Switching 300 MW Power-Generating Units with Gas-and-Oil-Fired Boilers to Increased Load Mode

Abstract

The goal of the research is to develop the guidelines for increasing the capacity of the operating 300 MW power-generating units by using the allowances assumed at the design computations and manufacture of the power-generating equipment, while preserving its reliability criteria and performance efficiency. The capacity of the operating power-generating units is increased in three stages. During the first stage, the technical state and operation conditions are established, measures aimed at increasing the capacity and increased load capabilities and reasons that may restrict them, as well as modernization and reconditioning measures are determined. The second stage includes developing technical solutions and reconstruction measures to increase the transfer capacity of the systems. At the third stage, the study and testing of the power-generating units’ equipment in the wide load range, including overload modes, are carried out with assessing and comparing the reliability criteria and efficiency indices. Technical measures intended to upgrade and modernize the equipment are low-cost. Most of them consist in ensuring the normal operating state of the existing main and auxiliary equipment of the power generating units.
