The prospect of distributed generation of gas engine

At present, China's energy and ecological problems are outstanding, the environmental carrying capacity has reached or close to the upper limit. According to the Research Report of the National Grid Energy Research Institute, China's 85% sulfur dioxide, nitrogen oxide, 70% of soot emissions from coal, petroleum based fossil energy burning, energy substitution has become a task of industrial production had to pay attention. In the generator industry is also the case, there is an alternative to the current coal, diesel power and other heavy pollution and low efficiency of power generation equipment, both to reduce pollutant emissions, but also a substantial increase in power generation efficiency, while reducing costs. In the recently held the 14th China (Shanghai) international power equipment and power generation exhibition, China power network reporter booth at the Powerlink electrical equipment (Shanghai) Co., Ltd. (Powerlink) found the answer.

According to introduce Powerlink marketing career department general manager Peng Liping, compared to diesel generator, using gas generator has the advantages in three aspects, namely clean energy alternatives, improve energy efficiency, turning waste into treasure. Because the diesel is getting less and less, and the emission standards are becoming more and more strict, the market of gas generating units has been created. In addition, gas internal combustion engine or distributed energy generation is an important way of power generation, with wind, solar and other new energy sources, gas power generation is more stable, more flexible advantages. In 2014 the government introduced a number of policies for distributed energy generation, according to the role of natural gas generation in the power system and put into operation, the implementation of differentiated tariff mechanism to encourage natural gas distributed energy and power users to sign a contract. In the future, gas power generation, energy comprehensive utilization characteristics of high efficiency, low emission, start in life, will win more market opportunities. According to the introduction, the efficiency of the traditional diesel generator is about 30%, while the gas generating units of electricity efficiency of 38%-40%, if it is the combined use of heat and power, comprehensive utilization efficiency can reach 90%, the efficiency of this point, it is necessary to replace the diesel generator. Secondly, gas generator gas except for natural gas, including special gas, biogas, coal seam gas, landfill gas, sewage treatment gas, straw gas, these gases in the past often being discharged into the air. This is not only a waste of resources, but also to the atmospheric environment pollution, if exploited can not only obtain more profits, but also protect the environment, and truly realize the "waste to treasure". Peng Liping revealed that Powerlink company in terms of biogas power generation in early 2014 has abroad used unit 1000kW, is on the verge of in China to carry out a 6000kW alcohol factory of biogas power generation project, a 500kW farm biogas power generation project, the development of these projects will promote a number of special gas generator applications.

It is understood that natural gas power generation is the mainstream of the international power generation, and the current generation of natural gas in China accounted for less than 5% of total electricity generation, with the developed countries there is a considerable gap. According to Peng Liping analysis, before the use of natural gas power in the domestic use is not good, there are several resistance factors, mainly for: domestic technology is not mature, equipment more dependent on imports, high costs, maintenance difficult, and pure domestic product quality is not high, high gas prices, electricity and online hard to wait. He pointed out that before the power generator equipment technology is mainly controlled by Germany, equipment costs are very high, and the product delivery period plus the installation and commissioning for more than 9 months, if the equipment failure, the sale price will be high. Taking into account the generator's return on investment is quite long, the majority of enterprises have to give up the enthusiasm of the investment. Peng Liping to China electric power network reporter, PowerLink in line with the concept of providing customers with the highest cost-effective, product advantage lies in the intelligence and integration, the complexity of the operation of a simple, focused on a touch screen can be achieved, with remote operation and monitoring, to provide security for the protection.

At present, PowerLink products are mainly exported to more than 80%, dealers across more than 100 countries, with the distributed generation in the country's wide attention, Peng Liping said, PowerLink is also gradually concerned about the domestic market, with confidence in the next two to three years will be distributed to the gas turbine products sold to cities and applications in china.
