Liquid or gaseous fossil fuel boiler for use in e.g. industry, has horizontal exchanger delimiting caudad combustion chamber, two lateral compartments and caudad axial compartment, where axial compartment is communicated with nozzle

摘要

The boiler has a bottom (2) emerged at an upper part through a nozzle (8), and a horizontal exchanger (4) comprising a set of nappes with an H-shaped profile comprising a set of lower nappes diverging downwards, where the lower nappes and upper nappes are adjacent to an internal wall of a cylindrical body (1). The horizontal exchanger delimits a caudad combustion chamber (5), two lateral compartments (6) and a caudad axial compartment (7), where the axial compartment is communicated with the nozzle.
