摘　　要：本文描述了一个以上吸式生物质气化炉、生物质气燃烧器及蒸汽锅炉组成的一体化生物质能热转换系统的自适应智能控制方法。系统以PLC为工具,以锅炉出口蒸汽压力为控制参数,根据锅炉出口蒸汽压力的变化,自动调节气化炉的供料量与产气量,并随之调节燃烧器的空气供应量,最终实现随蒸汽压力的改变而自动调节锅炉供热量的目标。以生物质气化为基础的一体化供热及自适应智能控制系统已经在工业应用中得到可靠验证。This paper describes an intelligent adaptive control on an integrated biomass gasification energy thermal conversion system, which composed of updraft biomass gasifier, biomass gasified gas combustor and steam boiler. The controller takes PLC as a tool and output steam pressure of the boiler as control parameter. According to the variation of the output steam pressure of the boiler, the input biomass amount and the output gas produced by the gasifier are adjusted automatically. And the air supplied to the gas combustor is then adjusted as well. Therefore, the heat supplied to the boiler is adjusted finally. The intelligent adaptive control and the integrated biomass gasification energy thermal conversion system are verified in the industrial utilization.
