Innovative Technologies in the Repowering of the Nizhnekamsk CHPP by Upgrading the TGME-464 Boiler to Combust Pulverized Petroleum Coke

The repowering project of the Nizhnekamsk CHPP involves upgrading the main and accessory boiler equipment to allow flame combustion of pulverized petroleum coke (petcoke) produced by a TANEKO delayed coking unit. The scope of work includes equipping the gas-and-oil fired boiler with a burner arrangement for petcoke combustion and providing central coal pulverization and pneumatic ash handling. To meet the atmospheric emission requirements, it is necessary to equip the boilers with a selective catalytic reduction installation, high-efficiency electrostatic precipitators, and a desulfurization plant.
