Chinese engineer said the haze in Northern natural gas heating, experts do not agree-smog and air pollution-IT information
Hong Kong media said a retired senior Government engineer said, power plants using natural gas to generate electricity and household gas heating does not help to solve environmental problems, but will result in a haze. The engineer of the research results have been forwarded widely in the social media.
According to Hong Kong's South China Morning Post, December 28, 2016, the experts said, increasing the use of natural gas to cope with air pollution is correct, but need to install device can absorb moisture and water vapor produced by combustion of natural gas has played an important role in the formation of smog.
But the Ministry has questioned the results of the expert, said his conclusions are wrong.
On the occasion of this debate, earlier this month, most parts of North China are shrouded in thick smog, which is mainly caused by the power plant to power heating system in the winter.
MWR retired cadre, said senior engineer Li Chongxing, burning natural gas produces large amounts of water, the water vapor is mixed with the air pollutants in the smog would be generated. He estimated that Beijing every day burning natural gas produces only enough to fill a small reservoir of water vapour.
His study was published as early as 3 years ago, but in recent weeks was widely forwarded on the Internet.
Li Chongxing warned that government neglect dealing with water issues is likely to make a costly "coal to gas" project to no avail.
He said to the reporter: "the latest round of smog have confirmed my prediction. "He said:" if we are able to recycle water vapor gas boiler house chimney, we can not only reduce the harmful gas produced, and the principle of thermal cycle can also be used to improve the efficiency of the boiler room. ”
He said: "some universities have to upgrade their natural gas heating system. Regrettable is that the Government still turn a blind eye to this problem. ”
The Beijing Municipal Government said Beijing winter burn more than 1 million cubic meters of natural gas per day, in cities around the world, Beijing is second only to New York, the world's third largest natural gas consumption in Moscow city.
Li Chongxing said the high usage of natural gas means that one-third of humidity in the Beijing smog comes from the combustion of natural gas.
A few days ago, held a media Ministry of environmental protection, and invited several mainstream scientists. Their main point is that synthetic gas is only a small percentage of moisture in the atmosphere, probably only one of the hundreds of thousands of points. These experts believe that such a small percentage could not be the main cause of smog formation.
But Li Chongxing think artificial ratio of water vapour in the atmosphere in Beijing are likely to be far higher than the meteorologists estimate.
Germany marks-researcher at the Max Planck Institute for Earth, says Dr think Li Chongxing moisture leads to smog there under. He said: "the more moisture in the air, the more prone to chemical reactions. ”
But he did not agree with artificial moisture is a major cause of Beijing smog. He said, "compared to natural gas, synthetic gas is too small. Factory exhaust fumes and car exhaust are behind the haze of a murderer. ”
中国工程师称天然气采暖加剧北方雾霾，专家不认同 - 雾霾,空气污染 - IT资讯
港媒称，一名退休的资深政府工程师称，发电厂用天然气发电和住户用天然气采暖并未有助于解决环境问题，而是导致了雾霾。这位工程师的研究成果已在社交媒体上被广泛转发。
据香港《南华早报》网站2016年12月28日报道，这名专家称，增加天然气的使用以应对空气污染是正确的，但需要安装能吸收水气的设备，天然气燃烧产生的水气在雾霾的形成中发挥了重要的作用。
但环保部已对这位专家的研究成果提出质疑，称他的结论是错误的。
就在这场论战展开之际，本月早些时候，中国北方大部分地区都笼罩在厚厚的雾霾之中，这主要是由冬天电厂为供热系统供电所造成的。
水利部退休干部、高级工程师李崇兴称，燃烧天然气会产生大量水气，这些水气与空气中的污染物相混合就会产生雾霾。他估计，仅北京每天燃烧天然气产生的水气就足以填满一个小型蓄水库。
他的研究报告早在3年前就公布了，但最近几周才在互联网上被广泛转发。
李崇兴警告称，政府忽视处理水气问题很可能让耗资巨大的“煤转气”发电项目毫无成效。
他对本报记者说：“最新一轮的雾霾天气证实了我的预测。”他说：“如果我们能够回收天然气锅炉房烟囱排放的水气，我们不仅可以减少有害水气的产生，而且还可以利用热循环原理提高整个锅炉房的效率。”
他说：“一些大学已在对自己的天然气供热系统进行升级改进。令人遗憾的是，政府仍对这一问题视而不见。”
北京市政府称，冬季北京每天燃烧100多万立方米的天然气，在世界各大城市中，北京是仅次于纽约、莫斯科的世界第三大天然气用量城市。
李崇兴说，天然气的高利用率意味着，北京雾霾中三分之一的湿气来自于天然气燃烧。
日前，环保部举行了一场媒体会，并邀请几名主流科学家。他们的主要观点是，人造水气仅占大气层湿气的一小部分，很可能仅为几十万分之一。这些专家认为，如此小的比例不可能是雾霾形成的主要原因。
但李崇兴认为北京大气中人造水气的比例可能远远高于气象学者的估计。
德国马克斯-普朗克研究所研究员苏杭博士说，李崇兴认为水气导致雾霾的观点确实有根据。他说：“空气中含水量越多，就越容易产生化学反应。”
但他并不认同人造水气是造成北京雾霾主要原因的观点。他说：“相较于自然界产生的水气，人造水气的比例太小。工厂排放的废气和汽车产生的尾气是雾霾背后的真凶。”
