The invention discloses a method for synergistic emission reduction by sintering of energy-carrying composite gas. The sintering material surface is sequentially divided into an ignition section, a heat preservation section, a middle section, a flue gas heating section and a machine tail section from the head to the tail of a sintering machine. According to the flue gas composition, temperature characteristics and heat demand in different sections, hot waste gas is introduced into the ignition section for ignition, hot waste gas is introduced into the heat preservation section and hydrogen-rich gas is injected in steps synchronously, and the middle section is coupled on the basis of injection of hydrogen-rich gas Water vapor is sprayed in steps to circulate the high-temperature flue gas in the tail section and the flue gas in the ignition section and / or heat preservation section to the heating section. After adopting the energy-carrying composite gas sintering collaborative emission reduction method, it can simultaneously achieve a greater reduction in the consumption of solid fossil fuels in the sintering process and inhibit the formation / decomposition of pollutants to generate pollutants. Compared with conventional air sintering, it can reduce CO emissions. 2 15~25%, CO40~50%, NO X 20-40%, SO X 5-20%, dioxin 50-80%.
