biomass boiler refractory gunning machine

Refractory Gunning Machine is a special equipment used for repairing the refractory layer of high-temperature industrial equipment (such as boilers, chimneys, coke ovens, etc.). It uses high-pressure spraying to evenly cover the damaged surface with refractory materials (such as lime-based refractory mud) to form a new refractory layer. For the repair of lime-based refractory materials on boiler chimneys, it is necessary to select a gunning equipment suitable for lime-based materials.

Biomass boilers refractory gunning machine is a dry monolithic refractory designed for use with dry gun equipment. It usually includes additives to make it stickier. Gunite is applied by a special machine that uses compressed air to push the dry (or pre-dampened) gunite through a hose and to the target. Water (or additive) is added at the nozzle to moisten the dry mix so it sticks to the surface.
