Abstract

The invention discloses a solar-integrated coal based methanol synthesis and power generation co-production system, belongs to the field of coal grading utilization. The system mainly comprises threesubsystems of solar mass extraction, methanol synthesis and fired coal power generation. In the system, solar-driven coal mass extraction, methanol synthesis and fired coal power generation are coupled; tank and tower solar energy provides heat for pyrolysis and gasification of coals; and waste heat and wastes in the mass extraction and methanol synthesis process realize gradient recycling througha boiler and a steam-water system of a fired coal generator set. The system widens the utilization path of solar energy and realize coal based poly-generation through efficient system integrated coupling, meanwhile, is hopeful to reduce the fossi energy consumption, and improves the energy comprehensive utilization efficiency.

Description

technical field [0001] The invention belongs to the field of graded utilization of coal, in particular to a coal-based methanol synthesis and power generation co-production system integrating solar energy, in particular to an integrated power generation system for solar-assisted coal graded upgrading and methanol synthesis. Background technique [0002] Coal is the fossil energy with the largest storage volume in the world. The currently detected storage volume is about one trillion tons, which is almost three times the storage volume of oil. It is the guarantee of world energy security. However, in the process of coal utilization, problems such as low energy utilization efficiency and serious emission of carbon dioxide and pollutants often occur. With the increasing emphasis on energy security and environmental protection, efficient and clean utilization of coal resources is an important research direction at present. [0003] Coal indirect liquefaction technology is a cle...
