Embodiment 1

[0026] Please check figure 1 , a gas turbine combined system, including a gas turbine fueled by ammonia, a low-temperature recovery device 5 and a waste heat recovery device 7 . The gas turbine includes a liquid ammonia supply device 4 , a compressor 2 , a combustor 1 and a turbine 3 . The low temperature recovery device 5 is connected between the liquid ammonia supply device 4 and the combustion chamber 1, the liquid ammonia is changed into gaseous ammonia by the low temperature recovery device 5, and the gaseous ammonia is supplied into the combustion chamber 1, and the low temperature recovery device 5 recovers The cooling capacity of liquid ammonia gasification. The compressor 2 is connected to the combustor 1 to compress gas including air and supply it to the combustor 1 . The combustor 1 contains the mixed combustion of gaseous ammonia and air. The exhaust gas from the combustor 1 drives the turbine 3 to run and is discharged from the exhaust passage 6. The turbine 3 a...

Embodiment 2

[0030] Please check figure 2 , it differs from Embodiment 1 in that: the low-temperature recovery device 5 includes a heat exchange path through which the liquid ammonia changes from liquid ammonia to gaseous ammonia, and the heat exchange path recovers the cooling capacity of the vaporization of liquid ammonia . The heat exchange channel cooperates with the compressor 2 to cool the air through the heat exchange channel, and the cooled air enters the compressor 2 . Due to the high latent heat of vaporization of liquid ammonia (at -33.41°C and 101.325kPa, the latent heat of vaporization reaches 1371.18kJ / kg), the air temperature is lowered, a higher air compression ratio is obtained, and the air intake volume is increased. At the same time, the liquid ammonia vaporizes to absorb the heat generated by the blades of the compressor 2, thereby reducing the temperature of the blades.

Abstract

The invention discloses a combined system of a gas turbine. The combined system comprises the gas turbine, a low temperature recycling device and a waste heat recycling device, wherein the gas turbine comprises a liquid ammonia supply device, a compressor, a combustion chamber and a turbine; the liquid ammonia supply device supplies ammonia to the combustion chamber; the compressor compresses a gas containing air and supplies the gas containing air to the combustion chamber; the turbine is propelled to operate through exhaust generated from combustion of the combustion chamber; the low temperature recycling device is connected between the liquid ammonia supply device and the combustion chamber; liquid ammonia is changed into gaseous ammonia through the low temperature recycling device; the low temperature recycling device recycles cold energy of liquid ammonia gasification; introduced gaseous ammonia and the gas containing air burn in the combustion chamber; exhaust of the combustion chamber propels the turbine to operate and is discharged from an exhaust passage; and the waste heat recycling device is arranged on the exhaust passage and is used for collecting exhaust heat. The combined system has the advantages that power can be output, and exhaust waste heat and / or gasification latent heat generated by liquid ammonia gasification can be recycled for utilization.

Description

technical field [0001] The invention relates to a gas turbine system, in particular to a gas turbine combined system using ammonia as fuel. Background technique [0002] A gas turbine is a rotary power machine that uses continuously flowing gas as a working medium to convert heat energy into mechanical work. In the main process of air and gas, there is a gas turbine cycle consisting of three major components: air compressor, combustor and turbine, commonly known as a simple cycle. Most gas turbines use a simple cycle scheme. Because its structure is the simplest, and it can best reflect a series of advantages of gas turbines, such as small size, light weight, fast start-up, and no need for cooling water. [0003] my country is currently the country with the largest ammonia production and consumption in the world, accounting for about 1 / 3 of the world's total production. Therefore, my country has excellent conditions to gradually realize the transition from existing fossil ...
