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).
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...
According to the characteristics of biomass fuel, the biomass boiler produced by ZOZEN Boiler has been specially designed in structure, which has taken the lead in solving the problems such as furnace arch collapse, furnace door burn-out, hopper fire and stopper coking.
Hot-water boiler is a kind of thermal equipment that uses the heat energy released by fuel combustion or other heat energy (such as electric energy, solar energy, etc.) to heat water to the rated temperature. According to different fuels, hot water boilers can be divided into gas-fired hot water boilers, oil-fired hot water boilers, biomass-fired hot water boilers, and coal-fired hot water boilers. How to choose hot water boiler? We will focus on the heating, pressure and thermal efficiency of hot water boiler.
Agglomeration problem mainly occurs on the fireside in the fluidized bed boilers. Agglomeration is basically the ash-related problem of biomass-fired boilers. Ashes which are formed from high-sulfur and low-ash fuel agglomerate if they are prone to sulfating condition for long time.
The answer is yes. The bagasse boiler is a distinctive biomass boiler. According to its specific application, it can also be said to be a bagasse biomass power generation boiler. The bagasse boiler is mainly used for power generation, especially large-scale bagasse biomass boiler equipment, such as 75 tons/hour bagasse power generation boiler, 150 tons bagasse boiler, and 180 tons power generation boiler.
Biomass fuel can be applied to a biomass-fired boiler by treatment and compression molding. Commonly used are straw particles, rice husk particles, wood particles, sawdust particles, peanut rod particles, sugar aldehyde residue particles, palm shell particles and so on.
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.
