 The principles and features of the present invention are described below in conjunction with the accompanying drawings, and examples are only used to explain the present invention, and are not intended to limit the scope of the present invention.
 Such as figure 1 and 2 As shown, a system for preparing high calorific value synthesis gas by calcium-based chemical looping gasification of carbon-containing fuels includes a reactor 1, a combustion device, a gasification device, a reversing valve 2, an inlet pipe 3 and an output pipe 4. The outer wall of the reactor 1 is provided with a first interface and a second interface up and down, a burner 5 is arranged on its inner top, and a calcium-based adsorbent bed 6 is arranged in the middle. One end of the combustion device is connected to the first joint of the reversing valve 2, and the other end is connected to one of the first port or the second port, and provides hot air or hot oxygen to the burner 5 , and then ...
