Power Generation

Enhance the power of your plants.

Mathios Refractories S.A. is truly the expert when it comes to refractory lining of coal production units. With over 50 years of experience in the Boiler and Power Generation industry, having performed more than 90% of the construction of new Power Plants in Greece and we own the exclusive maintenance of all PPC power plants of the country for more that 15 years.

Complimented with references in Balkans and the EPC construction of the Largest Hard Coal Power plant in Europe, Mathios quality of deliverables and customer satisfaction are second to none. Cutting edge formulations the strictest quality norms come together to produce the best possible solution to account for energy efficiency, reduced downtime, shorter repair cycles and enhanced productivity.

We are able to provide bricks, monolithic, precast sections as well as special parts. We have developed the hybrid lining system, combining the best of both brick and monolithic lining concepts to output the most time and cost efficient lining ever made.

Flue Gas Resuction Duct

Support Bracket Insulating Lining

Flue gas recirculation ducts use the combustion energy, which would otherwise be wasted, to dry and preheat the powdered coal. The ash content of the flue gases calls for high abrasion resistance refractories. The materials we produce have been successfully in service, for more than two decades, in all coal fired power plants across Greece. Apart from refractories, insulation materials are of high importance so as to minimize heat losses and reduce fuel consumption. This last goal is today more relevant than ever, as the need for environment conservation is becoming greater every day.

The refractory materials offered by MATHIOS REFRACTORIES are vastly tested and proven by the power generation industry around the world. Products from the following lines are recommended by our experts:

  • IDEAL: Alumina (Al2O3) bricks, with formulations based on calcined fireclay, are used as high abrasion refractory lining
  • MAT PLUS: Alumina (Al2O3) low cement castables (LCC), with formulations based on chamotte, sintered mullite and bauxite are used as high abrasion refractory lining
  • MAT PLUS MC: Alumina (Al2O3) medium cement castables (MCC), with formulations based on fireclay, are used as high abrasion refractory lining
  • MAT MICRON: Alumina (Al2O3) ultra-low cement castables (ULCC), with formulations based on bauxite, are used as high abrasion refractory lining
  • MAT LG: Alumina (Al2O3) low cement gunning materials (LCG), with formulations based on chamotte and bauxite, are used as refractory lining
  • MAT GS: Alumina (Al2O3) medium cement gunning materials (MCG), with formulations based on fireclay and bauxite are used as refractory lining
  • MAT G: Alumina (Al2O3) insulating gunning materials, with formulations based on expanded clay and vermiculite, for use as insulation linings
  • MATH: Insulation bricks, with formulations based on alumina and perlite, for use as insulation linings

Coal Mill Door

After leaving the ducts, the flue gas – coal mixture is lead to the mill where the coal gets pulverized. This highly abrasive two-phase stream  calls for high abrasion resistance refractories, especially at the impact zone. The materials we produce have been successfully in service, for more than two decades, in all coal fired power plants across Greece.

  • MAT PLUS: Alumina (Al2O3) low cement castables (LCC), with formulations based on fireclay, chamotte and bauxite are used as impact zone and general refractory lining
  • MAT PLUS MC: Alumina (Al2O3) medium cement castables (MCC), with formulations based on fireclay, are used as impact zone and general refractory lining
  • MAT MICRON: Alumina (Al2O3) ultra-low cement castables (ULCC), with formulations based on bauxite, are used as impact zone and general refractory lining
  • MATH: Insulation bricks, with formulations based on perlite, for use as insulation linings

Boiler Furnace Hopper

Refractory Lining

Ash left after coal burning, literally comes down as a shower on the boiler’s hopper. This highly abrasive shower dictates the use of very hard materials based on Silicon Carbide (SiC), in order to protect the boiler tubes.  The materials we produce have been successfully in service, for more than two decades, in all coal fired power plants across Greece.

  • MAT LG: Alumina (Al2O3) low cement gunning materials (LCG), with formulations based on silicon carbide, are used as refractory lining
  • MAT GUN: Alumina (Al2O3) medium cement gunning materials (MCG), with formulations based on silicon carbide, are used as refractory lining
  • MAT P: Alumina (Al2O3) patching materials, with formulations based on silicon carbide, are used as refractory lining

Refractory Lining of main Coal Burners
