Abstract
The invention relates to a system and method for preparing high calorific value synthesis gas by calcium-based chemical chain gasification of carbon-containing fuels, including a reactor, a combustion device, a gasification device, a reversing valve, an intake pipe and an output pipe; the reactor The outer wall of the outer wall is provided with a first interface and a second interface up and down, a burner is arranged on the inner top, and a calcium-based adsorbent bed is arranged in the middle; one end of the combustion device is connected to the first joint of the reversing valve, and the other end is connected to the second joint. One port or one of the second ports; one end of the gasification device is connected to the second joint of the reversing valve, and the other end is connected to the second port or the other of the first port; the intake pipe is connected to the third joint of the reversing valve , the first valve and the first induced draft fan are arranged on the intake pipe, and the output pipe is connected to the fourth joint of the reversing valve; the first joint of the reversing valve is set opposite to the second joint, and its third joint is opposite to the fourth joint set up. The beneficial effects of the invention are: effectively reducing the abrasion loss of the calcium-based adsorbent and reducing the extremely difficult control of the fluidized state of the system.
Description
technical field [0001] The invention belongs to the technical field of high-efficiency conversion and utilization of carbon-containing fuels, and relates to a system and a gas production method for preparing high calorific value synthesis gas by calcium-based chemical chain gasification of carbon-containing fuels. Background technique [0002] Power generation technologies using natural gas as fuel, such as combined cycle power generation, combined heat and power generation, and natural gas distributed power generation facilities, have energy efficiency advantages over coal. Studies have shown that the thermal efficiency of large-scale combined cycle power plants using natural gas as raw material can be as high as 61%; in combined heat and power plants, natural gas conversion efficiency can exceed 80%; small-scale gas-fired internal combustion engines or aeroderivative gas turbines using natural gas as raw material for direct conversion The efficiency can reach 45%. This is...
