Abstract
An intelligent boiler for burning biomass particles comprises a shell, a burner, a fuel box feeding component, a boiler body, an expansion water tank, a draft fan, a microcomputer controller, a motor and the like. The fuel box feeding component comprises a fuel feed box, a feed box cover, a helical feeding component, a rotary valve component, a preheating air distribution chamber component and a collecting pipe orifice. Fuels are stored in the feed box, and the controllable helical feeding component is mounted on the lower portion of the cavity of the feed box. When the boiler starts running, the fuels are helically delivered to the collecting pipe orifice and enter the rotary valve through a collecting pipe by the aid of gravity, and a rotary shaft of the rotary valve rotates to load the fuels into the burner. The helical feeding component, the rotary valve component and the motor constitute a linkage device by a chain, rotation speed of the linkage device is controlled by a program set by a microcomputer, and an automatic adjusting function of a heating furnace in a controllable state can be automatically adjusted. The rotary valve component is mounted on the lower side of the collecting pipe orifice and communicated with the burning chamber below through the collecting pipe, so that backfire is prevented.
