Burning furnace for water decomposition

The utility model relates to a burning furnace for water decomposition, which can decompose the water into the hydrogen and the oxygen for burning. The burning furnace for water decomposition comprises a steam generator, a decomposer, a spraying device, a furnace cellar, etc., and uses the waste heat to decompose the water into the mixture of the hydrogen and the oxygen and then burns the mixture with fuel sufficiently. The utility model has wide range of application, can be used for burning completely in the furnace cellar, such as the boiler, the glass melting furnace, the annealing furnace, the iron-smelting furnace, etc., which use the fuel, such as the coal, the coke, the kerosene, the diesel oil and the heavy oil, etc., and can save energy and protect the environment.
