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
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...
Boiler grates are an essential component of industrial boilers as they provide a platform for fuel combustion. ZOZEN Boiler, as a leading manufacturer in the boiler industry, offers a variety of grate options to cater to different fuel types and combustion requirements. Here’s an overview of the common types of boiler grates and their characteristics:
1. Fixed Grate:Fixed grates are the simplest type of grate used in boiler systems. They are suitable for burning low-quality fuels with low...
Load tracking is an important feature of industrial boilers that helps to optimize their performance and efficiency. Load tracking refers to the ability of a boiler to adjust its output in response to changes in demand.
In an industrial setting, the demand for steam or hot water can vary significantly depending on factors such as production schedules, weather conditions, and other variables. Load tracking allows the boiler to adjust its output to match the changing demand, ensuring that...
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...
Question details (Performance) :
1. The vibrating coal grate stops running totally or intermittently.
2. The current of vibrating coal grate motor rises abnormally.
3. The safety clutch of transmission machine of grate or safety pin is broken.
Answer: cause of the problem:
Boiler’s vibrating coal grate is a rotating combustion equipment, due to the bad working conditions, stuck stalling is easily happened and grate failure happens in daily application and ...
1. If there is air in the pump or suction pipe, the air should be discharged.
2. If the depth of the bottom valve immersed in the water is not deep enough, the depth should be increased.
3. If the rotational speed is too slow or the conveyor belt is too loose, the rotational speed should be adjusted and the conveyor belt should be tightened.
4. If the impeller, suction pipe and bottom valve are blocked by dirt, you should check the pump body and clean the dirt.
5. If the height of water conveyance exceeds the regulations too much, the pump head should be adjusted to the specified range.
1. Sufficient furnace temperature: Sufficient fuel combustion of biomass-fired boilers firstly requires high furnace temperature. The temperature should meet the requirements of sufficient fuel combustion. Besides, the combustion speed is required to be proportional to the temperature. Moreover, the furnace temperature should be raised as much as possible on the premise that slag is not formed in the furnace.
