摘要
我国的天然气储量相对有限,并且远离需求中心;与国际水平相比,中国的天然气价格较高。为了使天然气得到合理有效的利用,应该提高能源的利用率。针对这种情况,提出了天然气热电冷总能系统的应用模式,并对不同模式所用的几种主要动力设备进行了比较,以燃气内燃机加余热型直燃机和燃气机热泵系统为例对联结方式进行了论述。最后对系统的特点以及在国内的发展和应用情况进行了介绍,并指出了在我国的发展前景。
The domestic reserves of natural gas are relatively limited and the gas fields are far away from the consumers. Moreover, the price of natural gas in China is relatively higher compared with the international level. It is therefore necessary to improve the efficiency of energy use by rational utilization of natural gas. In view of this situation, the application mode of the natural gas heating-cooling-power overall energy system is put forward in this paper. Several types of main power equipment for different application modes are compared. The coupling modes for the gas engine with direct burning engine and gas-engine heat pump are discussed. In addition, the characteristics, development and application of the overall energy system in China are presented, and the prospects for the application of the system are assessed.
