The pollution discharge of the biomass-fired boiler is less than the coal-fired boiler. It is also necessary to deal with the exhaust gas of the biomass-fired boiler to meet the national standards before boiler ignition and operation.
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.
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.
Biomass-fired boilers are increasingly popular due to their renewable and sustainable fuel source. However, like any combustion process, biomass boilers do produce emissions, including smoke and other gases, which can have environmental and health impacts if not properly managed.
What Are Biomass-Fired Boilers?Biomass boilers use organic materials, such as wood chips, pellets, or agricultural waste, as fuel to generate heat or electricity. They are considered more eco-friendly compared to fossi...
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 ...
There are several ways to estimate the thermal efficiency of gas-fired boilers:
1. Direct method: This method involves measuring the amount of fuel consumed and the amount of heat produced by the boiler. By comparing these two values, it is possible to calculate the thermal efficiency of the boiler.
2. Indirect method: The indirect method involves measuring various parameters such as flue gas temperature, ambient air temperature, and fuel consumption, and then calculating the t...
High exhaust temperature in a biomass-fired boiler can be caused by several factors, including:
1. Insufficient air supply: If there is not enough air supplied to the combustion chamber, the fuel may not burn completely, resulting in high exhaust temperatures.
2. Excessive fuel supply: Excessive fuel supply can overload the boiler, causing incomplete combustion and high exhaust temperatures.
3. Improper combustion: Improper combustion can lead to incomplete fuel burning and high exhaust tempe...
A biomass-fired boiler furnace that has multiple issues such as wall cracks, deformation, coking, and tilt, loose bricks, tube wall blockage, burned-out rock wool sealing, and combustion chamber wall damage requires immediate attention to prevent further damage and potential safety hazards.
Firstly, it is recommended to shut down the boiler immediately to prevent any further damage and ensure the safety of the surrounding area. The boiler should not be restarted until all necessary repa...
