Renovation for low NOx emission on one 600 MW tangential firing boiler is carried out in which the staged-air combustion technology is applied to reduce the NOx generation in the fuel combustion process inside the furnace. The performance of the boiler before and after the upgrading is compared and the results indicate that the NOx emission is reduced noticeably after the renovation. The actual operation also shows that the renovation has achieved the desired results.
