AREACH - Model 60*60 Cells -Mullite Blocks
Ceramic honeycomb blocks / re-circulation heat exchangers are widely used in the heaters and furnaces of many kinds ,widely used in petrochemical ,pharmaceutical, chemical, electric manufacturing, automobile and machinery manufacturing, metallurgical, paint, printing, paper, wood processing and others who needs to dispose exhaust gas. Extraordinary ability to withstand extreme thermal shock without breaking. Ceramic honeycombs have proven their value as the most efficient heat storage media for regenerative use. Besides,the block’s design allows straight-through, laminar gas flow with a low pressure drop that greatly reduces operating costs and the potential for plugging and maintenance problems. it theoretically provides a straight, aerodynamic channel for the air stream. Ceramics receives the heat coming from the treated emissions, is followed by the heating process.Most popular related searches
