Block 1 - Installation of ICI Burners Flashcards
What is essential to follow when performing a burner installation?
Manufacturer’s instructions and specifications
This ensures the installation is done correctly.
What is commonly used to ensure a good seal between the burner and the combustion chamber?
A gasket
This is placed between the burner and combustion chamber flanges.
What type of gasket should be used for burner installation?
OEM type gasket
These gaskets are intended for the specific application.
What should be applied to hold the rope seal in place during installation?
High temperature silicon
Some manufacturers recommend this for securing the rope seal.
What is the first step to prevent air leakage when mounting a burner?
Hand tighten the bolts
Then check that the burner is seated evenly around the flange.
What should be done after the first firing of the burner?
Retighten all bolts
This should also be done regularly after commissioning.
What may be required in addition to the burner flange mounting system for support?
Burner and pipe manifold support
This is necessary for the weight of the burner and connected pipe train components.
What is frequently the cause of burner block and casing failure?
External stresses and strains transmitted through the piping
Flexible connections are recommended to reduce these stresses.
What is a specialized component that some burners come with?
Refractory block
These can be replaced, requiring burner removal for access.
What should be used around the block and frame sub-assembly for the Maxon RAMFIRE installation?
Fiber blanket
This helps to tightly seal around the block.
What is the first step in preparing the burner mounting in a refractory wall?
Use casable refractory rammed into the space around the burner
Supported with angle iron and retained by masonry-coated anchors.
What should be packed in the remaining gap around the burner block in a refractory wall?
Ceramic fiber insulation
This ensures good thermal protection.
What must be protected from hot gas flows for maximum burner life?
Burner frame and furnace shell
High temperature gasketing should be used between the burner mounting flange and furnace shell.
What is required for most installations according to Level 1?
Design registration process
This is a regulatory requirement for safety.
What types of gas systems require design registration?
Natural gas, propane, digester gas, manufactured gas, liquefied petroleum gas, landfill gas, hydrogen
This is in accordance with the Safety Standard Act and Gas Safety Regulation.
What process applies only to Non-Certified Gas Appliances?
Product approval process
This ensures compliance with gas appliance approval directives.
What must a gas appliance have before it can be placed into operation?
A label or mark
This is detailed in section 31 of the Gas Safety Regulations.
What must be compatible with the burner nameplate ratings?
Electrical service voltage, phase, and cycle
This is critical for safe operation.
According to the Canadian Electrical Code, how should wiring be installed?
According to use and environment
This ensures compliance and safety.
What types of conditions must be considered for burner wiring?
Vibration or heat, sensors or motors, wet or dry
These factors influence installation practices.
What is the first step when installing an ICI burner?
Follow the manufacturer’s instructions and specifications
What must be obtained for a non-certified gas appliance before it can be operated?
A gas appliance approval label or mark
What is recommended to reduce stresses and strains on the burner due to piping?
Use flexible connections in all piping
In what type of wall installation is a burner block sleeve typically required?
Soft wall
What is required for industrial and commercial gas systems to comply with regulations?
The design registration process
When installing wiring for the burner, what must it be compatible with?
Burner nameplate ratings and the Canadian Electrical Code
What is the primary purpose of using a gasket between the burner and the combustion chamber?
To ensure a proper seal and prevent air leakage
What material should be used to pack the remaining space around a refractory block in a soft wall installation?
Ceramic fiber insulation
Which material is recommended for making a gasket if an OEM gasket is unavailable?
Rope or fiber gasket material
What should be done after tightening the burner bolts for the first time?
Retighten all bolts after the first firing and regularly during commissioning
