flue gas to stack 烟道气去烟囱
Gas from the combustion of fuel, the heating value of which has been substantially spent and which is, therefore, discarded to the flue or stack.
燃料燃烧产生的气体，其热值已大体上耗尽，因此排入烟道或烟囱。
Before entering the existing stack the flue gas has to be reheated to protect the stack against condensates. For reheating the gas gas Heater (GGH) is used.
因此在进入烟囱之前，必须被再度加热而使烟囱不结露，因此烟气换热器就被运用了。
Flush system with hydrogen until required purity is reached. Vent all waste hydrogen through a flue or flare stack.
用氢冲洗设备，直到达到所要求的纯度。通过烟道或火把烟筒排出所有废氢。
