Fuzzy Logic Control of Vertical Spindle Mills

1995-12-1 · 2. Dynamic fuzzy models of mill We consider a multi-input multi-output coal pulveriser mathematical model. This coal pulveriser is a vertical spindle pulveriser mill which is widely used in coal-fired power stations. Coal is introduced into the mill via a central tube and distributed laterally out on to a horizontal circular grinding table.

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

Coal-mill optimisation in coal-fired power stations

2018-1-23 · The vertical spindle mill crushes coal by feeding it between a grinding roller and either a bowl, table or ring at the bottom. Coal enters via the coal feed and falls into the grinding zone, where it is crushed by the grinding wheels. Control systems

Modelling of vertical spindle mills. Part 2: Integrated

2015-3-1 · 1. Introduction. Mathematic modelling is an effective approach to predict, simulate and optimise an operational process. The literature,,,,,,,has reported significant attempts to model vertical spindle mills (VSM), which are dominant in pulverised fuel (PF) production in coal-fired power stations, and are also applied in the cement and mineral industries.

Mass flow and particle size monitoring of pulverised

The first step towards condition based maintenance of the milling plant is the implementation of on- line condition monitoring of the mill. The following paper pr esents and analyses methods of monitoring the key performance factors of a vertical spindle mill that is suited for implementation on older power stations, i.e. the quantity (mass flow rate) and quality (particle fineness) of the
