FANS FOR COMBUSTION SYSTEMS & PROCESSES
Precise airflow and constant pressure with Forward curved centrifugal fans are key to the combustion process inside incinerators, boilers, ovens, furnaces, kilns and dryers. Providing a precise airflow under a reliable and constant pressure, speeds up the combustion process and ensures maximum efficiency. Process manufacturers and power plants are amongst the many industries that require combustion to burn oil, natural gases and several types of waste. It is important to select the correct combustion fan to suit your duties, to ensure the system is operating at its full potential. Airflow and pressure requirements for combustion system depends on the type of fuel used, the size and design of the system. Centrifugal supply air fans such as our robust and reliable GRE range manufactured by Ecofit, are the preferred choice for many of our customers looking to optimise combustion in their applications.
Combustion fans play the core role in incineration systems and biomass boilers by vacuuming air from the atmosphere and blowing it into the chamber to speed up the burning process. Fans provide stability and ease of control, ensuring a constant circulation of air for maximum combustion. This provides an efficient heat generation system whilst also reducing costs.
The Science of Combustion
Combustion is the scientific term for burning, and is essentially a high temperature, chemical chain reaction that produces fire and the release of energy. To achieve successful combustion the right amount of heat, oxygen and fuel are required, if one of these is removed the combustion can’t take place. Therefore, altering the amount of any one of the three can control the rate of combustion or completely stop the process all together. This is why air supply using an industrial fan is key to effective combustion.
Medical Waste Management
High temperature medical waste incinerators are key to the destruction of hazardous, pharmaceutical and hospital waste. Combustion is the most effective process to fully destroy waste that poses a health and environmental threat. Any materials that contain toxic substances or potentially carry fatal infectious diseases must be safely destroyed with immediate effect to prevent further breakout.
Human & Pet Cremation
The combustion of deceased bodies requires a fully contained system to prevent the release of any toxic or germane compounds being released to atmosphere. An efficient combustion system reaching a very high temperature can break down and fully destroy any harmful toxins present. Therefore specifying the correct fan for a cremation oven is vital for achieving sufficient combustion. Incomplete combustion poses the risk of the hazardous compounds being released. It is also important that emissions are at a minimum throughout the process to comply with legislation.
Residual & Municipal Waste
Waste to energy incineration systems are a sustainable option for reducing the amount of municipal waste ending up in landfill. The heat generated from combustion processes in these systems produce a renewable source of energy contributing to UK and global energy generation. Waste energy plants manage non-recyclable waste with this technology in aim of preventing any waste at all being disregarded in landfill.
Combustion in Wood Waste Disposal
Waste pellet wood from industry or waste wood from land can be used as fuel for biomass boilers to produce heating and hot water on the premises. Biomass boilers are connected to an existing heating system and can provide warm air, underfloor heating and heat via existing radiators.
Combustion in Disposal & Waste Management Processes
Combustion processes play a key role in waste management and meet the disposal needs of various applications. Efficient combustion processes can produce energy that can be reclaimed as heat or electricity and in return produce a sustainable and cost-effective waste management recycling system. Such technologies are often the preferred method of reducing waste that would otherwise add to the growing problem of landfill mass. It is often a more convenient and cost effective method to dispose of waste on site, especially in remote locations where it can be difficult and costly to rely on waste collections services.
Many power and manufacturing plants require combustion systems on site for convenience and to reduce costs. Businesses utilising combustible materials such as wood on a continuous production line may require constant waste disposal to maintain a safe working environment. For example the production of wood pallets creates large quantities of wood waste that needs to be disposed of quickly. Combustion waste engines allow for fast disposal and can help to reclaim a substantial amount of energy back into the business as heat. Combustion technology is widely used to safely destroy hazardous waste that poses a health or environmental risk such as medical waste. This type of waste is potentially contagious or containing toxic chemicals and needs to be fully destroyed to maintain biosafety.
Ensuring a system has the right amount of air input with a stable and consistent flow using forward curved fans will provide maximum combustion by providing one of the three components needed: oxygen. A lack of air flow makes for poor combustion, less energy production and potentially more emissions. Sooting and flame failures are clear signs of air issues as the flames will gradually go out without sufficient air intake which results in the production of soot.
