A hybrid‐combination of the Monte Carlo and zone methods [1] is based on the zone method and uses the Monte Carlo method to calculate direct radiative exchange areas. This approach is developed to analyze three‐dimensional radiative heat transfer with anisotropically scattering media. Special technique of the Monte Carlo method for slop walls is presented. The code is applied to two test cases. In the first test case the program is validated by simulating a rectangular enclosure, in which the computed temperatures and wall heat fluxes are compared with Hottel's zone method. In the second case the code is applied to a 100 MW pulverized coal‐fired utility boiler. The geometry is discretised on a Cartesian grid.
