Businesses in the furnaces and burners category supply, install, maintain and repair equipment used to generate heat for industrial and commercial processes. Furnaces may be used for heat treatment, melting, drying, firing ceramics or processing materials, while burners provide controlled combustion of gas, oil or other fuels. Equipment ranges from individual burners and replacement components to complete furnace systems, ovens and kilns. Services can include assessing heating requirements, designing or modifying equipment, installation, commissioning and fault diagnosis. Routine work may involve cleaning, replacing parts, checking combustion and adjusting controls to support safe, reliable operation and efficient fuel use. Suppliers may also provide temperature controls, fans, valves and monitoring systems, as well as advice on fuel compatibility and maintenance schedules.
