Abstract

In the present work, optimization of the fuel and air use was done around a tunnel kiln producing bricks with low calorific value coal as an additive. The objective function is the cost of fuels together with heat lost through the stack. The mass and energy balance computations to calculate the energy to be supplied by fuels, were computed based on the plant data. The process constraints are the energy to be supplied by the fuels, air required for complete combustion, the SO2 emission to the atmosphere, the relative humidity of the stack gases and the percentage of carbon in the brick body.
