According to the
biomass high-temperature and high-pressure air-assisted crushing
combustion device, a material bin is of a membrane wall structure and is arranged at the front end of a fire grate, a feeding port is formed in the upper end of the material bin, a
combustion cavity is formed in the lower end of the material bin, and a fire outlet is formed in one side of the material bin; the bale breaking device is located on the upper portion in the
combustion cavity and composed of a plurality of bale breaking units, each bale breaking unit comprises a bale breaking rotary roller and a heat collection air distribution
pipe which are arranged in parallel in a spaced mode, an air duct is formed in each bale breaking rotary roller, and the heat collection air distribution pipes communicate with the bale breaking rotary rollers and the air bellow; the bale breaking rotating roller is provided with a hollow spine communicated with the bale breaking rotating roller to form a second air outlet, the heat collection air distribution
pipe is provided with a hollow short
pipe communicated with the heat collection air distribution pipe to form a first air outlet, and an air bellow is arranged below the stock bin and connected with a high-pressure bale breaking
air blower. Compared with the prior art, bundled
straw is easy to scatter and dry through two times of concentrated injection of high-temperature and high-pressure air, meanwhile, a combustion-supporting effect is achieved, the bag breaking difficulty is reduced, the burn-
off rate of fuel is increased, then the heat efficiency of the heat exchange device is improved, and the heat exchange device is suitable for industrial popularization.
