Original abstract

The article deals with the issue of the use and reliability of the standard thermal design calculation of grate combustion chambers of low-capacity local heat sources. This standard analytical calculation based on dimensionless characteristic numbers tends to fail when applied to smaller furnaces even though it yields good results for centralized sources of higher capacity. However, when designing low-capacity boilers, it is still appropriate and advantageous to use this standard (empirical-analytical) calculation, which is able to yield at least indicative results in an incomparably shorter time and with significantly lower costs than an alternative and demanding numerical analysis based on CFD (Computational Fluid Dynamics) analysis.
