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.
Because coal fuel is expensive and coal combustion can cause serious environmental pollution, it is necessary to transform the coal-fired boiler into gas-fired boiler. However, the reconstruction of coal-fired boiler is not a small project. Only pay close attention to every phase of the reconstruction process can avoid failure.
(1)Ensure normal and stable steam pressure, steam temperature and evaporation.
(2)Avoid coking and burner damage; Ensure the safety of the operation of the superheater; Reduce pollution of combustion.
(3)Make the operation achieve the highest economy.
The heating load of an industrial boiler refers to the amount of energy required to generate a certain amount of heat in a specific period, usually measured in British Thermal Units (BTUs) per hour, kilowatts (kW), or megawatts (MW). Essentially, it's the amount of energy needed to heat the water or generate steam in the boiler for industrial processes or heating purposes.
Understanding the heating load is crucial for several reasons:
Boiler Sizing: Accurately determining the heating load is e...
Serious coal leakages in the fire grate of coal-fired boilers can be caused by several factors, each impacting the efficiency and safety of the boiler operation. Understanding and addressing these issues is crucial for maintaining optimal performance. Here are some common causes:
Wear and Tear: Over time, the fire grate components can wear down due to the constant exposure to high temperatures and the abrasive nature of coal. This wear can create gaps through which coal can fall.
Improper Grat...
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...
Increased Efficiency: Economizers and condensers are designed to capture and utilize the waste heat from boiler flue gases. This process significantly improves the overall efficiency of the heating system.
Reduced Fuel Consumption: By maximizing heat recovery, these devices lower the amount of fuel needed to reach the desired temperature, leading to substantial fuel savings and reduced operating costs.
Lower Emissions: Improved efficiency translates to less fuel burned, which directly reduces ...
