During the ignition and operation of the chamber combustion boiler fueled by pulverized coal, oil or combustible gas, improper operation can cause the deflagration or secondary combustion in the furnace or flue gas duct, which can further cause the increased pressure in the furnace. When the pressure reaches a certain value, the explosion-proof door is necessary to open automatically to protect the furnace wall of the boiler.
Combustion Efficiency
Combustion efficiency is the effectiveness of the burner only and relates to its ability to completely burn the fuel. The boiler has little bearing on combustion efficiency. A well-designed burner will operate with as little as 15% to 20% excess air, while converting all combustibles in the fuel to thermal energy.
Thermal Efficiency
Thermal efficiency is the effectiveness of the heat transfer in a boiler. It does not take into account boiler radiation and convection losses - for example, from the boiler shell, water column piping, etc.
Fuel-to-Steam Efficiency
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.
The thermal efficiency of an industrial boiler is a measure of how effectively the boiler converts the energy contained in the fuel into usable heat. It is typically expressed as a percentage, indicating the ratio of heat output for heating or producing steam to the energy input from the fuel consumed. This efficiency is crucial for understanding the performance of a boiler, as it directly impacts fuel consumption, operational costs, and environmental emissions.
Factors Influencing Thermal Effi...
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.
Heating surface is one criterion used when comparing boilers. Boilers with higher heating surface per boiler horsepower tend to be more efficient. Traditional packaged boilers are offered with 5 square feet of heating surface per boiler horsepower as an optimum design for peak efficiency, but new design breakthroughs allow ZOZEN boilers to have increased efficiency using more effective heating surface and reducing the size of the footprint.
An oil boiler's burner lockout is a common issue that can disrupt heating processes in various industrial and residential settings. This problem occurs when the boiler's control system detects a fault and, as a safety measure, shuts down the burner to prevent further damage or hazards. As a professional industrial boiler manufacturer, ZOZEN Boiler emphasizes the importance of understanding the underlying causes of burner lockouts to ensure timely and effective solutions. Here, we explore the pri...
The impact of fuel on boiler performance is significant and multifaceted, affecting everything from efficiency and operating costs to maintenance requirements and environmental emissions. As a professional industrial boiler manufacturer, ZOZEN Boiler emphasizes the critical role that fuel quality and type play in the operational efficacy, longevity, and sustainability of boiler systems. Here's an overview of how fuel impacts boiler performance:
1. Efficiency and Heat ValueThe type and quality o...
