The fire hazard of furnace heating is the presence of high temperatures on the surface of the furnace elements (walls, pipes, pipes), which can be a source of ignition of combustible materials and combustible structures of buildings. The temperature on the surface of the elements of non-heat-intensive furnaces depends on the type of fuel burned, the furnace heating mode and can reach more than 600 °C.
The temperature in the fuel tank of heat-intensive furnaces can be more than 1000 °C, and in the smoke channel in the area of the floor overlap — 500°C. The degree of heating of the side surfaces and the furnace floor, as well as the smoke channels, depends on the wall thickness, the type and amount of fuel burned, and the duration of Gorenje.
Elements of furnaces heated to high temperatures can be a source of ignition of materials located in the room and construction structures that can be burned (walls, partitions, floors, roofs), if they are adjacent to the surfaces of furnaces or smoke channels.
