Answer:

Gas boilers are more economical than other fuels. At present, commonly used refractories on boiler walls are:

Clay refractory bricks (use temperature 1350 ° C ~ 1400 ° C);

Lightweight clay refractory brick (use temperature 1150 ° C ~ 1400 ° C);

Red brick (using temperature 700 ° C);

Clay refractory clay/mortar (refractoriness 1750 ° C);

Refractory concrete/castable (refractoriness 900 ° C ~ 1350 ° C).

Insulation materials include diatomite brick, asbestos powder, vermiculite products, cement perlite, slag cotton, and the like.

The various mortars used for bricklaying are generally configured as ready-made materials by the refractory material factory, but they can also be prepared on-site.

Rongsheng Refractory Company can provide refractory brick materials, thermal insulation materials, and various mortars for gas boilers.
