一、引言我厂1978年投产以来,厂内低压蒸汽过剩,其量随着季节差异而在10～20t/h之间变化。为提高企业经济效益,经过反复论证,确定利用这部分余汽驱动低品位热能汽轮机带循环水泵。 S1.3-3.6型低品位热能汽轮机由青岛汽轮机制造厂设计制造,其主要性能如下:主汽门前蒸汽压力 0.36MPa(绝)主汽门前蒸汽温度 180±5℃汽轮机排汽压力 0.013MPa(绝)减速装置出轴端输出功率 1300kW减速装置出轴端转速 660r/min汽轮机转速 3000r/min冷却水温 32℃
I. INTRODUCTION Since the factory was put into operation in 1978, the factory has a surplus of low-pressure steam and its volume varies from 10 to 20t / h with seasonal differences. To improve the economic efficiency of enterprises, after repeated demonstration, to determine the use of this part of the steam to drive low-grade steam turbine with circulating pump. S1.3-3.6 type low-grade thermal turbine designed and manufactured by Qingdao Steam Turbine Manufacturer, the main performance is as follows: Main steam front steam pressure 0.36MPa (Absolute) Main steam front steam temperature 180 ± 5 ℃ Turbine exhaust pressure 0.013MPa (Absolutely) Deceleration device Output power of shaft end 1300kW Speed reducer output shaft speed 660r / min Turbine speed 3000r / min Cooling water temperature 32 ℃
