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.

Refractory and concrete shotcrete gunite machine Kuwait  is specially designed for spraying refractory materials. Equipped with ABB frequency converter, it could achieve variable output by adjust frequency converter. There is one set high pressure water pump inRefractory and concrete shotcrete gunite machine Kuwait, which will provide atomized high pressure water, and make water and materials fully mixed.

The mixture is thus blown out from individual chamber of the rotor into transport hoses. As the materials passes through the blower into the transport hoses, lower pressure air is added to enhance the continuous flow of the material in hoses. The hoses are equipped with the spraying nozzles assy at the end, into which the mixing water is fed at the same time to wet the transported mixture. The required wetting of the mixture is controlled with the supply cock.

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.
