基于污染治理视角的洁净煤燃烧技术的经济效益和环境效益分析

我国煤炭的粗放式利用使得环境问题日益严重,本文基于污染治理视角,根据系统动力学理论,从洁净煤技术的经济和环境层面入手,引入污染气体治理投入、供电减排收益、供电节煤收益等新因素,建立以超超临界技术(USC)、整体煤气化联合循环发电技术(IGCC)为代表的洁净煤技术效益估算模型,依此计算普通火力发电技术和两种洁净煤技术的耗煤量和污染气体排放量,分析发现USC和IGCC具有显著的环境效益和社会效益,同时发现使用USC和IGCC能够降低污染气体治理投入,减少政府在环境治理方面的开支,长期来看具有可观的经济效益。

Analysis of economic and environmental benefits of clean coal technology in the perspective of the pollution control

At present,a variety of traditional energy is being used in China,such as coal,oil,natural gas,and coal is one of the main energy in China.However,the extensive use of coal causes increasingly serious environmental problems.In this paper,we analyze the economic and environmental benefits of clean coal technology with system dynamics theory by introducing new factors,such as “the pollution gas governance input”,“the supply reduction benefits”,“the power supply coal saving benefit”.We establish the benefits of clean coal technology with USC technology and IGCC technology as the representative of the estimation model,respectively by calculating the ordinary thermal power technology and two kinds of clean coal technology.According to the analyses,we find that USC technology and IGCC technology have significant environmental and social benefits.At the same time,we find that the use of USC technology and IGCC technology can reduce pollution of gas investment and the government’s spending on environmental governance,from a long-term point of view with considerable economic benefits.
