Combustible ice efficient combustion system

A combustible ice efficient combustion system, comprising a combustible ice storage unit and a combustion unit, the front end of a furnace of the combustion unit being provided with a combustor, and the rear end of the furnace of the combustion unit being connected with a flue gas main pipe for discharging a high-temperature flue gas, wherein:

• the combustor is provided with a first gaseous fuel inlet, a second gaseous fuel inlet, a combustion-supporting gas inlet and a flue gas outlet, the first gaseous fuel inlet is provided with a combustion nozzle, the combustion nozzle is provided with a first gas inlet, a second gas inlet, a third gas inlet and a mixed gas outlet, the first gas inlet is connected with the combustible ice storage unit through a high-pressure natural gas pipeline, the second gas inlet is connected with an air source, and the mixed gas outlet is connected with the first gaseous fuel inlet of the combustor;
• and
• the high-pressure natural gas pipeline is connected with a natural gas branch pipeline, the natural gas branch pipeline is provided with a gas turbine, the natural gas branch pipeline conveys a high-pressure natural gas accounting for 50% to 60% of the total amount of the high-pressure natural gas in pipeline to the gas turbine for electricity generation, the generated electric energy is stored in an electric energy storage device, and the high-pressure natural gas is depressurized by the gas turbine to become a low-pressure natural gas, which is conveyed to the second gaseous fuel inlet of the combustor through a low-pressure natural gas pipeline.
