Auxiliary component of biomass gasification furnace

An auxiliary component of a biomass gasification furnace is provided with three pairs of storage containers and an active steam exhaust part, a lead screw on the active steam exhaust part is rotated and operated, and after combustion steam in the storage containers and the storage containers reaches a certain pressure intensity, a plastic sealing plug can be lifted to exhaust the steam, so that the combustion steam can be sequentially conveyed into the storage containers to be stored. The fuel gas in the three pairs of storage containers can be conveyed to a polymerization container used for conveying the fuel gas, the fuel gas is conveyed to equipment such as a natural gas pipeline communicated with the fuel gas conveying channel through the fuel gas conveying channel for further application, a funnel and an impurity conveying channel are arranged, and the lower portion of the impurity conveying channel is communicated with a bias channel. The closed hollow cylinder and the first linear driver are arranged o
