[0038] Examples:
[0039] The catalyst entering temperature is 680℃;
[0040] The catalyst intake is 500T / h;
[0041] The catalyst outflow rate in the outer heat exchange zone is 300T / h;
[0042] The catalyst outflow rate in the inner heat exchange zone is 200T / h;
[0043] The temperature of the catalyst flowing out of the inner heat exchange zone is 600°C; the temperature of the catalyst flowing out of the outer heat exchange zone is 540°C;
[0044] Use water as cooling medium to produce 3.5MPa saturated steam; inlet water temperature is 190℃; water flow rate is 600T / h;
