| Abstract: | Aiming at problem of the Gas-Gas Heater(GGH) components frequently emphraxis of de?sulfurization system in two power generation units of Ningxia Maliantai Power Plant, analyzes the blow?ing and sweeping effect of the soot blower and the components of dirt sample, finds out the causation ofthe GGH heat exchanging components frequently emphraxis. By the methlds of augment demisting ar?ea and rejiggering medium of blowing ash reconstructs the GGH heat exchanging components. The re?constructing result shows that eliminates the fault of GGH heat exchanging components emphraxis, in?sures the safe and stabilization of desulfurization system. |
