When it comes to producing power and heat, grasses, brush clippings, wood chips, logs, so on and so forth are renewable materials which are used as fuel, and one should remember that it was so long back that gasification boiler didn’t exist. There are pieces of evidence which prove that centuries back, wood in many forms as used for burning especially in caves so that they can warm up themselves before the usage of coal and other items. At the time of woodstove and fireplace, woods were used as a means to warm the whole house but as the time passed, traditional designs are now used as a form of culture and nostalgia rather than using it on daily basis. Wood gasification is now more common than ever before as it doesn’t need more wood for the thing to work efficiently which saves the trees from cutting down and in fact, helps the environment to protect the human race for a long run. Institutional boilers have come into place since the 19th century which has been advanced from that time and now, it’s new avatars can be found in the market.

There are many pros of wood gasification boiler such as the price of net fuel is less expensive than coal, natural gas or heating oil, woody biomass can be purchased and produced in the local areas which boost the local economies, and fuels like lumber yard waste, grasses, brush clippings, wood chips, logs are broadly sustainable, renewable and available. The prices of fuel are comparatively stable, pellet stoves are in comparison less polluting, the approval of the EPA (Environmental Protection Agency) can be found where the pellets are used in burning, as the technology is advancing, emission of few pollutants are found in wood-burning systems into the air than oil and coal.

Some of the notable cons are hazardous gases are released such as soot, carbon monoxide, and nitrogen oxide when a wood burns which is a huge factor to be worried about. In order to avoid pollution in a large scale, wood energy appliances like wood stoves, fireplaces, other wood energy appliances, etc. must be designed in such a way that air quality standards and regulations are met. To fill bulky fuel, wood systems are required to have more space and the sealed fireplaces and pellet stoves need both electricity and natural resource to support it which leads to wastage of both the source of energy that has a relation with wood gasification.
