In order to study the dynamic characteristics of the 660 MW ultrasupercritical circulating fluidized bed (CFB) boiler when the main fuel trip (MFT) and boiler trip (BT) are triggered, a dynamic simulation model of the 660 MW ultrasupercritical circulating fluidized bed boiler was established on the Apros simulation platform. The model dynamically simulated the MFT and BT processes at 100% ...
The 660 MW ultrasupercritical circulating fluidized bed (CFB) boiler, which is the maximum capacity and largest scale boiler in the world has entered construction stage in China. This study established a fullscale dynamic simulation model of the 660 MW ultrasupercritical at 100% boiler maximum continuous rating (BMCR) condition. The model consists of an airflue gas system, a watersteam ...
The coal mill trip is a potentially costly failure in the power plant operation that poses severe implications to the power complex's safe and continuous power generation. Coal mill trip causes a sharp decrease in the total coal flowrate, and under the improper operation control of the boiler, the performance of heating surfaces (superheater ...
Thermal efficiency is defined as the ratio of heat equivalent mechanical energy available at the turbine to the heat energy available at the combustion of coal in the boiler. The thermal efficiency of the thermal power plants is 30% approx. Most of the heat energy (approx. 50%) is wasted in the condenser.
The coalpulverizer is an important unit, which preprocesses coalfuel fed to the boiler in coalbased thermal power plants. It is extremely important to comprehend the operational behavior of the coal pulverizer unit for good performance of the boiler and overall coal powerplant.
