The invention refers to a steam and hot water generator designed to equip fixed or mobile thermal installations that supply industrial steam, warm or hot water at small outputs. The steam and hot water generator is made up of a first section (A) with connected coils, which is made of spiral tube, is shaped as an upside-down bell and is supported by inner ribs (23), a second section (B), also with connected coils, which forms a cylindrical shape and is located inside and in the immediate vicinity of a hearth jacket (12), a third section (C) with spaced-out coils, which forms a cylindrical shape and is placed in an annular space that is positioned in between the hearth jacket (12) and the body (1) of the generator, and a fourth section (D) with spaced-out coils, which makes a tapered shape. The top of the cone points towards the burner, so that a radiant-convective heat exchange takes place in the first section, a radiant heat exchange takes place in the second section, a counter-current convective heat exchange takes place in the third section, and the fourth section acts as a steam superheater.
