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).
Heating surface is one criterion used when comparing boilers. Boilers with higher heating surface per boiler horsepower tend to be more efficient. Traditional packaged boilers are offered with 5 square feet of heating surface per boiler horsepower as an optimum design for peak efficiency, but new design breakthroughs allow ZOZEN boilers to have increased efficiency using more effective heating surface and reducing the size of the footprint.
The impact of fuel on boiler performance is significant and multifaceted, affecting everything from efficiency and operating costs to maintenance requirements and environmental emissions. As a professional industrial boiler manufacturer, ZOZEN Boiler emphasizes the critical role that fuel quality and type play in the operational efficacy, longevity, and sustainability of boiler systems. Here's an overview of how fuel impacts boiler performance:
1. Efficiency and Heat ValueThe type and quality o...
Typically, a steam boiler should receive servicing at least once per year. Any kind of safety failure with a boiler can have serious consequences, and so a yearly inspection will help to spot any safety issues that need to be addressed. Servicing your boiler on a regular basis can also help you to save money on repairs. If you spot a problem during routine maintenance, there's a good chance you'll be able to fix it at a much cheaper cost than if the problem goes unnoticed and becomes a larger and more serious issue.
Soot on the heating surfaces. Even a thin layer of soot will reduce the boiler efficiency. Not the right fuel for the burner. For instance, diesel oil to a rotary cup burner wouldn't do. Too low feed water temperature.
1.Flamelifting caused by a sudden increase of gas pressure;
2.Gas supply disruptions caused by malfunction of solenoid valve;
3.Great gas constituent change and excessive moisture content.
1. The fuel volume is 1 / 30 ~ 40 of the raw material volume after molding;
2. The specific gravity is 10-15 times of the raw material, and the moisture content is between 12% and 18% (the moisture content of coal is below 10-15);
3. The net calorific value can reach 3500-4500 kcal (the net calorific value of class II bituminous coal is 3700-4700 kcal / kg);
4. The ash content is less than 10% (the ash content of coal is more than 20%);
5. Volatile matter ≥ 65.62% (volatile matter of class II bituminous coal≥20%).
6. Biomass fuel belongs to renewable clean energy, which is the same as wind energy and solar energy. The biomass fuel is rich in resources, it can ensure the sustainable use of energy.
7. The sulfur content and nitrogen content of biomass fuel are low, the amount of SOx and NOx generated in the combustion process is low.
Boiler controls provide an extra level of safety and reassurance: they allow you to understand your boiler's daily operations better, as well as perform the crucial duty of ensuring that your boiler is operating safely and efficiently. Regardless of what kind of industrial or commercial operation you run, here are some must-have boiler controls to get the most out of your equipment.
