Device and method for fire coal management and combustion strategy optimization in variable coal quality conditions of coal-fired thermal power generating unit

Abstract

The invention relates to a device and method for fire coal management and combustion strategy optimization. At present, a device and method for fire coal management and combustion strategy optimization do not exist, wherein the device and method for fire coal management and combustion strategy optimization can effectively solve the safety problem caused by variable coal quality conditions to a unit. The device for fire coal management and combustion strategy optimization is characterized by comprising a coal quality on-line analysis device, a communication interface, a local monitoring device, a network optical fiber, a first real-time database interface, a real-time database server, a second real-time database interface and a fire coal management and combustion strategy optimization system server, wherein the coal quality on-line analysis device has the function of real-time and on-line measurement on the ash content, the moisture content and the heat quantity of coal, the coal quality on-line analysis device is connected with the local monitoring device through the communication interface, the local monitoring device is connected with the first real-time database interface, and the real-time database server is connected with the fire coal management and combustion strategy optimization system server. The device and method for fire coal management and combustion strategy optimization effectively solve the problem that economy and safety of the unit are reduced due to the fact that the running adjustment mode is poor when coal quality is variable.

Description

technical field [0001] The invention relates to a coal combustion management and combustion strategy optimization equipment and method, in particular to a coal combustion management and combustion strategy optimization equipment and method under the condition of variable coal quality of a coal-fired thermal power unit. Background technique [0002] With the official implementation of the separation of power plants and grids, the competition in the power market has become increasingly fierce, which requires power plants to save energy and reduce consumption and reduce power generation costs while ensuring safe operation. In the composition of power generation costs of power plants, fuel costs are the most important part, usually accounting for 70%. It should be noted that in the past due to tight power supply and low coal prices, my country's power plants generally did not pay enough attention to fuel (coal) management. In recent years, my country's electric power industry h...
