The invention discloses a full-cold-charge blowing-in method for a fuming furnace with a waste heat boiler. The method includes the steps that high-pressure oxygen removing water is used for conducting water changing and heating of the waste heat boiler of the fuming furnace, and then firewood is used for ignition and warming; and then pulverized coal is used for heating and building a molten pool, and full-cold-charge blowing-in of the fuming furnace with the waste heat boiler is achieved. By means of the full-cold-charge blowing-in method, due to fact that the molten pool is built through the fuming furnace, meanwhile warming of the waste heat boiler is achieved, molten pool building blowing-in of the fuming furnace is achieved under the condition that safety is ensured, and full-cold-charge continuous production is facilitated. Molten pool building blowing-in of the fuming furnace is achieved, clinker is adopted as blowing-in raw materials, clinker slag types are good, clinker melting is fast, packages cannot be formed, and molten pool building is facilitated.
