鍋爐給煤與鼓風(fēng)模糊輔助決策方法

為提高鍋爐燃燒的熱效率，分析了燃燒過程中的給煤量與鼓風(fēng)量間的關(guān)系，提出了依靠
爐溫的變化信息判斷鍋爐的運行工況，進而對給煤量、鼓風(fēng)量進行相應(yīng)調(diào)節(jié)，確定最佳的風(fēng)煤比。給煤量及送風(fēng)量的動態(tài)調(diào)節(jié)系統(tǒng)的實現(xiàn)采用模糊決策方法，從而減小對系統(tǒng)頻繁調(diào)節(jié)造成的運行振蕩，使系統(tǒng)運行性能平穩(wěn)、自適應(yīng)性強。

Abstract: Analyses the relation of offering coal and wind during boiler running for improving the heat efficiency. Expounds the means of adjusting boiler running condition by the message of boiler temperature. Adjusts the amountment of coal and wind, confirms the best proportion of coal and wind. Accomplishing the variation adjust system for coal and wind with fuzzy decision can diminish running concussion because of adjusting frequently, insure the system run stability and adapt to transformation easily
Key Words: Boiler; Fuzzy control; Proportion of wing and coal; Auxiliary Decision
