An automated biomass distribution system employs an air-sweeping nozzle for evenly distributing biomass on a grate of an existing stoker boiler. Such an automated biomass distribution system includes a valve-controlled air pressure source that generates an air jet upstream of the existing stoker boiler and having a first travel path extended downstream towards the existing stoker boiler; an expansion duct in fluid communication with the valve-controlled air pressure source and disposed downstream therefrom; an air-sweeping nozzle in communication with the expansion duct and having a second travel path extended downstream from the expansion duct; and a biomass distributor having a passageway disposed at the second travel path. Advantageously, the air-sweeping nozzle is disposed at the passageway and downstream of the expansion duct. In this manner, the second travel path is disposed downstream from the first travel path.

An automatic feed mechanism for the pellet grill with a loudspeaker comprises a feed hopper for storing pellet fuel; a loudspeaker and control panel electrically connected to the loudspeaker are provided on both sides of the inner wall of the feed hopper respectively, and the control panel incorporates a Bluetooth transceiver module for connecting Bluetooth devices and playing music; a stove stand for burning pellet fuel is provided on one side of the feed hopper, and a temperature-sensing probe is provided for detecting the internal temperature within the pellet grill; an automatic feed mechanism is provided for delivering the pellet fuel from feed hopper to stove stand, with the control panel electrically connected to the temperature-sensing probe. The invention modifies the electronic components of the control panel and adds a loudspeaker for playing music, with simple and cost-effective structures for dual purposes, realizing economic benefits and broad application prospects.
