济南冷凝壁挂炉节能体现在哪些方面?

1、超低的烟气温度,要达到冷凝效果使烟气中的水蒸气变成水就要降低排烟温度,是其达到水蒸气的露点55℃温度,这样就大大降低了热量的损失这部分能量大概占到节能的30%左右。
Ultra-low flue gas temperature, to achieve the effect of condensation of water vapor in the flue gas into the water would reduce exhaust gas temperature, water vapor dew point is its reach 55 ℃temperature, thus greatly reducing the loss of heat in this part of the energy probably account for about 30% energy saving.  
2、采用全预混式燃烧,事先将空气和燃气充分配比以后再进行燃烧,这种燃烧是燃气具燃烧界中最顶级的一种燃烧方式,具体是燃烧速度快、火焰短,甚至无火焰、火焰温度高、燃烧充分、以及空气过剩系数小。
All-premixed combustion, prior to the ratio of air and gas fully burned later, this combustion is a combustion gas sector in the top of a combustion mode, specifically the burning speed, short flame, even without flame, high flame temperature, combustion, and excess air coefficient.  
3、 燃气燃烧是为了燃烧更加充分,实际空气供给量要大于所需要的空气量,如果供给量不足会造成燃烧不充分,浪费燃气。如果供给量过大,排烟量同时也会随之增大,进而带走大量的热量,也会造成浪费。全预混式燃烧的空气量可以自动调节,则可以控制在此范围内,这部分大概可能占节能总量的20%左右。
Gas combustion is to burn more fully, the actual amount of air supplied to the air more than the required amount, if supply shortage will cause incomplete combustion, waste gas. If the supply is too large, but also increases the amount of smoke, and then take away a lot of heat, can also cause waste. Premix combustion air volume can be adjusted automatically, you can control in this range, this part may probably account for about 20% of the total energy.
4、冷凝壁挂炉在设计时,一般采用全封闭燃烧,燃烧火焰周围全是热交换器,从而有效的降低了炉体自身的热量。而普通壁挂炉只有火焰上方有主热交换器,周围会造成热量损失。这部分大致可能占节能的20%左右。
Condensing boiler in the design, generally closed, the combustion flame all around the heat exchanger, thus effectively reducing the heat of the furnace itself. Only above the ordinary boiler flame has primary heat exchanger, heat loss around the cause. This part may be roughly accounted for about 20% energy saving.
