| Abstract: | For the purpose of recovering the heat contained in blast furnace gas of low beating value, a 75t/h pulverized coal boiler of the cogeneration power plant of Xiangtan Steel Co. has been retrofitted for burning blast furnace gas exclusively. Before that a retrofit project was put forth, following a preceding 3 dimensional digital heat transfer calculation for the interior of the boiler and an overall check of the thermal calculation. Ultimate on site test measurements showed that: using blast furnace gas exclusively, a boiler output of 78t/h can be attained with a boiler thermal efficiency more than 80% and a stack gas temperature below 180 °C . The superheater didn't show any sign of overheating, and the air fan output was able to satisfy requirements. The output attained eith mixed combustion of gas and coal was 88t/h. Thus, the expected aim of retrofit was arrived at. Figs 9, tables 7 and refs 5 |
