Boilers with fixed (stationary) layer of catalyst

In the presented paper, the special features of boilers with fixed catalyst layer and the types of catalyst fixing are described. The model of blackbody and radiant heat transfer from it to the heat-absorbing surface of boiler is also presented. The meaning of Catalytic Heating Element (CHP) is introduced, and the corresponding CHP constructions were developed for it. They are intended for the different arrangements and applications. Many efforts were made on selecting the efficient catalyst. The specific power characteristics of some catalysts are compared. It is recommended to take into account the obtained results in designing the heat generators with fixed catalyst layer.
