Steam generator

摘要

Embedded brown coal steam generator of forced-circulation type in which the combustion-chamber pipe wall in which flows the work means and the wall of pipes enclosing the flue gas stream for the secondary heating surfaces over the combustion chamber are of the pipe-rib-pipe formation where the pipe wall of the combustion chamber has openings to accommodate suction wells with view to intake part of the flue gas, said wells are supplied with pipings through whcich passes a work means forming the internal wall thereof, where they are positioned in series and towards the work means flow direction the combustion chamber wall formed by pipes, the water separator, the walls formed by pipes enclosing the flue gas stream and the internal walls formed of pipes of the single flue-gas suction wells towards the work means.
