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...
When it comes to coal fired boilers, the rear arch plays a critical role in the combustion process. The main function of the rear arch is to keep the fuel particles in suspension and prevent them from falling into the ash hopper, which can lead to incomplete combustion and decreased efficiency.
At ZOZEN, we understand the importance of a well-designed rear arch for coal fired boilers. That's why our coal fired boilers are equipped with advanced rear arch designs that enhance the combust...
The coal-fired boiler uses coal as fuel. The consumption of coal is a key factor to measure the efficiency of boilers. Under the same condition, the coal-fired boiler with less coal consumption can save more costs for enterprises. However, the coal consumption of coal-fired boilers is related to many factors, such as the efficiency of the boiler, the calorific value of fuel coal and the degree of coal combustion.
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 ...
An Interlock in the boiler’s control system is a programmed or hardwired condition that forces a device to be in a pre-determined or permissive state before the process can continue.
Depending on design pressure, fuel type, either liquid, gas or solid, all steam boiler require interlocks to sequence the operation and to prevent damage to the boiler. Examples of such devices are High or Low Boiler Drum Water Level, Low Boiler Feed Pump Pressure, High or Low Fuel pressure, High or Low Atomization pressure (oil fired), Proof of Ignition, Proof of Flame, FD and/or ID (solid fuel) Fan Motor Operation or combustion air pressure, Damper or Valve position and High Boiler Steam Pressure as well as O2 and furnace temperature.
First of all, the boiler water and steam are two concepts. It is the unit of measurement for boiling water boiler. What is a boiled water boiler? It belongs to the category of normal pressure hot water boiler, which heats the water temperature to boiling state. To ensure safety in use, the top of the boiler is provided with a nozzle communicated with the atmosphere. If steam is discharged automatically, the boiler will always work under normal pressure, so its attribute is normal pressure hot water boiler.
First, let's explain what an industrial oil-fired boiler is. The industrial oil-fired boilers refer to boilers that use oil as the fuel. Generally, they burn diesel oil, special fuel oil for boilers, heavy oil and waste oil, etc. However, due to the rising price of diesel oil and the problem of supply, they are now turning to fuel oil.
The gas-fired boiler is operated by an advanced combustion machine, equipped with automatic gas supply and ignition combustion system, and the gaseous fuel is easy to burn. Therefore, the gas-fired boilers need not be equipped with blower and induced draft fan components.
