The simulation of grate combustion process is an important part of the models of grate boilers combusting biomass, municipal solid waste or other fuels. This work reports the first phase of the development of a new software tool for the simulation of fixed fuel beds. The presented simulations are transient, with one space coordinate (height of the fixed bed). Description of the mathematical model and of its numerical implementation is provided. The model is applied to the drying of straw, which is frequently used as a biomass fuel and equally frequently studied by researchers. The new software tool is validated by data published by other authors. Solution procedure, convergence and stability are discussed and proposals for future developments are summarised.

Simulace roštového spalovacího procesu je důležitou součástí modelů roštových kotlů spalujících biomasu, komunální odpad či jiná paliva. Tato práce představuje první část vývoje nového softwarového nástroje pro simulace pevných loží paliva.
