This valve must also have an hourly rated temperature steam BTU discharge capacity not less than the hourly input rating of the water heater.
这种阀门每小时排放高温蒸汽btu的能力必须超过热水器每小时产生热量的能力。
The boiler, the steam turbine and the pump work in rated capacity, thus all getting the highest electric generation efficiency.
锅炉、汽轮机都可以满负荷工作，得到最高的热效率。
