开远小龙潭火电厂年排灰量约50×104t。由于粉煤灰中游离氧化钙（fCa0）和有害成份三氧化硫（S03）含量较高，因而在云南的坝工建设中一直得不到利用。

The annual flyash discharge from the Xiaolongtan Thermal Power Plant is about 500,000 t , which has not been utilized properly in construction of dams in Yunnan Province due to high content of free calcium oxide ( fCa0 ) and harmful sulfur trioxide ( S03 ) in it .

然后继续升温至800℃，反应0.5h，同时用浓硫酸吸收三氧化硫气体制取所需浓度的硫酸。

Then continue to heat up to 800 ℃, react 0.5h , and while absorb trioxide with concentrated sulfuric acid to produce the required concentration sulfuric acid .

工业上用三氧化硫（SO3）与水反应制备硫酸，如果超越了饱合点则会形成发烟硫酸，可用于制备某些有机试剂。

It is made industrially by dissolving sulfur trioxide ( SO3 ) in water , sometimes beyond the saturation point to make oleum ( fuming sulfuric acid ), used to make certain organic chemicals .
