced and quality water temperature control fragmentation and common structure and extinguishing methods.

（4）.愈加环保：冷凝锅炉氮氧化物(NOx)排放量只要30ppm，低于欧洲规范5级的56ppm。一氧化碳排放量大大低于普通锅炉排放规范。由于熄灭效率高，生成的二氧化碳远低于普通燃气锅炉。运转噪声小于40分贝。

(4) .more environmentally friendly: the NOx emission of condensing boilers is only 30ppm, lower than the 56ppm level of European code 5. The carbon monoxide emission is much lower than the normal boiler emission standard. Because of the high extinguishing efficiency, the carbon dioxide produced is much lower than that of ordinary gas boilers. The running noise is less than 40 decibels.

（5）.更平安：冷凝锅炉采用强迫循环，可以不熄灭室内空气(普通锅炉则必需熄灭室内空气，爲了平安需添加烟气报警零碎)。

 (5) safer: the condensing boiler adopts forced circulation and can not extinguish the indoor air (the ordinary boiler must extinguish the indoor air, and in order to be safe, the flue gas alarm shall be added to the fragmentary).

（6）.装置面积小：比传统锅炉占空中积小，大小节省锅炉房面积，1吨锅炉占空中积低至1.3㎡。

 (6). Plant area is small, compared to a traditional boiler of the air volume is small, the size of saving boiler room area, 1 ton of boiler air product as low as 1.3 ㎡.

（7）.区域供热控制零碎：提供完善的区域供热控制零碎，智能控制热网内各次要设备，合理运用整个区域供热，愈加节能。

 (7) regional heating control fragmentation: provide perfect regional heating control fragmentation, intelligent control of all secondary equipment in the heat network, reasonable use of regional heating, more energy saving.

（8）.冷凝锅炉采用共同的冷凝技术，最大限制应用熄灭发生的热能，运用先进技术将燃料与空气充沛混合，使燃料充沛熄灭，提供应锅炉充足的动力，同时将出口烟气中的热量最大化回收。

 (8). The condensing boiler using common condensation technology, maximum limit application out of heat, use advanced technology to mix fuel and air is abundant, the fuel abundant, should provide sufficient power boiler, and exports to maximize heat recovery of flue gas.

（9）.冷凝热水锅炉采用了最新理念的模块化设计方式，可依据用户的实践需求，提供各品种型不同规格型号的冷凝锅炉。

 (9) condensing hot water boiler adopts the latest concept of modular design, which can provide various types of condensing boilers of different specifications according to the practical needs of users.
