Industrial Burner
One of the crucial components in heating systems and energy production that converts various fuels into heat is the industrial burner. These burners are widely used in industries like refineries, chemical plants, power plants, and central heating systems. Ensuring the efficient operation of industrial burners is not only crucial for maximizing energy output but also for significantly reducing operational costs.
Types of Industrial Burners
These burners are categorized into several types based on the fuel type and applications. Below is an overview of the different types of industrial burners:
Gas-fired Burner
In this type of burner, natural gas is used as primary fuel. Natural gas is one of the most popular fuels for industrial burners due to its affordability, cleanliness, and availability. These burners are highly efficient because of their complete combustion and precise control. Additionally, gas-fired burners offer lower emission levels compared to other types of burners, making them an ideal choice for industries that prioritize environmental protection. These burners are commonly used in industries such as food processing, petrochemicals, power plants, and other sectors that demand high heat output.
Oil-fired Burner
These burners use liquid fuel (oil), making them a popular choice in regions with limited access to natural gas or where oil offers a more cost-effective solution. Oil-fired burners are commonly used to generate heat in boilers, furnaces, and other industrial heating equipment. Given the characteristics of the oil fuel, these burners require advanced equipment to optimize combustion and reduce emissions. Although oil-fired burners typically produce more pollutants than their gas-fired counterparts, proper adjustments can significantly lower pollution levels.
Heavy Oil Burner
Heavy oil burners use mazut that is recognized for high calorific value. Due to the lower cost and high energy content of mazut, these burners are commonly used in refineries, cement plants, and power generation facilities. Heavy fuel oil burners necessitate pre-heating equipment due to the high viscosity of mazut. This fuel has high viscosity and must be warmed before combustion to ensure smooth flow through the fuel pipes and nozzles. As a result of using this type of fuel, these burners create significantly higher pollution levels compared to gas-fired burners.
Multi-fuel Burner
These burners are designed to use various types of fuels, either simultaneously or independently. This feature makes them highly adaptable for industries that require flexibility in fuel types, especially when the price or availability of a specific fuel fluctuates. The multi-fuel burners are equipped with advanced control systems that efficiently manage the consumption and combustion of multiple fuels at once. These burners are widely used in industries with complex processes that prioritize energy optimization, such as refineries and power plants.
Dual-fuel burners are the most common types of multi-fuel burners. Dual-fuel burners can use two types of fuel, typically natural gas and oil. In situations where natural gas is unavailable, the dual-fuel (gas-oil) burner automatically shifts to the oil fuel. This capability not only improves energy efficiency but also minimizes interruptions in production processes.
Components of Industrial Burner
Industrial burners consist of several important components, each playing a significant role in the efficient operation of the burner. The main components of industrial burners are described in detail in the following section:
Fuel Train
The fuel line is responsible for supplying fuel and creating the appropriate pressure and flow rate before it reaches the burner. The gas fuel train includes equipment such as filters, regulators, safety valves, main valves, pressure switches, butterfly valves, gas pressure sensors, and more. The liquid fuel train includes pump, solenoid valve, fuel regulator, and more.
Combustion Head
The combustion system is responsible for delivering fuel to the combustion chamber and mixing it with air. Depending on the type of fuel (gas, liquid, or solid), this system includes various components:
Gas Nozzles: In gas-fired burners, the nozzles and gas pipes inject the fuel in the appropriate direction and position.
Liquid Fuel Nozzles: In liquid fuel burners, such as those using oil or mazut, the nozzles are used to spray the fuel in fine droplets. This spraying ensures that the fuel mixes well with the air, leading to more complete combustion.
Air Supply System
The air supply system is a critical component of industrial burners, responsible for delivering the required air or oxygen for efficient combustion. Below are the key components of the air supply system:
Fans: Powerful fans are essential for blowing air into the burner, ensuring proper mixing with fuel to facilitate the combustion process. These fans are in various sizes and capacities, tailored to the specific type of burner and the required airflow for optimized operation.
Dampers: Regulating airflow is done by dampers. They can be controlled either manually or automatically, allowing for precise adjustments. By adjusting the dampers, the air/fuel ratio can be controlled which leads to maximizing efficiency and reducing emissions.
Air Duct: Industrial burners are classified into two types based on their configurations: monoblock and dual block. In monoblock burners, the fan is directly connected to the burner, providing a compact design. In contrast, dual block burners feature a separate fan that connects to the burner via an air duct. In this design, the outlet air is directed to the burner through the duct.
Ignition System
This system is responsible for starting the combustion process. The components of ignition system are as follows:
Pilot: To initiate the combustion process in large burners, small burners known as pilot burners are used. The pilot burner is activated first for running the burner, generating a small flame. After the pilot is established, the main fuel is injected, leading to the creation of the main flame. The pilot flame is crucial to have a safe combustion start. Once the main flame stabilizes, the pilot burner is turned off.
Ignition Electrodes: These electrodes create an ignition that leads to combustion of the air and fuel mixture in the pilot. The pilot is not used in small burners instead the ignition electrodes directly generate the main flame.
Burner Electrical Panel
It includes the power circuit and control system. The other parts in this panel are as follows: motor starters, contactors, terminals, wiring and protective components of the electronic system of the burner such as fuses.
Burner Control System
This system acts as the brain of the burner, monitoring and regulating all processes. This system includes the following components:
Controllers: The analog or digital controllers are responsible for monitoring temperature, pressure, air/fuel ratio, and other operational parameters. Based on the conditions, they send necessary commands to different parts of the burner and actuators.
Sensors: Sensors of temperature, pressure, and exhaust gas analyzers that send precise data about the burner’s conditions to the controllers.
Actuators and Automatic Valves: Linear actuators, servomotors, and solenoid valves that control the flow of fuel and air based on commands received from the controller.
Safety System
Safety systems in industrial burners play an important role in preventing accidents. These systems include the following:
Safety Valves: Valves that shut off the fuel flow in case of excessive increase or decrease in pressure.
Flame Detection System: This system continuously monitors the flame, and if the flame goes out due to technical failure or disruption in fuel flow, it cuts off the fuel supply to prevent potential hazards.
Pressure Switches: These switches are responsible for monitoring the air and fuel pressure in the burner. If the pressure decreases or increases excessively, they will cause the burner to stop functioning.
Emergency Shutdown Systems: These systems automatically turn off the burner in hazardous situations and prevent its operation.
Alarms and Warnings: Systems that notify the operator in case of any malfunction or abnormal change in the burner’s operation.
Operation of Industrial Burners
Industrial burners, used in heating systems and energy production, are responsible for converting the chemical energy of fuel into heat. The operation of these burners involves several important steps, explained as follows:
Air Supply
The first step in the operation of a burner is creating sufficient airflow. For a complete combustion of the fuel, oxygen is needed, which is supplied to the burner through an air supply system. In industrial burners, the air supply system includes fans and electromotor that blow combustion air into the burner. The correct air/fuel ratio is crucial for optimal combustion. Therefore, precise control systems are used in burners to adjust this ratio.
Fuel Injection
After establishing the necessary airflow, fuel is injected into the combustion chamber. The fuel, can be natural gas, oil, heavy oil, or a combination of various fuels, is transferred into the burner through an injection system. In gas burners, fuel enters the combustion chamber as gaseous form, while in liquid burners like oil or heavy oil, it is sprayed in as liquid through pumps and nozzles.
Fuel and Air Mixing
In the combustion chamber, fuel and air are completely mixed. This process is precisely done to ensure optimal combustion. In gas burners, the gas is combined with the air. In liquid burners, the fuel is atomized (sprayed) through nozzles and mixed with the inlet air.
Combustion
After mixing the fuel and air, the mixture is ready for combustion. During this step, the ignition system (pilot or ignition electrodes) is activated to create a flame and initiate the combustion process. The flame is formed in the combustion chamber which leads to producing thermal energy.
Control and Regulation
To ensure optimal and safe operation, industrial burners are equipped with advanced control systems. These systems continuously monitor temperature, pressure, air/fuel ratio, and other important parameters. They can be adapted to changes in operational conditions to ensure that the system operates with minimal emissions and maximum efficiency, preventing incomplete combustion or excessive pollutant emissions.
Flue Gas Removal
After combustion, the flue gases (such as carbon dioxide and water vapor) get outside the system through chimneys and exhaust systems.
Smart Industrial Burners
Smart industrial burners, using modern technologies, provide an advanced solution for managing and controlling the combustion process. These burners precisely regulate the air/fuel ratio and continuously monitor temperature and pressure.
