Abstract
The utility model relates to an energy saving and emission reduction vertical fire tube boiler using water as an oxidizing agent. The vertical fire tube boiler adopts a mode that multi-water jackets (water containers) are connected in series and the vertical fire tube is used for heating, water is adopted as the oxidizing agent, and high burning rate and little oxygen amount consumption are realized, thereby improving the heat exchanging effect, increasing the heat efficiency and saving energy sources. The combustion principle of the vertical fire tube boiler is as follows: hydrogen and carbon can be regarded as energy carriers; and energy can be transferred between hydrogen and carbon. Oxygen abstraction reaction occurs between a carbon or hydrocarbon compound and water in a high temperature environment, namely, high temperature steam is used as oxidizing agent which is subjected to a thermochemistry reaction with the carbon or hydrocarbon compound to generate oxygen-enriched gas. Water absorbs energy during decomposition; and carbon releases energy during oxidation; and energy is converted between the carbon and hydrogen. The High temperature environment is needed when the carbon and the hydrogen are subjected to the energy conversion; and the energy consumption is only used for maintaining the high temperature environment required by the thermochemistry reaction. Therefore, the vertical fire tube boiler not only can realize coal smokeless combustion but is also suitable for biomass fuels with high moisture content, household garbage and agricultural and industrial combustible wastes to be used as energy sources.
