Description

Biomass gasifier

The invention relates to a biomass gasification machine, in particular to a person who can easily adjust the output energy and can recycle the carbon residue.

In recent years, the exhaustion of natural energy has become a serious problem. All countries are committed to finding alternative energy sources. However, whether it is wind or solar energy, the effective energy is not good, but the problem is that the combustion of organic matter is cracked to produce flammable gases such as hydrocarbons. The most efficient choice, however, if organic combustion is not controlled under specific temperature and pressure conditions, the product often contains carbon dioxide, which is nothing more than an increase in the greenhouse effect.

Therefore, there is a device capable of burning and decomposing organic waste under specific conditions to produce a combustible gas as an energy source, as disclosed in the patent TW M382456, and even the patent CN 200920293178 discloses a plurality of blowers. In order to provide a sufficient and continuous source of air, however, in general, the blower is not on or off, and because of the different types of organic substances, the required air mixing ratio is different, so the conventional structure causes the output of flammable gas flow. The mixing ratio with air is uncontrollable. If the flammable gas is directly connected to the ignition device, the fire may be too large or too small and the combustion rate may be lowered, resulting in difficulty in use or waste of energy.
