Zusammenfassung:	PURPOSE:To obtain a heater capable of heating in two or more temperature ranges, reduced in size, simplified in structure, and enhanced in heating efficiency. CONSTITUTION:A heater is composed of a cylindrical high-temperature heating furnace 10 and a low-temperature heating furnace 20 formed in a ring shape along the outer pheripheral surface of the furnace 10. A high-temperature release port 18 for releasing gas produced by heating liquid is provided in the high-temperature heating furnace 10. A liquid supply port 21 and a low-temperature release port 24 are provided in the low-temperature heating furnace 20. As a center wall between the high-temperature heating furnace 10 and the low-temperature heating furnace 20, a stainless steel-made cylindrical wail is provided. An introducing port 25 is formed in a lower part of the cylindrical wall on the opposite side to the supply port 21. A styrene monomer solution supplied from the supply port 21 is heated to a temperature of 180-250 deg.C inside the low-temperature heating furnace 20 to release a low-temperature distillate, thereafter being indroduced into the high-temperature heating furnace 10 through the introducing port 25 and heated to approximately 350 deg.C to release a high-temperature distillate.
