天然气发电机组是适应世界环保要求和市场新环境而开发的新型环保燃气发电机组。天然气发电机组主要分为两种，一种是燃气轮机，一种是燃气内燃机。燃气轮机功率比较大，主要用在大、中型电站，燃气内燃机功率比较小，主要用在小型的分布式电站，单机功率在10KW-1000KW。
Natural gas generator set is a new type of environmental protection gas generator set developed to meet the requirements of world environmental protection and new market environment. Natural gas generator sets are mainly divided into two types: gas turbine and gas internal combustion engine. The power of gas turbine is relatively large, which is mainly used in large and medium-sized power stations. The power of gas internal combustion engine is relatively small, which is mainly used in small distributed power stations. The single unit power is 10KW-1000KW.
天然气内燃发电机组是取代燃油、燃煤机组的新型绿色环保动力。充分利用各种天然气或有害气体作为燃料，变废为宝、运行安全方便，成本效益高，排放污染低，并适宜热、电联产等特点，市场前景十分广阔。
Natural gas internal combustion generator set is a new type of green power that replaces oil fired and coal-fired units. Make full use of all kinds of natural gas or harmful gas as fuel, turn waste into treasure, operate safely and conveniently, have high cost-effectiveness, low emission pollution, and are suitable for heat and electricity cogeneration. The market prospect is very broad.
我国的天然气资源十分丰富，相对于我国丰富的天然气储量，天然气在我国一次能源消费中所占比例显得太小，未来具有大幅的潜力。在油田、气田以及机场、酒店、医院等领域越来越多把天然气发电机作为必不可少的备用发电设备，在断电期间它们能提供可靠的电源供应。只要天然气不断供应，发电机就会不停的发电。停电的几秒钟内，只要启动设备，就会有电源供应，关闭开关供电即停止—不需要用户作任何额外工作。设备全绝缘，并符合排放标准。可以预计，随着天然气供应的愈加充足、供应范围的不断扩大，近几年天然气发电将会得到一个飞速的发展。
China is rich in natural gas resources. Compared with China's rich natural gas reserves, the proportion of natural gas in China's primary energy consumption is too small, and it has great potential in the future. In oil fields, gas fields, airports, hotels, hospitals and other fields, more and more natural gas generators are used as indispensable backup power generation equipment, which can provide reliable power supply during power failure. As long as the natural gas is continuously supplied, the generator will generate electricity continuously. Within a few seconds of power failure, as long as the equipment is started, there will be power supply, and power supply will stop when the switch is turned off - no additional work is required for users. The equipment is fully insulated and complies with emission standards. It can be predicted that with the increasing supply of natural gas and the expanding scope of supply, natural gas power generation will get a rapid development in recent years.
