| Biomass energy refers to the energy of the green plants stored in their own bodies through the process of absorbing carbon di oxide from the atmosphere by their own chloroplasts. As a kind of renewable ener gy, because of its unique advantages, it has become the focus of the world energy research.Biomass power generation is the main form of biomass energy application, and is a new kind of green power generation way. Biomass fuel has many kinds, combustion value in dry and wet state differences larger, high volatile fuel ignition temperature is low chlorine content is high, easy on the hearth corrosion characteristics. Because of these characteristics, if biomass is used as fuel, the problem of boiler selection is the problem of boiler selection.At present, the biomass fuel boiler has been studied, but there is no mature theory for the control of biomass boiler.75t/h water-cooled vibrating grate taking Donghai Longyuan biomass power generation com pany limited direct fired boiler as the research object. For biomass direct combustion control of the boiler with multi input multi output, nonlinear, time variable and multi variable coupling ch aracteristics, analyzes the combustion system in the control of dynamic characteristics, the relevant simulation. Also, designed according to the parent control switch the b iomass direct combustion boiler fuel, air flow, air guide and vibrating grate control system. Article finally from biomass direct combustion boiler combustion control system, operation adjustment, system optimization, etc. the pr eliminary research, through the analysis and research of boiler tem pering, a grate temperature over tem perature, furnace pressure cyclical fluctuations and the actu al operation and gives the optim ization scheme. |
