Abstract

The utility model discloses a steam combustion-supporting boiler which comprises a boiler body and a fan. An air outlet of the fan is communicated with the inner portion of the boiler body, a steam combustion-supporting device which is communicated with the inner side of the boiler is further fixedly arranged on the outer side below the boiler body, and the air outlet of the fan is further communicated with the steam combustion-supporting device through an air pipe. By arranging a steam generator, steam produced by the fan is sent into the boiler body at a high speed, and the steam can stir gas inside the boiler to enable the gas inside the boiler to be fully mixed and achieve sufficient combustion. At the same time, particulate matter which is mixed in flue gas and not fully combusted becomes heavier when meeting the steam, and accordingly the particulate matter sinks to be combusted again. Therefore, carbon monoxide and smoke dust caused by insufficient combustion are prevented from being produced, environment is protected, and combustion efficiency is improved.
