Embodiment 2

[0042] Such as figure 1 as shown, figure 1 is a schematic diagram of a coal-fired power generation system with partial oxyfuel combustion combined with a calcium-based chemical chain. Such as figure 1 As shown, it uses a mixture of air, oxygen and recycled flue gas as a combustion aid, in which the mass flow rate of oxygen is 96.4kg / s, the volume of circulating flue gas is 616kg / s, and the proportion of flue gas circulation is 72%. The mass flow rate of air is 100.2kg / s, so that the boiler outlet flue gas CO 2 The gas concentration is increased to 45%, and the flue gas enters the calcium-based chemical loop post-combustion capture device for deep removal, CO 2 The capture efficiency increased to 97.6%.

Abstract

The invention discloses a power generation system with partial oxygen-enriched combustion combined with a calcium-based chain and a CO2 capturing method. Through a partial oxygen-enriched method in which a mixture of air, oxygen and recycled flue gas serves as a combustion improver, the CO2 gas concentration of flue gas of a boiler outlet is increased to 30%-60%, the flue gas enters a chemical chain combustion post-capturing device based on a calcium base, the calcium-based reactivity is greatly improved, the CO2 capturing efficiency reaches 95% or above, and the gross generation is increased.According to the power generation system, the oxygen generation cost, the carbon carrier cost, energy consumption and the CO2 capturing efficiency are all balanced, so that the comprehensive efficiency is the optimized, two advanced carbon capturing techniques of partial oxygen-enriched combustion and the calcium-based chemical chain are combined, and the power generation system and the CO2 capturing method have the advantages of good economical efficiency, simple process, low energy consumption, high carbon capturing efficiency and the like.

Description

technical field [0001] The invention relates to coal-fired power generation technology and power industry CO 2 Capture field, especially related to a coal-fired power generation system combined with calcium-based chemical chain and CO 2 capture method. Background technique [0002] CO in Earth's atmosphere since industrial civilization 2 The concentration has risen sharply due to human production activities. China has a large population, a relatively low level of economic development, and is in an important stage of accelerated industrialization and urbanization. CO 2 The control of China is facing great pressure and special difficulties. Electricity production is a centralized CO 2 Emission sources, control and mitigation of CO in electricity production 2 Emissions play an important role in solving the problem of greenhouse effect. According to the investigation of the United Nations Intergovernmental Panel on Climate Change (IPCC), the application of carbon capture ...
