The slag produced by a biomass-fired boiler can be reused to avoid energy waste and environmental pollution. There are many ways to reuse the slag. For example, the slag can be used to improve soil and improve soil performance. If it contains potassium carbonate and organic matter, it can also be used to produce compound fertilizers. In addition, the slag is a kind of plant ash, it is also a good thermal insulation material for steelmaking.
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 load control is quite significant in boiler’s operation. Both overloaded and ultra-low loaded operations have negative effects on boiler. Different types of boiler have different rated load ranges, but ultra-low loaded operation’s harm to different types of boiler is similar.
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...
Radiation and convection losses will vary with boiler type, size, and operating pressure. The losses are typically considered constant in BTU/hr, but become a larger percentage loss as the firing rate decreases. Boiler design factors that also impact efficiencies of the boiler are heating surface, flue gas passes, and design of the boiler and burner package.
If the pumps of a coal-fired boiler are not absorbing water, it could be due to several reasons. It's essential to diagnose the issue accurately for an effective solution. Here are some common causes:
Air Locks in the Pump or Suction Line: If there is trapped air within the pump or the suction line, it can prevent the pump from creating the necessary vacuum to draw water.
Low Water Level in the Feed Tank: If the water level in the feed tank is too low, the pump may not have enough water to dra...
Identify the Cause: Before attempting to fix the issue, it's important to understand why the grates are stuck. Common reasons include excessive ash accumulation, warped grates due to overheating, mechanical failures, or obstructions caused by foreign objects.
Shut Down the Heater: For safety, turn off the heater before inspecting or repairing the grates. Ensure that all safety protocols are followed to prevent accidents.
Inspect for Ash and Debris: Check the grates for any ash buildup or forei...
Drying the moisture in the fuel of a biomass-fired boiler is important to ensure efficient combustion and prevent issues such as fuel bridging, clumping, and poor boiler performance. Here are some methods that can be used to dry the moisture in biomass fuel:
1. Sun drying: This method involves spreading the biomass fuel, such as wood chips or sawdust, in a thin layer in a sunny, well-ventilated area. The sun's heat and wind will help to evaporate the moisture in the fuel.
2. Fo...
