Natural gas power display advantages, LNG construction machinery need to be promoted      

In recent years, LNG has been listed as the preferred fuel in many countries, and at an annual rate of about 12%, becoming one of the fastest growing energy industry in the world. Since the outbreak of large-scale air pollution in early 2013, the state has strongly called for the development of green energy conservation and environmental protection industry.

The main emissions of common diesel construction machinery and equipment are carbon monoxide and some nitrogen oxides, which belong to the main air pollutants; while LNG construction machinery equipment only emits carbon dioxide and water, and does not emit nitrogen oxides. According to statistics, LNG construction machinery and equipment can reduce 93% of carbon monoxide, 33% of nitrogen oxides and 50% of the active hydrocarbon gas emissions. Visible, large-scale use of LNG construction machinery products will play a crucial role in the prevention and control of air pollution and environmental protection in china.

According to Lin Tianliang, an associate professor of the school of mechanical and electrical engineering and automation of Huaqiao University, the emission of harmful gases from natural gas combustion is far below the national standard, and the amount of particulate emissions is very low. At the same time, the ignition point and explosion limit of LNG are much higher than that of gasoline, diesel oil and LPG (liquefied petroleum gas), and the safety performance is higher.

At the same time, the use cost of construction machinery and equipment has become an important condition for users to consider. It is learnt that LNG construction machinery and fuel engineering machinery and equipment operation efficiency is equivalent, the use of cost is 70% of diesel, energy saving 30%. This is also an important reason for the country to vigorously promote LNG.

At present, the price of LNG is only 60% - 75% of that of diesel, and it has a huge price advantage over gasoline, diesel and LPG. Hill reconstruction Machine Co., Ltd. deputy general manager Tang Xiangyang told reporters: "on the mountain reconstruction machine excavator, the same type of products, LNG excavator price is higher than ordinary diesel excavator, tens of thousands of dollars, but compared with the user can save the use of cost is very small.". For example, the mountain excavator GC378LNG excavator can save 40% on fuel costs."

Reporter noted that, although the traditional engineering machinery purchase cost is low, but compared to natural gas vehicles driving lower cost, longer mileage, double bottle can travel 900 km, three cylinders can travel more than 1300 kilometers. Each kilometer saves 1 yuan more than the average car, so it can recover the cost of purchasing more in one year. Moreover, the natural gas combustion is sufficient, no carbon deposition, can effectively extend the life of the engine, which also reduces the use cost of LNG construction machinery to a certain extent.

In addition, LNG construction machinery and equipment basically do not maintain, is also an important factor in the use of low cost. Fuel engineering machinery and equipment need regular maintenance, and each maintenance cost is not expensive, LNG construction machinery and equipment does not exist for oil, machine filter, lubricating oil and other issues.

LNG construction machinery should be popularized in large scale

With the increasing market access standards such as the United States, Japan and other countries, the majority of construction machinery enterprises in China are becoming more and more difficult because of the high energy consumption and high emission problems. In order to improve the competitiveness of products, but also in order to prevent environmental pollution, domestic construction machinery giants have been aiming at the LNG construction machinery industry, and its market development has begun to take shape.

Since 2009, XCMG boldly developed LNG technology and launched the first LNG loader LW500K-LNG in the world, which caused great social repercussions. So far, China's LNG construction machinery and mountain reconstruction machine R & D the world's first LNG excavator, ZOOMLION bridge 12F Dongfeng LNG chassis CLG862LNG type mixer, Liugong loaders, Revo LNG loader, Ling Yu LNG concrete mixer truck, 31 LNG mixer, LNG engineering machinery China has a strong lineup.

Last year, the State Council issued in its "opinions on speeding up the development of energy conservation and environmental protection industry" proposed that the average annual growth rate of China's energy conservation and environmental protection industry output value is more than 15%, and by 2015, the total output value will reach 4 trillion and 500 billion yuan, becoming a new pillar industry of the national economy. The development of environmental protection industry has risen to China's national strategy, which is in the rising development period of the LNG construction machinery industry, not only closely follow the trend, but also an important opportunity for its large-scale market promotion.

"LNG for construction machinery, it should be regarded as the use of new energy.". In the context of the government's increasing emphasis on environmental protection and customer demand, it will be one of the opportunities for Quanzhou construction machinery to enhance market competitiveness." Lai Deguang, head of the administrative department of the South Road Administration, said in an interview with reporters.

However, LNG construction machinery products are also faced with challenges in the process of popularization and application: the equipment is expensive, the purchase cost is high, and the filling network is few, etc. these factors limit the large-scale promotion of LNG construction machinery. Once the price of natural gas is fully increased, it will inevitably lead to the corresponding increase of the cost of LNG construction machinery and equipment, which will become a major obstacle in the development of LNG construction machinery industry.

In this regard, Lin pointed out: "Mr Tim Lui Tim Leung on energy supply, LNG diesel as convenient, need to relevant national policies and the promotion of the host manufacturers supporting. For example, in the construction machinery relatively concentrated area set up filling station, or the host Factory Distribution of a filling car, let customers avoid worries."

At the same time, how to LNG large scale construction machinery product to market, how to allow users to truly feel the LNG products of environmental protection, cost advantages, the need to continue running between the enterprise and the market, quickly follow the needs of the market, the government needs more support. Although the new energy construction machinery conforms to the national energy conservation and environmental protection policy, but there is no financial subsidy, which will have a great impact on the future development and sales. If the state provides policy subsidies, LNG construction machinery will become the first choice of users. Therefore, the industry appeal, from the governance haze, energy conservation and environmental protection perspective, new energy construction machinery should be encouraged to buy products, should be included in the new energy vehicle subsidies directory.

LNG launched a series of product engineering machinery enterprises, not only to lead the development of the industry, engineering machinery declared "gas" Chinese era coming, with its high reliability, high technology, energy saving and environmental protection products and better customer service service system has become the best choice for users.
