  • Power Generation From Coal Mill Rejection Using Kalina Cycle

    running with pressurized bowl mill to pulverize the coal and daily about 40 ton of low-grade worst coal is rejected from coal mills. This study is carried out to quantify the additional electric power that can be generated from coal mills rejection efficiently by cou-pling Kalina cycle with 500 MW e coal-fired thermal power plant.

  • The Inferential predictive control method of coal mill

    Nov 29 2015 · Finally we take the estimation of coal outlet mass flow as the new controlled variable and use inferential predictive control method to solve the coal mill control problems. The simulation results show that the new control method can shorten the delay time of the coal preparation system and speed up the response of the boiler to AGC command.

  • Modelling of Vertical Spindle Mills in Coal Fired Power

    A mathematical model of a vertical spindle mill used in coal-fired power plant is presented. The model is developed based on a mill size mass balance (SMB) and mill global mass and energy balances. The model has been validated using data collected from a 660 MW unit during mill modelling field tests. The model can be used to perform mill dynamic performance studies design and evaluate new
