Abstract A chain boiler simulation software was developed with VC platform in order to choose the best adjust way to achieve efficient and safe operation of chain boiler under different working conditions. Focused on a 4 t/h coal-fired industrial chain boiler, mathematical models were established based on the mass conservation law, the energy conservation law and the heat transmission theory. The models consisted of 11 submodels, such as coal model, combustion model and furnace smoke temperature model. The models were used to analyze the operation parameters of chain boiler under typical working conditions. Results generally coincided with the data obtained by chain boiler thermodynamic calculation. Various boiler adjustment methods were forecasted after the changes of loads, coal types and air supply methods. As a result, the optimal adjustment method agrees well with the experience results. This software has been successfully applied in simulation platform as a demonstration, and it also can be used to guide, train and inspect the energy-saving operation of stoker personnels.

4 t/h燃煤工业链条炉模型及仿真调节
为了选择最优的调节方式,实现链条炉在变工况条件下的高效、安全运行,开发VC平台链条炉仿真软件.以4 t/h燃煤工业链条炉为研究对象,基于能量、质量守恒定律和传热理论建立数学模型,包括煤种模型、燃烧模型以及炉膛烟温模型等11个子模型.利用模型分析典型工况条件下链条炉的运行参数,模拟结果与链条炉热力计算得到的数据基本吻合.预测负荷、煤种以及送风方式变化后锅炉的各种调节方式,得出的最优调节方式与经验结果一致.该软件已成功在仿真平台上实现示范应用,可以用于指导、培训和考察司炉人员的节能操作.
