Protected Supervised Control in Bioenergetic Devices

摘要

Current European Union environmental policy aims at larger utilization of renewable energy sources. This paper describes the targets of renewable energy policy in the Czech Republic. However, when operating bioenergetic devices we can be tackled by problems of a hidden increase in harmful emissions This increase is caused by gradual loss of the proper function of the control variable sensor. As will be shown, if the control variable sensor produces biased data, then there is a danger that undesirable harmful emissions, above all emissions of CO and NO_x, will increase and will remain unrecognized. This paper will show how a supervised control can improve the ecological operation of a device. As a specific example of a technical solution, experimental Verner biomass boiler equipped with an oxygen sensor is used.
