PRIMORSKAYA THERMAL POWER PLANT: CONSTRUCTION OF MODERN PULVERIZED COAL-FIRED BOILERS

摘要

The main design solutions for coal-fired boilers of the Primorskaya TPP under construction are described. Boilers E-240-13.8-560KT with a tangentially fired furnace were designed to burn Kuznetsk bituminous coal and operate as part of 65 MW units. Features of the design coals, main design solutions for coal pulverizing systems, design features of the boiler, and a low-NO~( x )combustion system are considered. The layout of the boiler and boiler auxiliaries in the main building of the power plant is presented. Particular attention is paid to the aspects of emission reduction and the environmental compatibility of the boiler. The main design solutions for the integrated dry bottom ash removal system that allow using resulting ash and slag materials as saleable by-products are described. The results of 3D-simulation of the burning processes and expected NO~( x )emissions and unburned carbon are given.
