From plywood to plasterboard to concrete, building products are made with heat. Autoclaved aerated concrete (AAC) blocks cure in large steam autoclaves at 12–16 bar; precast elements gain early strength in low-pressure steam curing chambers; gypsum boards and veneers pass through long steam- or oil-heated dryers; plywood and laminate presses need platen temperatures of 160–220 °C, classic thermal-oil territory; asphalt plants keep bitumen liquid with hot-oil coils.
The fuel picture drives economics. These plants are usually outside city gas networks and consume heat around the clock, so coal- or biomass-fired equipment dominates: YLW thermal-oil heaters for presses and dryers, DZL/SZL steam boilers for autoclaves and curing. Wood-products factories in particular sit on their own fuel — sander dust, bark and trim burn happily in the same heater that presses the board.
Because product quality is set by temperature uniformity (a cold corner in a press means delaminated board), we pay special attention to oil-flow balancing and steam-header design when configuring equipment for this sector.
