How does gasification process work?
Gasification is a process that converts organic or fossil-based carbonaceous materials at high temperatures (>700°C), without combustion, with a controlled amount of oxygen and/or steam into carbon monoxide, hydrogen, and carbon dioxide.
Are gasifiers efficient?
For the entrained flow gasifier, the volatiles can be introduced into the hot product gas stream as a ‘chemical quench’. The overall efficiency of such a process scheme is comparable to direct gasification of wood, but more exergy is conserved in as chemical exergy in the product gas (72.6% versus 68.6%).
How does gasification help the environment?
Gasification plants produce significantly lower quantities of air pollutants. The process reduces the environmental impact of waste disposal because it allows for the use of waste products as a feedstock. Gasification plants also use less water than traditional coal-based power plants.
How does gasification work in a furnace?
By optimizing this process, gasification uses up to 95% of the fuel energy to provide heat where you need it. While all wood furnaces burn wood gases, a true gasification system uses a multi-stage downdraft process. This process allows you to control the air to fuel ratio for a cleaner, more efficient burn.
What is a gasifier?
Incredibly, World War II gasifiers powered tanks, cars, tractors – wherever petroleum was used – gasifiers were installed. These gasifiers lost a lot of heat, plugged up easily, and needed more manual tinkering. Today’s gasifiers are more efficient, better insulated, and use automated air mixture controls.

What is the difference between a wood furnace and gas furnace?
While all wood furnaces burn wood gases, a true gasification system uses a multi-stage downdraft process. This process allows you to control the air to fuel ratio for a cleaner, more efficient burn. Gasification works best with well-seasoned wood.
Are gasifiers more efficient today?
These gasifiers lost a lot of heat, plugged up easily, and needed more manual tinkering. Today’s gasifiers are more efficient, better insulated, and use automated air mixture controls. How Does Gasification Work?
