Abstract: Provided are a standing coke-making furnace, a coke-making system and a method thereof.

Abstract: A compressed-air energy storage system of a constant-pressure full-capacity energy-release type, includes two or more liquid-gas coexisting containers, at least one of the two or more liquid-gas coexisting containers is filled with a pressurized liquid, the rest liquid-gas coexisting containers are configured to store a high-pressure air, and the two or more liquid-gas coexisting containers are in communication with each other. When the compressed-air energy storage system of the constant-pressure full-capacity energy-release type operates in an energy storage operating condition, the high-pressure air can be directly stored in the liquid-gas coexisting container without energy conversion loss. When the compressed-air energy storage system operates in an energy release operating condition, the pressurized liquid circulates in the liquid-gas coexisting containers storing the high-pressure air, to realize a constant-pressure full-capacity release of the high-pressure air.

Abstract: The gravity compressed air energy storage system includes: a shaft, into which a pressure-bearing cylinder is movably inserted; a locking component arranged at a top of the pressure-bearing cylinder to support the pressure-bearing cylinder on a ground at a top of the shaft through the locking component in case that the pressure-bearing cylinder is at a lowest limit position; a primary gravity block arranged above the locking component; a spherical connection component arranged and spherically connected between the primary gravity block and the locking component; in which a plurality of guide components are arranged around the primary gravity block; and a plurality of guide rails arranged on the ground and at a peripheral side of the primary gravity block; in which the plurality of guide rails cooperate with the plurality of guide components.
