Differences Between Integrated and Split Burners


Integrated and split burners differ in several ways, as follows:


Structural Design


Integrated burners combine the burner body, burner blower, and combustion system (including pumps, solenoid valves, servo motors, etc.) into a compact structure.


Split burners combine the burner body (including the burner head, fuel or gas system), burner blower, and burner control system (including the control box, blower thermal relay, AC contactor, etc.) into independent systems, which are installed separately.


Installation


Integrated burners have a compact structure and are relatively small in size. Installation requires only securing the burner to the equipment and connecting the fuel lines and power supply. Installation is quick and easy, requiring relatively little space, making them suitable for small equipment or locations with limited space.


Because split-unit burners have independent components, installation requires the burner body, blower, and control system to be installed separately. This requires careful consideration of the connections and layout between these components, making the installation process relatively complex and requiring specialized installation personnel and a larger installation space. However, flexible layouts can be tailored to specific site conditions and requirements, making them suitable for large-scale equipment or complex industrial production environments.


Performance and Features


The combustion system, blower, and control system of a split-unit burner are integrated, ensuring seamless coordination and stable combustion. However, the blower in a split-unit burner is typically an axial flow blower, resulting in relatively low air pressure, which may not meet the requirements in applications requiring high air volume and pressure.


Split-unit burners have an independent air supply system, allowing for the selection of appropriate blowers, such as centrifugal blowers, to meet specific operating conditions. These blowers provide high air pressure and volume, meeting the requirements of large-scale equipment or applications requiring high combustion intensity. Furthermore, split-unit burners offer greater flexibility in fuel distribution and regulation, allowing for precise adjustment of the fuel-air ratio through an independent control system, contributing to environmentally friendly combustion, such as achieving low-NOx combustion.


Maintenance


Because all components of a monoblock burner are integrated, maintenance may require disassembly of the entire burner from the equipment. This, combined with the complex internal structure and limited access, increases maintenance difficulty and cost. If a component fails, the entire burner may need to be replaced, resulting in high repair costs.


A split-unit burner, with its independent components and relatively simple structure, is easy to disassemble and clean. If a component fails, it can be repaired or replaced individually without disassembling the entire burner, reducing downtime and repair costs and making maintenance more convenient and quicker.


Applicable Applications


Monoblock burners are suitable for applications with relatively low combustion power, such as small and medium-sized fuel-fired boilers, fuel-fired hot air blowers, ovens, and small fuel-fired heating furnaces, where burner size and installation space are critical.


Split-unit burners are primarily used in large industrial boilers, kilns, and furnaces, as well as in applications with high combustion efficiency and environmental requirements or special operating environments (such as high temperatures and corrosive environments).


Cost and Price


Integrated burners are manufactured in high-volume batches, requiring less specialized supply chain expertise, resulting in a relatively low market price.


Split burners, due to their high specialized requirements, often require specialized installation teams. Furthermore, their complex structure and numerous components contribute to their relatively high market price.
