At present in China the boiler combustion with natural gas model can not use energy according to the quality of energy, and strictly speaking, does not meet the requirements of energy conservation. So we must introduce the new mechanism to improve energy efficiency, and improve the status. In this paper, energy step utilization mode has been proposed based on characteristics of natural gas cool, heat and power cogeneration system, providing references to make full use of energy.%我国当前以锅炉燃烧为主的天然气利用模式不能按能量品质用能,严格来讲并不符合节能要求,必须引入新的运行机制来提高能源利用效率,同时改善现状[1].本文基于天然气冷热电三联产系统的特点提出能量阶梯式利用技术,为能源的充分利用提供借鉴.
