Problems solved by technology

[0005] Because the solid-shaped biomass pellet fuel produced by the ring die pressing method has a high density and a dense interior, it has the characteristics of fire resistance and high energy density, and is suitable for use in industrial occasions such as factory combustion boilers; but in biomass pellet fuel With the increasing popularity of modern times, many rural households also use biomass pellet fuels for daily life in daily fires, cooking water, and coal-fired stoves for heating in winter. Conventional solid biomass pellet fuels have the following disadvantages: There are few gaps, insufficient oxygen supply; the initial combustion speed of fuel is slow, and the heat generation is slow

Abstract

The invention relates to a hollow biomass granular fuel forming machine. The forming machine comprises a shell, a feed inlet is disposed on the shell, a hollow shaft is installed at a central axis inthe shell, a spiral pushing blade is fixed to the periphery of the hollow shaft, and bearings at two ends of the hollow shaft are fixed to supports at the rear end and the front part of the shell respectively; a core rod is arranged at the outlet end of the shell, a fixed end of the core rod is fixedly connected to the supports, and the free end extends to a forming outlet. The prepared biomass granular fuel is in a round tube shape, and has the characteristics of easy combustion, high initial combustion speed and sufficient combustion.

Description

technical field [0001] The technical field of biomass particle fuel of the present invention is specifically a hollow biomass particle fuel molding machine. Background technique [0002] Biomass pellet fuel is a block-shaped environmentally friendly new energy produced by processing straw, straw, rice husk, peanut husk, corncob, camellia husk, cottonseed husk, etc., as well as "three leftovers". Biomass pellet fuel has won wide recognition for its unique advantages; compared with traditional fuels, it not only has economic advantages but also has environmental benefits, which fully meets the requirements of sustainable development. First of all, because the shape is granule, the volume is compressed, which saves storage space, is also convenient for transportation, and reduces transportation costs. Secondly, the combustion efficiency is high, it is easy to burn out, and the amount of residual carbon is small. Compared with coal, it has high volatile content and low ignitio...
