Utilize high temperature flue gas recovery waste heat to produce steam electric power's exhaust -heat boiler

Utilize high temperature flue gas recovery waste heat to produce steam electric power's exhaust -heat boiler, adopt the horizontal formula structure of single drum, flue gas inlet department sets up the membrane wall system, the membrane wall system passes through the high temperature over heater and low temperature superheater links to each other with evaporator tube bank, evaporator tube bank loops through high -temperature economizer, medium temperature economizer and low -level (stack -gas) economizer link to each other with the exhanst gas outlet, high -temperature economizer passes through the drum and links to each other with the membrane wall system, the membrane wall system includes the prepattern wall, back diaphragm type wall, side diaphragm type wall with advance mouth diaphragm type wall, connect a tedge between prepattern wall and the back diaphragm type wall. The utility model has the characteristics of compact structure, hot recovery efficiency are high, the operation is reliable, energy -concerving and environment -protective, the leakproofness is good, has thoroughly solved the boiler problem of leaking out, has improved boiler steam output greatly, and abundant recovery waste heat has reduced the cost of electricity -generating, has improved economic benefits, and the thermal efficiency is more than 86%, and the waste heat recovery that can be applied to trades such as carbon element, glass kiln, coking utilizes.
