There are two types of burners for industrial steam boilers, depending on how they control the mixture of air and fuel at the key point in the boiler's operation, which is the generation of combustion.
The pharmaceutical sector is an area that requires the highest quality steam for its processes, known as clean steam, instead of other industrial steams. Some processes in this sector even need the highest level of quality - pure steam, which involves even stricter steam purity requirements for use in the sterilization of raw materials and pharmaceutical products at high temperatures.
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).
Combustion Efficiency
Combustion efficiency is the effectiveness of the burner only and relates to its ability to completely burn the fuel. The boiler has little bearing on combustion efficiency. A well-designed burner will operate with as little as 15% to 20% excess air, while converting all combustibles in the fuel to thermal energy.
Thermal Efficiency
Thermal efficiency is the effectiveness of the heat transfer in a boiler. It does not take into account boiler radiation and convection losses - for example, from the boiler shell, water column piping, etc.
Fuel-to-Steam Efficiency
The air oxygen content's effect on the boiler is mainly reflected by the effect on the blowing rate. Boiler will have typical phenomena if the blowing rate is high or low.
Carrying out the exhaust work of a thermal oil heater smoothly is essential for maintaining the efficiency, safety, and longevity of the system. Proper exhaust management ensures that combustion gases are safely discharged, prevents back pressure, and maintains optimal combustion conditions. ZOZEN Boiler, with its extensive experience in designing and manufacturing industrial boilers and thermal oil heaters, employs a comprehensive approach to ensure efficient and safe exhaust systems. Here's ho...
In thermal fluid systems, the choice of materials for valves, piping, gaskets, and other components is critical to ensure the system's integrity, efficiency, and safety. These materials must be compatible with the thermal fluid used, capable of withstanding the operating temperatures and pressures, and resistant to corrosion. As a leader in industrial boiler manufacturing, ZOZEN Boiler emphasizes the importance of selecting the right materials for each component of a thermal fluid system. Below ...
Testing a boiler's energy efficiency is essential for identifying how well it converts fuel into heat and for determining potential areas for improvement. As a professional industrial boiler manufacturer, ZOZEN Boiler emphasizes the importance of regular efficiency assessments to optimize performance, reduce fuel consumption, and minimize environmental impact. Here's a comprehensive approach to testing your boiler's energy efficiency:
