Structure of heating surfaces in boiler furnace chamber with circulating fluid layer

摘要

The structure of the heating surfaces in the combustion chamber of a circulating boiler contains a combustion chamber (1) suspended for attachment to a fixed support structure (8) by means of suspension devices (4) and that combustion chamber is limited by a nozzle (3a),ceiling (3) and side walls (2),which have a structure formed from water pipes and which has been removed from the walls of the fire chamber by the entrance of cyclones. The heating surface structure contains at least one separate vertical unit of the surface formed from a panel of water pipes extending perpendicularly to the side wall (2) and in its immediate vicinity by hanging from the ceiling (3) of the boiler combustion chamber.
