I went to him just to feedwatertemperature was good.
我于是给他喂刚兑好的温开水。
2
The influence rule for feedwatertemperature, oxygen content, air leakage rate of air preheater and the total air to exhaust temperature were analyzed.
得到了给水温度、含氧量、空气预热器漏风系数、炉膛总风量的改变对排烟温度的影响分析；
3
It is indicated that the enhanced condensation heat transfer technology on vertical tubes, when applied to vertical utility heaters, can efficiently raise the feedwatertemperature and save energy.
