WASTE HEAT BOILER STRUCTURE ATTACHED TO WASTE THERMAL DECOMPOSING FURNACE

摘要

PROBLEM TO BE SOLVED: To regulate a steam temperature at a superheater outlet to a proper temperature lower than a maximum working temperature by a method wherein dampers are respectively arranged at the outlet of a bypass passage and an exhaust gas passage in which superheaters are disposed, and a flow rate of exhaust gas is regulated. ;SOLUTION: A partition wall 2-3 is arranged in the same direction as the inflow direction of combustion exhaust gas in parallel to superheaters in a combustion exhaust gas passage in which superheaters 3-1 and 3-2 are disposed. A bypass passage T3-1 is formed between the partition wall and a partition wall 2-2. Dampers 8-1 and 8-2 being respectively openable are then arranged at the outlet of the bypass passage T3-1 and the outlet of a combustion exhaust gas passage T3-2 in which the supporters 3-1 and 302 are disposed. Through the openings of the dampers 8-1 and 8-2, an amount of exhaust gas to each heat-exchanger is regulated.;COPYRIGHT: (C)1998,JPO
