早在90年代初期，国外陶瓷窑炉界就开始重视陶瓷窑炉中排出的NOx的污染这个问题，并企图从燃烧方式着手解决这个问题。我国近年来也开始逐步重视，科技界已有人跟踪国外，试图用脉冲燃烧来解决它;但陶瓷窑炉NOx的严重排放，不仅仅是改进燃烧系统就可以得到解决的问题，我们也进行过测试，同一种窑型，烧成不同的产品，其烟气中的NOx的含量就不同，窑内烧成气氛(氧化或还原)其所排放的烟气中NOx含量亦不同，故陶瓷窑炉中NOx的产生是一个系统工程。由此看来，研究陶瓷窑炉中NOx的生成与破坏机理，并在其基础上提出经济上、技术上可行的综合治理方案已迫在眉睫。
燃烧矿物燃料如煤、原油、天然气等;生成氮氧化物污染有三种;即热力NOx，快速NOx，和燃料Nox[1～6]。
1. 热力N0x
关于热力NOx的生成机理是高温下空气的N2氧化形成NO;，其主成速度与燃烧温度有很大关系，当燃烧温度低于1400℃时热力NOx生成速度较慢，当温度高于1400℃反应明显加快，根据阿累尼乌斯定律，反应速度按指数规律增加。这说明，在实际炉内温度分别不均匀的情况下，局部高温的地方会生成很多的NOx;并会对整个炉内的NOx生成量起决定性影响。热力NOx的生成量则与空气过剩系数有很大关系，氧浓度增加，NOx生成量也增加。当出现15%的过量空气时，NOx生成量达到最大：当过量空气超过15%时。由于NOx被稀释，燃烧温度下降，反而会导致NOx生成减少。热力NOx的生成还与烟气在高温区的停留时间有关，停留时间越长，NOx越多。这是因为窑炉燃烧温度下，NOx的生成反应还未达到平衡，因而NOx的生成量将随烟气在高温区的停留时间增长而增加。至今认为研究得比较充分的是Zeldovick等人的生成理论，其主要反应如下：
2. 快速NOx
快速NOx是1971年Fenimore根据碳氢燃料预混火焰的轴向NOx分布实验结果提出的，是燃料在燃烧过程中碳氢化合物分解的中间产物N2反应生成的氮氧化合物，其生成速度极快，主要在火焰面上形成，且生成量较小，一般在5%以下，其主要反应如下：
在温度低于2000K(1727℃)时，NOx主成主要通过CH一N2反应;在不含氮的碳氢燃料低温燃烧时，需重点考虑快速NOX的生成。
3.燃料NOx
“燃料”NOx是由化学地结合在燃料中的杂环氮化物热分解，并与氧化合而生成的NOx，其生成量与燃料中氮的含量有很大关系，当燃烧中氮的含量超过0.1%时，结合在燃料的氮转化为NOx的量占主要地位，如煤的含氮量一般为0.5～2.5%;燃料NOx的形成可占生成总量的60%以上，燃料氮转化为NOx量主要取决于空气过剩系数，空气过剩系数降低，NOx的生成量也降低，这是因为在缺氧状态下，燃料中挥发出来的氮与碳、氢竞争不足的氧，由于氮缺乏竞争能力，而减少了NOx的形成。其主要反应途径如下。(1)氮化物大量转化为HCN和NH3，(2)HCN和NH3被氧化。反应方程如下：
国际上开展NOx生成机理及其控制的研究已有一二十年了。不过，目前关于燃烧过程中NOx生成的研究主要是以实验为主，还没形成完善的理论，如在煤粉燃烧领域内，主要是通过对具体过程进行实验研究与分析：希望找到一些规律，为解决实际问题提供依据、此外，从文献中也可以看到所有的研究都是公式少、实验曲线多、定量分析少而定性解释多的情况，这反映出NOX生成机理和控制是一个比较复杂、困难的领域，也是一个需要进行大量工作和大有可为的领域。特别对于陶瓷窑炉的NOX生成机理研究的报道不多，由其引起的环境污染也还没有引起足够的重视。
脱硝即脱出烟气中的氮氧化物，脱硝系统使用脱硝喷枪，喷射还原剂，还原氮氧化物为氮气和水，减少对大气的污染。
Laser cutting machines honeycomb
Why Laser Cutting Machines Honeycomb Makes a Difference
Anyone who has spent time around a laser cutter knows the challenges: heat buildup, smoke clouds, and fine debris that affect both the machine and the final part. That’s where the Laser cutting machines honeycomb table shows its real value.
The honeycomb structure works like a natural cooling system. Instead of letting heat collect under the sheet, the open cells allow air to flow and carry it away. This reduces the risk of material warping, especially when working on thin plates or jobs that demand tight tolerances. It keeps parts flatter and cuts more accurate.
At the same time, the Laser cutting machines honeycomb helps clear out smoke and dust. During cutting, fumes rise instantly and can interfere with the laser beam. The honeycomb channels guide them downward, away from the work surface. This means fewer burn marks, cleaner edges, and less rework after the job.
In daily use, operators quickly see the difference. Cuts look sharper, the working area stays clearer, and even the machine lens requires less cleaning. A simple Laser cutting machines honeycomb table ends up improving both product quality and the overall shop environment.
In short, it may look like just a support, but the Laser cutting machines honeycomb is one of those details that keeps the entire cutting process running smoother, cleaner, and more reliable.

Laser cutting machines honeycomb
Why Laser Cutting Machines Honeycomb Tables Make Cooling and Fume Control Easier
Anyone who has spent time around laser cutting knows two things always show up: heat and smoke. The laser beam generates a lot of heat, and the process throws off fumes and fine debris. If you don’t deal with these properly, you’ll end up with warped parts, dirty surfaces, and sometimes even a clogged machine. That’s why the Laser cutting machines honeycomb table is more than just a support—it’s part of what makes the whole system work smoothly.
The honeycomb design helps with cooling right away. Instead of holding the workpiece on a solid plate where heat builds up, the open honeycomb structure lets air move around the cut. The heat escapes through those tiny cells, so the underside of the material doesn’t burn or deform. In practice, that means straighter edges, less rework, and more reliable accuracy from one cut to the next.
Smoke and dust are another big issue. As soon as the laser cuts, fumes rise fast and can hang over the workpiece. If that smoke stays, it stains the material and can even bend the laser beam slightly, leaving a poor finish. The Laser cutting machines honeycomb table gives the smoke a way out—it flows down through the cells, pulling debris away from the cutting area. That keeps the beam clean and the surface clear.
The difference is obvious once you’ve seen both setups. Without a honeycomb table, you spend more time cleaning up burnt edges, dealing with uneven cuts, and wiping smoke marks. With the Laser cutting machines honeycomb design, the cuts come out sharper, the shop stays cleaner, and the machine itself doesn’t suffer as much wear.
In the end, that simple honeycomb isn’t just about holding the workpiece steady. It keeps the process cooler, clears out the fumes, and makes sure the final part looks the way it should. For anyone running laser cutting machines, the honeycomb table is one of those small details that quietly makes a big difference every day.
随着我国经济技术的发展和对环保要求的提高，能源的有效合理利用及燃烧污染物的排放控制正受到越来越多的关注与研究。为保护环境，减少二氧化硫和氮氧化物的排放，凡是有燃煤锅炉的企业，都需要用到脱硝技术。因此，脱硝喷枪也得到了广泛应用。但是，很多使用脱硝喷枪的企业经常遇到喷枪被磨损烧坏的现象。
为什么脱硝喷枪容易被烧坏?
燃煤锅炉内部的温度高，内部充满了粉尘颗粒，并且这些颗粒都在高速的流动。在高温下，加上粉尘颗粒对喷嘴的磨损，脱硝喷枪就很容易被损坏。
针对这种情况，处于行业领先地位的河北诚誉喷雾技术有限公司研发的高效耐磨型脱硝喷枪，主要有以下几点优势：
1、新型高效耐磨型脱硝喷枪采用了高强度的耐磨合金，使用寿命是普通脱硝喷枪的5至6倍。
2、普通脱硝喷枪气、液是在喷嘴处混合形成雾化，喷嘴一旦被磨坏，喷枪就会失去雾化功能，这样，液体就不能雾化，当液体碰到锅炉内壁，就会导致锅炉浇注料损毁。河北诚誉喷雾技术有限公司生产的新型高效耐磨脱硝喷枪采用了枪体尾部雾化技术。通俗的说，就是气、液在喷枪的尾部已充分混合，即便喷嘴损坏，喷出的液体仍然能保持良好的雾化效果，不但对锅炉不会造成任何损害，依然能保持良好的脱硝效果。
3、脱硝喷枪一般采用气助式双流体喷枪，普通脱硝喷枪需要借助冷却风对枪体冷却保护，而空气压缩机耗电非常高，俗称电老虎。河北诚誉喷雾技术有限公司生产的新型高效耐磨脱硝喷枪不需要冷却风，既节省了电能，为企业节约了成本，又避免了空气进入锅炉内，二次产生氮氧化物。
经过河北诚誉环境工程有限公司改造后的新型高效耐磨脱硝喷枪，不仅优化了雾化效果，提高了脱硝效率，而且大幅度地延长了喷枪的使用寿命，为企业带来了可观的经济效益。
Waterproof Wire Quick Connectors
How Waterproof Wire Quick Connectors Make Smart Home Lighting Easier
Last weekend, I was setting up some outdoor smart lights for my garden. Running all the wires and making sure everything stayed dry can be tricky. That’s where waterproof wire quick connectors really saved the day.
With these connectors, hooking up LED strips and outdoor lights was super fast. No messing around with tiny screws or worrying about a loose connection. Just snap them together, and the connection is secure. The best part? They keep water, dust, and dirt out, so I didn’t have to stress about a sudden rain shower messing up the lights.
I also liked how much easier they made the whole setup. In a smart home system, you often have multiple lights or sensors all linked together. Using waterproof wire quick connectors meant I didn’t have to spend hours checking every joint. Everything snapped in place, and I knew it would stay connected for a long time.
Another thing I noticed is durability. Even after a few hours of handling and some light rain while working outside, the connectors stayed solid. The lights didn’t flicker, and all the automation features worked perfectly. These small connectors really do a big job keeping everything reliable.
In short, waterproof wire quick connectors are tiny but powerful. They make installing smart home lights faster, keep connections safe from the elements, and save you a lot of hassle. If you’re setting up outdoor lighting or any automated smart device, these connectors are a must-have.
12 Volt 2 Pin Waterproof Connectors
Maintenance Tips for 12 Volt 2 Pin Waterproof Connectors
If you’re using outdoor devices, you know how much 12 Volt 2 Pin Waterproof Connectors take a beating. Rain, mud, and sun can all affect them over time. A little maintenance goes a long way to keep them working and prevent headaches.
Start with a quick check. Look at the seals and the connector body. Even small cracks or dirt can let water sneak in, which might cause corrosion or shorts. Spotting issues early makes things much easier later.
Cleaning is simple but important. Wipe off mud, dust, or any residue around the connector. Make sure the O-ring or sealing part stays clear. Doing this keeps your 12 Volt 2 Pin Waterproof Connectors doing their job, keeping water out.
Don’t ignore worn parts. Seals and gaskets naturally age, especially if they’re out in the elements. Replacing them keeps the connector reliable and protects whatever it’s powering.
Finally, handle them carefully. Don’t twist wires too sharply, and make sure the connector is fully plugged in. Proper handling reduces stress on the seal and helps your 12 Volt 2 Pin Waterproof Connectors last longer.
Even small steps like checking, cleaning, and swapping worn seals can save a lot of trouble. With a bit of care, 12 Volt 2 Pin Waterproof Connectors will keep your outdoor devices running smoothly for years.
