Problems solved by technology

However, the large-scale gas-fired internal combustion engines or gas turbines used in the power generation of the distributed energy stations built in Beijing, Shanghai and other cities directly burn natural gas for power generation, and the power generation efficiency is only 35%-45%, and the energy utilization rate is not up to standard, resulting in energy waste.

Abstract

The invention discloses a distributed energy system based on chemical looping combustion. The system comprises an air reaction unit, a fuel reaction unit and a combined cooling heating and power unit;the air reaction unit is connected with the fuel reaction unit to form a loop, and the air reaction unit and the fuel reaction unit are both connected with the combined cooling heating and power unitto provide a heat source for the combined cooling heating and power unit. According to the invention, natural gas is completely oxidized through a chemical-looping combustion mode of the natural gas,the CO2 separation operation is simple and cheap, and the efficiency of methane chemical-looping combustion heat supply is higher than that of a direct combustion heat supply mode. Meanwhile, waste heat generated by chemical-looping combustion is used for providing a heat source for the combined cooling heating and power unit, power generation, heat supply and cold supply of the combined coolingheating and power unit are achieved, and therefore, the energy utilization rate of the distributed energy system based on chemical-looping combustion is increased.

Description

technical field [0001] The invention relates to the technical field of gas, in particular to a distributed energy system based on chemical chain combustion. Background technique [0002] Distributed energy sources (distributed energy sources) refers to the comprehensive utilization of energy systems distributed on the user side. The distributed energy supply system mostly uses clean energy such as natural gas. According to the principle of energy cascade utilization, high-grade energy is used for power generation, and low-grade energy is used for heating, cooling or dehumidification. While satisfying users’ various forms of energy consumption, the maximum The role of energy utilization efficiency and control of emission pollution. [0003] Natural gas is an internationally recognized high-quality clean energy that can be applied on a large scale. It is also the main energy source for the ongoing energy transformation with huge potential for future development. In 2011, fou...
