Steam and hot water in food businesses; It is the common energy source of processes such as cooking, heat treatment, drying, sterilization and cleaning. This need is met by liquid or gas fired boilers in many facilities; In facilities where fuel costs are decisive, adapting the existing boiler to solid fuel stands out as an economical option.

A pre-furnace is a water-cooled combustion chamber that allows a rotary grate solid fuel system to be added to existing steam boilers, regardless of their design. Its structure with curtain pipes withstands high temperatures and transfers a significant portion of the heat released directly to the boiler water. The rotary grate behind it ensures complete combustion of coal and biomass, offering high efficiency and low emissions. Although it is most commonly used in Scotch-type boilers in practice, it can also be adapted to different boiler types.
