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...
Regular maintenance is essential to ensure safe and efficient operation of industrial thermal oil heaters. Here are some of the key maintenance tasks that should be performed:
1. Daily checks: The operator should perform daily checks of the heater, including checking the fuel level, the temperature of the thermal oil, and the pressure of the system.
2. Cleaning: The heater should be cleaned regularly to remove any buildup of soot, ash, or other debris that can reduce efficiency or cause damage...
Boiler economizers are devices that help to improve the efficiency of industrial boilers by recovering heat from the flue gas and transferring it to the boiler feedwater. In this article, we will explore how boiler economizers work and the benefits they offer. We will also introduce ZOZEN's boiler and economizer solutions that can help improve the energy efficiency of your industrial operations.
How Do Boiler Economizers Work?
A boiler economizer is essentially a heat exchanger that recovers w...
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 ...
The boiler manhole-lids are mounted from the inside of the boiler so that the boiler pressure will help to keep them tight. Hence the manholes have to be elliptical in shape to make it possible to take the lid out from the boiler.
1) The insufficient heating surface. In the process of retrofit design or improvement, increase the heating surface.
2) The particle size of the fuel is large, the screening characteristics do not meet the requirements, the material concentration in the suspension section is low, and the heat transfer coefficient is small, which makes the output unable to go up, or shows that the bed temperature is high and coal cannot be added. The solution is to improve the fuel preparation system and control...
As a kind of special equipment, industrial boiler is special and complex. Complete inspection can ensure the safety operation of the boiler.
The external inspection of the boiler is generally conducted once a year, the internal inspection is generally conducted once every two years, and the hydrostatic test is generally conducted once every six years.
For boilers that cannot be inspected internally, a water pressure test should be conducted every three years. The internal ...
