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.
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.
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.
When a Circulating Fluidized Bed (CFB) boiler encounters a cyclone separator breakdown, it's important to address the issue promptly and effectively to maintain the boiler's efficiency and safety. Here are steps that should be taken:
Immediate Shutdown: First and foremost, shut down the boiler following the standard shutdown procedures. This is crucial to prevent any further damage to the boiler and to ensure safety.
Inspection and Diagnosis: Once the boiler is safely shut down, conduct a thor...
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...
If the burner motor of a gas-fired boiler is running and voltage is present at the controller terminal, but there is no ignition followed by a system failure and stop, this situation can be attributed to several potential issues. Here's a breakdown of what might be happening and what to check:
Ignition System Failure: The ignition system, which may include spark electrodes or an igniter, could be faulty. Check for any signs of damage, misalignment, or dirt on the igniter or electrodes.
Control...
Thermal fluid degradation or “burn-up” in a thermal fluid heater can be a significant issue that leads to the loss of fluid properties, system inefficiency, and potential equipment damage. Here are the common reasons why thermal heating fluid may degrade or burn up in your thermal fluid heater:
1. Overheating:
Exceeding the thermal fluid’s maximum recommended operating temperature can lead to ‘cracking’ or breaking down of the fluid. This may produce low molecular...
Using artificially softened water in the heating circuit with your boiler can potentially cause issues and is not recommended.
Artificially softened water contains high levels of sodium ions, which can cause corrosion of the boiler and other components in the heating system. This corrosion can damage the boiler and other components, leading to leaks and reduced efficiency.
In addition, artificially softened water can cause problems with water pressure and flow rate, which can i...
