Biomass Heating : The Advantages of Wood Chip Fuelled Furnaces
As the world seeks to reduce its dependence on fossil fuels and mitigate the impacts of climate change , the use of renewable energy sources has become increasingly important . One such source is wood chips , which are a popular biomass fuel for use in heating systems , including furnaces . In this article , we will discuss the operation of wood chip fuelled furnaces .
Wood chips are small pieces of wood that are produced from a variety of sources , including sawmills , logging operations , and forest thinning projects . They are a renewable and sustainable fuel source , as they can be continually replenished through responsible forestry practices .
II. Wood Chip Fuelled Furnaces
Wood chip fuelled furnaces are a type of biomass heating system that use wood chips as their primary fuel source . They are commonly used in commercial and industrial settings , such as schools , hospitals , and factories . Wood chip fuelled furnaces are also increasingly being used in residential settings , particularly in rural areas where there is ready access to wood chips .
III. How do Wood Chip Fuelled Furnaces Work ?
Wood chip fuelled furnaces operate by burning wood chips to generate heat , which is then used to heat water or air . The heat generated by the burning wood chips is transferred to a heat exchanger , which is used to heat the water or air . The heated water or air is then circulated through a network of pipes or ducts to provide heating to the building .
The process of burning wood chips in a furnace is similar to the process of burning wood in a fireplace . However , in a furnace , the combustion process is carefully controlled to ensure efficient and clean burning . This is achieved through the use of a variety of technologies , including automated fuel feed systems , combustion control systems , and emissions control systems .
IV. Automated Fuel Feed Systems
Wood chip fuelled furnaces use automated fuel feed systems to deliver wood chips to the combustion chamber . These systems typically consist of a hopper , which holds the wood chips , and a conveyor or auger , which moves the wood chips from the hopper to the combustion chamber . The rate at which the wood chips are fed into the combustion chamber is controlled by a computerized system , which monitors the temperature and other variables to ensure optimal combustion efficiency .
Combustion control systems are used to control the combustion process and ensure that the wood chips are burned efficiently and cleanly . These systems typically consist of a computerized control unit , which monitors the temperature , oxygen levels , and other variables in the combustion chamber , and adjusts the amount of air and fuel being supplied to achieve optimal combustion efficiency .
Emissions control systems are used to reduce the amount of pollutants that are released into the atmosphere during the combustion process . These systems typically consist of a variety of technologies , including particulate filters , catalytic converters , and scrubbers , which remove pollutants from the exhaust gases before they are released into the atmosphere .
Wood chip fuelled furnaces are a renewable and sustainable heating option that offer a number of benefits over traditional fossil fuel heating systems . They are efficient , cost-effective , and can help to reduce greenhouse gas emissions . As such , they are an important tool in the fight against climate change , and their use is likely to continue to grow in the coming years .
