Coal-fired heat-transfer material heater with multilayer roof membrane tube

The utility model relates to a heat-transfer material heater, in particular to a coal-fired heat-transfer material heater with a multilayer roof membrane tube, and belongs to the technical field of boilers. The coal-fired heat-transfer material heater with the multilayer roof membrane tube comprises a heater body (1) in which a radiant heating surface (2) and a convection heating surface (3) are arranged. The roof tube (4) is arranged above the radiant heating surface (2), has a multilayer structure, and is made from a membrane tube. According to the coal-fired heat-transfer material heater with the multilayer roof membrane tube, the roof tube above the radiant heating surface has the multilayer structure, and is made from the membrane tube, so that a heat transfer area is enlarged, a heater roof can be prevented from being permanently damaged by the direct radiation of flame, the service life of the heat-transfer material heater is prolonged, and a good heat exchange effect is achieved.
