The invention refers to a steam boiler with forced flow, designed to supply technological steam to small and medium-size industrial consumers. According to the invention, the steam boiler with forced flow is made up of three modules: the lower body (A), the intermediary body (B) and the upper body (C), respectively. The lower body contains a furnace with a burner (1) and some elements for guiding the combustion air (2). The intermediary body is delimited by some jackets (3) and includes the lower part of an economiser (4) and the upper part of an evaporator (5). The upper body includes the upper part of an economiser (4), a flat coil (6) that connects the two, a steam superheater (7) and an inlet tube for the cooling air. The air circulates between the metal jackets (3) cooling the boiler and, at the same time, is preheated so that it can maintain the combustion.
