Biomass is the largest source of renewable energy with a share of 54 percent. Energy consumption from this source rose by 10 percent to 119 petajoules in 2020. This increase is largely due to the higher use of biomass in coalfired power stations. The consumption of biogas and solid and liquid biomass in industrial boilers also increased.

Abstract: The paper presents development and validation of coal mill model (including the action of classifier) to be used for improved coal mill control. The model is developed by using the mass and heat balance equations of the coal mill. Genetic Algorithm is used to estimate the unknown parameters that are used in the model validation.

The coal, which is pulverized in the mills, is transported and distributed by the primary gas through the millducts to the interior of the furnace. This is done with a double function: dry and enter the coal by different levels for optimizing the combustion in the sense that a complete combustion occurs with homogeneous heat fluxes to the walls.

This balance in the mill caused better combustion in the upper furnace while balanced mills made for a more balanced furnace. Optimized burner belt combustion contributed to lower LOI, slagging, fouling, and reduced spray flows. The next step in this plant is to upgrade the mill to improve coal fineness to 75% passing a 200mesh sieve.

Coal Fineness and Fuel Balance • As fineness increases (reduction in coal particle sizing), fuel balance improves. The finer the coal, the more the two phase mixture (coal and air) behaves like a fluid than a solid in suspension. • The more homogenous mixture of air and coal results in more even distribution between the separate burner ...

A typical coal heating value could be 10,000 Btu/lb. The net impact of a variance of 100 Btu/lb would be for this example 100 Btus/kw. A variance of 100 Btu/lb of the coal sample from the actual coal could easily occur. If the coal sampler has a relatively highspeed, minimill as a crusher, the coal may be getting dried.
