Abstract：Combined with the status of coal blending and management in fire-power plant,the shortcomings and unfitable elements in fuel management were analyzed.A design of intelligent fuel management and real-time coal blending system based on non-silos in power plant was proposed.The results showed that the pretreatment ditch and precise location based on calorific value and sulfur were set.With online monitoring and control system,the coal blending could be adjusted evenly,the particle size was less than 10 mm,the sulfur and calorific value of coal boiler could meet the design requirements,and it ensured the effective control of pollutants and the stable combustion of the boiler.A real-time fuel management solution and multi-channel separating and conveying device and control system of closed type coal blending based on non-silos was proposed.The solution could maximally reduce production cost and coal consumption,improve fund utilization rate and realize intelligent management of fuel.
