火电厂锅炉侧仿真与经济性预测

Simulation and Economic Forecast of Boiler Side in Thermal Power Plant

本文在Isdepci平台上通过C#语言搭建了一个火电厂锅炉侧热力系统仿真工程,该工程用模块化思想将锅炉划分为以下部分:炉膛、空气预热器、磨煤机、暖风器、风机、吸风口、省煤器、除尘器、脱硫塔、烟囱。每个模块不仅可以独立进行燃烧热力计算,计算结果也可以传递给其他模块进行迭代计算。模块化建模可以提高模型的通用性,通过增减不同模块对不同机组和不同工况进行建模,在利用实际电厂运行数据对模型的可靠性进行验证后,可以利用模型预测电厂节能改造后的各项运行数据。

This article builds a thermal power plant boiler-side thermal system simulation project on the platform called Isdepci through C# language. The project uses modularization ideas. We divide the boiler into the following parts: furnace, air preheater, coal mill, heater, fan, suction port, economizer, dust collector, desulfurization tower, chimney. Each module has the function of independent thermal calculation, and the calculation results can be passed to other modules for iterative calculations. Modular modeling can improve the versatility of the model. By adding or subtracting different modules to model different units and different working conditions, after verifying the reliability of the model with actual power plant operating data, the model can be used to predict the operating data of the power plant after energy-saving transformation.
