Analysis of the Solar Chemical Pump System and the Coal-Fired Heating System with the LCA Method

The aim of the study is to compare and analyze the differences between the theoretical solar chemical pump system and a coal-fired heating system,and to confirm the former's environmental-friendly characteristics and the feasibility of its spread.The cost of a solar chemical pump system and a coal-fired heating system is calculated theoretically under the same conditions,then the two systems are analyzed by the LCA method.It results in the schematics of the theoretical solar chemical pump system and the coal-fired heating system,as well as the cost comparison chart of two systems under the same conditions.The conclusion is that,on one hand,the early investment and energy cost of running the theoretical solar chemical pump system is much higher than the coal-fired heating system,while,on the other hand,the LCA analysis shows that the damage to the surrounding air in the theoretical system running period are lower than the coal-fired heating system.Therefore,the theoretical solar chemical pump system is a new kind of energy saving heating system,and the cutdown of the early investment of the theoretical solar chemical pump system will benefit to its spread.
