A well designed and operated biomass boiler burning fuel within the specification of the boiler should not produce any smoke, but black smoke may be produced if the fuel is too wet for the boiler. All biomass boilers produce some oxides of nitrogen (NOx), particularly nitrogen dioxide (NO2). While NOx emissions from gas boilers have been reduced significantly in recent years through the use of low NOx burners which burn at a temperature slightly below that at which NOx forms, the nature of biomass combustion, and the need to ensure the complete combustion of wood gases, means that combustion takes place at a temperature where atmospheric oxygen and nitrogen can chemically combine. The better the quality of the combustion control system on a biomass boiler, the lower the NOx emissions will be. In general, biomass boilers produce less NOx than oil boilers. Biomass boilers do not produce any oxides of sulphur (SOx).
After combustion, biomass-fired boiler fuel will generate energy and also produce some combustible matter in fly ash which will have bad influence on the surrounding environment. Therefore, in order to realize the goal of environmental protection, we should reduce the generation of combustible matter in fly ash in biomass-fired boiler fuel.
The pollution discharge of the biomass-fired boiler is less than the coal-fired boiler. It is also necessary to deal with the exhaust gas of the biomass-fired boiler to meet the national standards before boiler ignition and operation.
Discharging high-temperature flue gas generated by a biomass-fired boiler efficiently and safely is crucial for boiler operation, environmental compliance, and energy recovery. These gases, if not handled properly, can lead to energy inefficiency and increase the emission of pollutants. ZOZEN Boiler, as a professional industrial boiler manufacturer, incorporates advanced technologies and strategies to manage and utilize high-temperature flue gases from biomass-fired boilers. Here's an overview o...
Selecting a biomass-fired boiler for industrial applications involves careful consideration of various parameters to ensure efficiency, sustainability, and cost-effectiveness. Biomass boilers offer an eco-friendly alternative to fossil fuel-based boilers by utilizing renewable resources like wood chips, pellets, and agricultural waste. When choosing a biomass-fired boiler, pay attention to the following parameters:
1. Fuel Type and Availability:
Type of Biomass: The type of biomass fuel availa...
Biomass boilers do produce emissions when they burn organic materials such as wood chips, pellets, or agricultural waste. The exact type and amount of emissions depend on various factors such as the type of fuel used, combustion efficiency, and air pollution control technologies in place. However, with proper design and operation, biomass boilers can emit significantly less pollutants than traditional fossil fuel boilers, making them a more environmentally friendly option for heat and power...
High exhaust temperature in a biomass-fired boiler can be caused by several factors, including:
1. Insufficient air supply: If there is not enough air supplied to the combustion chamber, the fuel may not burn completely, resulting in high exhaust temperatures.
2. Excessive fuel supply: Excessive fuel supply can overload the boiler, causing incomplete combustion and high exhaust temperatures.
3. Improper combustion: Improper combustion can lead to incomplete fuel burning and high exhaust tempe...
A biomass-fired boiler furnace that has multiple issues such as wall cracks, deformation, coking, and tilt, loose bricks, tube wall blockage, burned-out rock wool sealing, and combustion chamber wall damage requires immediate attention to prevent further damage and potential safety hazards.
Firstly, it is recommended to shut down the boiler immediately to prevent any further damage and ensure the safety of the surrounding area. The boiler should not be restarted until all necessary repa...
