| titleOfInvention | METHOD FOR STARTING UP A SULFURIC ACID SYSTEM |
| abstract | A method of starting a plant for manufacture of sulfuric acid by catalytic oxidation of SO2 to SO3 and absorption of the obtained SO3 in sulfuric acid comprises heating the plant using flue gases obtained from combusting the fuel gas or oil in a starting installation, wherein in the course of starting and keeping warm the starting installation, the air protecting the starting heat exchanger /3/ after passing through the heat exchanger is directed to the starting furnace /2/ as secondary air so as to obtain the required temperature of flue gases before the heat exchanger. The air prior to being introduced to the starting heat exchanger /3/ is pre-heated in the cooling jacket /14/ of the starting furnace /2/. The flue gases which leave the starting furnace /2/ after having been passed through the starting heat-exchanger /3/ are partly recycled to the starting furnace /2/. <IMAGE> |
